Hey all, new to the site. Have a rifle on the way, an old German Weatherby Mark V in 270 Weatherby Mag. Less than 80 rounds through it. I am hoping the 150 Accubonds shoot good. 2nd choice would be 150/140 Grain Ballistic Tip. Any other loads I should try? Not looking to reload at this point though we do have the equipment (hasnt been used in 10 years +) My Dads 300 Weatherby only shoots 1.5" groups at best so I am not expecting too much for accuracy.
Thanks!
 
Most Weatherby's Shoot better than 1.5!









I know so many people in so many places
They make allot of money but they got sad faces

I owned a 270 Wby for a while but it went down the road to help pay for another sheep hunt.
It was a great shooting rifle so don't short-change it.
You'll find something in factory loads to work at MOA or less but proper reloading and experimenting is the better way to go when you get around to it.

I think you'll like the rifle just fine. I was shooting the Barnes Triple Shock, but switched to the Accubond because I wasn't satisfied with grouping.
The Accubond is exceptional! The Barnes were shooting better than 1.5", I just wanted something tighter for longer range shooting.

My father in law had both 300 and 7mm Weatherby mags made in Germany with custom stocks. He worked up handloads that would group 3/4 to 1/2 inch at 100 yards for both rifles.
I suspect if you do more test shooting with different loads for that 300 mag you will get closer to 1 inch.
My father in law's go to powder for both mags was H-4831 powder that he bought from Hodgdon as surplus military powder.

Good to know. My dad's owned his 300 for over 20 years and even with reloads could he only flirt with 1" groups. His is a 80s-ish Japan model. The one on its way to me I'd a '59 German model. I'm a little worried about its age but I suppose if it has less than 80 rounds the rifling should still be good? Anyways, going to start with factory ammo first. I'll be tickled if I can get 1" groups with factory Nosler or Weatherby ammo.
 
If not neglected that bore should be in tip top shape after only 80 rounds. When you get it give the bore a good cleaning, use a good copper remover, before you test fire for groups. You may find that it has very little copper build up as the Saur company in Germany put high quality barrels on those Weatherby rifles.

LAST EDITED ON Dec-16-18 AT 06:35PM (MST)[p]Finally received the gun and got the scope mounted.....3-15 Zeiss Conquest HD5 x 50. I couldn't hit the broadside of a barn with it. I tried the 130 Grain Normas, 140 Grain Weatherby Ballistic Tip and 150 grain Nosler Accubond. I was hoping the Nosler Accubonds would be the ticket as thE BC is through the roof but it sprayed something terrible. 2 round's 2" apart followed by a flyer 8" high and right. Dad managed a few 1.5" groups with the Normas but I was beyond frustrated. I grabbed my old Husquavarna 7mm Mag (Timney trgger, 2.5 lbs) and shoot a 1" 3 shot group @ 100 yards. Come to find out, the trigger in the Weatherby was pulling anywhere from 5.5 to 6.5 lbs. We got it adjusted down to a hair over 3 lbs. I am anxious to try again with the trigger worked out, hoping for better results.
 
Is the stock tight? Double check the rings and bases to make sure they're tight and in good condition.

LAST EDITED ON Dec-16-18 AT 09:02PM (MST)[p]do what Justr_86 said. Make sure the action screws are tight then check the scope base and scope ring screws to make sure they are tight. Those weatherbys generate a lot of recoil and if the screws are not tight things can move around.

Make sure to clean the barrel very well of any possible copper fouling. If that does not take care of the problem, you may have a bedding problem that needs to be taken care of.
Most rifles shoot best if the barrel is free floated, but not everyone of them. I have found some that needed pressure at the fore end tip for accuracy.

If you have a wood stock on that gun, check the barrel to see if it is touching the wood channel on the side. If so that will throw shots off as the barrel heats up. Good wood stocks are great looking, but they can warp from humidity if not properly sealed.

If it appears to be a bedding problem, check to see if the action is glass bedded to the stock. If not you may need to have the action glass bedded to prevent it moving around due to recoil factors.

I glass bed all my bolt action rifles to improve accuracy. Some barrels are free floated, but I have one that I had to add 8 pounds of bedding pressure at the fore end tip to get accurate groups out of it.

I gave it a good cleaning afterwards. We shot probably 20 rounds and looked like it hadn't been cleaned prior to receiving the gun. The stock bolts weren't overly tight when I removed it so that may have been part of it. I also remember reading something about tightening the rear bolt to a specific amount using a torque wrench. I don't own but if it's that important maybe I need to try it? It's the original wood stock and is not glass bedded. Scope and rings are on there good and tight.

As far as glass bedding goes, how do you even start to know where the stock needs bedding at? I've heard of just bedding in the lugs by the receiver, the rear end by the bolt an even hanging weights off the barrel and bedding the whole stock.

I'm thinking the trigger was the biggest culprit but we will find out hopefully this weekend.
 
Thanks, I agree. I am hoping the trigger adjustment will correct the issue. What are yalls favorite hunting rounds for this caliber?

I was hoping the 150 grain Accubond would pattern well enough that I could use that to hunt inside of 300 yards. Second choice would be the 140/150 grain Ballistic tip and 3rd the 140/150 grain Partition. I know Barnes has some followers as do the Hornady SST, Berger bullets etc. My Dads always reloaded Nosler bullets so I am sort of biased to them for factory ammo.
 
Most 270 barrel twist is aimed at 130 grain bullets. Nosler bullets are great! The accubond is pretty much a partition with a higher bc. I shoot the accubond out of a few of my rifles and love them.

Good to know, I was just assuming 150 grain bullet would be a better hunting round because of the higher BC but I do want to find something that shoots accurate as well. The 130 grain Normas actually patterned the best thus far at appx. 1.5" groups however as bad as the trigger was, I am not counting that shooting session. Hopefully this weekend will yeild better results.I think for this gun in particular I would be willing to sacrifice accuracy for efficiency; ability to drop a deer at 300 yards with properly placed shot.
 
Lhedrick 1, stay with the 130 gr. Normas if they produced the best group in your previous testing. Accuracy with good shot placement is far more important then 20 gr. more bullet.
The standard 270 made it's reputation as a deer and elk killer with the 130 gr. bullet. You might consider trying other brands of 130 gr. bullets and get lucky and find the one particular load that gun will love and give you the accuracy you want.

None of the deer or elk I've shot with a 270 win and 130 grain bullets have had much of a chance to complain. My favorite bullet in that caliber is the 130 sierra game king. Cheap no frills bullets that are accurate and have never failed me.

Anything mag I try to go with a bonded bullet, usually the accubond.

Dear Mr. Lhedrick1

I would dearly like to say a few things....

#1) Your Post made me feel a desire to help but, I try to stop being helpful in Gun's

#2) Whilst I never jumped in on #1, many highly knowledgeable and experienced men did...and..Fast I might note.

#3) You seem to have a DESIRE and everyone here will give you their shirt to help, but..

#4) In #3 I spoke truth. However, in a Movie an Actor shouted aloud in Military Courtroom: "You Can't Handle The Truth".

#5) I need to suggest, with my most fond and kindness manner to ask that you Place the old Weatherby in a closet and leave it there. No more ammo needs to be fired through it and, Certainly, now, NOT BY YOU. No Offense intended.

#6) Find a manner to buy every issue of Precision Shooter Magazine and read every page. Then reread all of them.

#7) Locate a Shooting Range (any State) where there is a BENCH-REST Match. Go there with "NO RIFLE" and simply talk to the Shooters.

#8) If you can go to a Gun Shop or Gun Store or use the Internet, Seek, then Buy an Old Savage 110 Lever Action Rifle and use it for Deer shy of 500 Yards until you have done #6 & #7. I suggest the Chambering be 250-3000 (My Families Favorite) or heck, 300 Savage or whatever you desire. Hunt with this Lever Action until you are Old and Gray.

I could run list #'s far more but I must contain myself.

Insofar as Roy Weatherby's Rifle (I did know Roy then later, his Son..but that does not matter here)... Allow that Rifle to lean in the Closet until you have AT LEAST, 10 Years of Reloading Experience or, even if you never improve your Rifle IQ, don't touch it for 10 Years.

My Post here is meant to give YOU RESPECT and also, the Rifles New owner (YOU)... a chance to bond together in a Respectful Manner so later, you'll have your Dream Come true.

You will not achieve such now by buying factory ammo and Blasting away in a heated pursuit.

Hugs
Jagerdad :)
 
Oops'y ... I made an error. Its a Savage Model "99" Lever Action.... NOT a 110. My error was due to an outside influence... ie: Someone elses F.A.U.L.T. = as I typed, Elk phoned and asked me many, many life altering questions about being nice, jovial, a Lady'z man and gosh, endless more... So heck, I went on a Train ride, not a Trail ride with my Bump-Stock'ed Browning Semi Auto in 300 RUM. Schit'z happen'd far worse ?

Lhedrick1 Won mhore item; :) I have had the Honor of being the close friend of the Owner of; Precision Shooting Magazine ( Now gone ) and I have the Editors ( Dave Brennens ) Rifle that the HART Rifle Barrel Family built just for him. Just like Dave, I still have never fired it.

Lhedrick1, I will help you but you must deliver to me first: A Honda Trail 90 ( 110 ok ) and a WWII Jeep. Not exploded or burned up in a Fire as Eel offered.

Please Post a Picture of the Weatherby in the Closet...

Jagerdad :)
 
LAST EDITED ON Jan-04-19 AT 05:28PM (MST)[p]Update folks....RCBS dies just arrived today so haven't got the opportunity to reload this cartridge yet. Did get to shoot some 140 grain Nosler Ballistic tips. Grouping 1.5" - 2" with factory Weatherby ammo. Barrel has a slow 1:12" twist so excited to try reloading the 130 grain Accubond. This was AFTER adjusting the trigger from appx. 5.5 - 6 lbs down to 3 lbs. Still not a great trigger but much better than it was.
 
Hi I also own a Weatherby Mark V in 270 Weatherby Mag, 26 inch #2 barrel , as well as a Mark V in 300 Weatherby Mag 26 inch #2 and also a Mark V Ultralight in 270 Win. I load for all of them. Your German Weatherby most likely has a 12 twist. Please just check with Weatherby Customer service. You should get really excellent groups with the 130 Grn and 140 Grn Bullets, but the very long 150 grn may not group quite as well. They will still have accuracy suitable for hunting. The 170 Grn Berger's may produce disappointing groups in a barrel with a 12 twist . Both My Magnum rifles happen to have 10 twist ,and I am vey pleased that my 270 Weatherby mag can shoot 3 shot groups under 1 inch at 100 yards . I haver never even tried the 170 Grn Berger's in my 270 Mag . I think even a 10 twist is just not fast enough to get the best out of the bullet. When it come time to re barrel, consider that excellent caliber, with a 9 or even 8 1/2 twist barrel!! Best of luck !!! Lenny
