Hey guys,

I have a new 270 win. X bolt and I had previously posted about powder and bullet selections with some great feedback. I have decided to start with the 140 grain Accubond and H4831sc and H1000 for powders. The gun has a 22" barrel, not sure how much that affects things, and my question is, Federal 210's or 215's? Guys are all over the board on this and with max powder charges in the upper 50's and lower 60's it seems, according to some, that I'm on the edge of switching to the 215's? I know the real test is shooting both but I just wanted to know the thoughts of others on this, thanks.

There is no reason at all to go to 215's. but if you want to back it off a grain and try it.

If you're worried about velocity with your 22" barrel you might gain more by a little faster powder than a magnum primer. that too would be minor.

Stay thirsty my friends

Thanks 440. Do you think H1000 is too slow for my 22" tube? I had great luck with this powder in 25-06 with a 24" tube. I guess my thought was maybe the 215 would ensure complete powder burn in the "shorter" barrel?

H1000 is way too slow for a 270 to give you good velocities. You don't need a magnum primer either. Crack open a few reloading manuals and go from there.

accubond · Dec 18, 2014

I would typically agree but it worked incredibly well in my 25-06 and the Hodgdon manual got their best velocity with a 140 grain bullet in 270 win with H1000? Although not as commonly used as any of the 4350's and 4831's I do think H1000 is a legit candidate for the 270 win. Call me crazy but right now I'm thinking about loading up some 4831 with the 210's and using 215's with the H1000. I will post my results, good or bad, when I'm done. Might be a while though living in Minnesota. I research and load in the winter and shoot in the spring. Thanks for the feedback guys.

My 270's have 24" barrels and I've found H4831 hard to beat. with a 22" take 60 fps or so off.

I'm sure H1000 will work but I can't imagine it as the best choice for your application.

Stay thirsty my friends

LAST EDITED ON Dec-18-14 AT 12:58PM (MST)[p]I bought my wife a Mossberg ATR 270 win last yr i use 54.0 grns of reloader 17 cci 250 primer and a 130 grain nosler accubond it is very accurate with load,it is getting 3048.5 average mv fps if hat helps you out any

Zeke · Dec 18, 2014

If you feel a "need" to use magnum primers, use one of the milder ones (like Rem 9 1/2 M) rather than jumping all the way up to the 215's.

There's not a good load out there where I would personally feel a need for a magnum primer in a 270 Win.

Beyond that, do what you want.

Thank you all for the feedback. After reading your thoughts I think I will just tinker with the H4831sc (and possibly RL 17 and 19) and the 210's. If I can't find something to my liking with that then I will experiment with the H1000. Thanks again gentleman.

No need for 215. Use a 210 and h1000 will work. If it doesn't give you the speed your after then I'd try 4831 or RL19 or RL22.

Check your lands measurement at mag length. If you can touch I'd start 010 off the lands. If not start at mag length.

accubond · Dec 18, 2014

Thanks 805. Is the distance off the lands from experience with the Accubond or just your typical rule of thumb? I'm asking because I would generally start where you're saying but a gentleman with Nosler told me to start 30 off.

Cahunter805 · Dec 18, 2014

Just my general rule of thumb for bullets like the accubonds. You can always seat them deeper after initial testing. My guess is your magazine will limit you in the browning.

trophyhunter · Dec 20, 2014

Well we use the 210's for everything from Win 270 to 300WBY Mag. We like a hot fire to ignight the powder in all conditions. Wet ammo during a down poar included. The 210's are sealed making them water resistant right? We have never ever considered the 215's. When we started loading years ago there were no 215's. Got 10,000- 210's won't be changing anytime soon

210s for 270. I've had better luck with the IMR version of 4831. The H version version was always slow. You can't use the same data for the two.

accubond · Dec 21, 2014

Thanks guys. Are the the IMR versions of powder as good as the H versions in relation to temperature sensitivity?

440sixpack · Dec 21, 2014

Don't worry about temperature on powders in this class they're all fine.

Maybe when you get to powders like H870, but I've seen it used below zero with no problems.

Stay thirsty my friends

Pre64 · Dec 21, 2014

We can all suggest loads that work great in our rifles. There is no telling what will work in yours. The difference between powder A and powder B can turn a so so rifle into a tack driver. That's the fun and the frustration. When you hit the right powder you will know. Have fun.

accubond · Dec 21, 2014

I hear ya 64. I look forward to start tinkering and greatly appreciate everyone's feedback. I will be starting on a new 225 grain load for my 338 RUM too so I will have a lot of bench time come spring. I've had worse problems

Here in Kali two years ago we switched to the all copper bullets because of the Regs. Nosler E-tips, Nosler most accurate load that we could use in both the 270win. And 30/06 we had to switch to Reloader R22 powder, We used the IMR before the R22, we've used those Fed. 210 primers in everything with good luck for years. We don't bench shoot except to make sure the rifles are zero'd for hunting season.
