For you A&H owners, I broke the .209 nipple off mine while removing the breach plug a year ago and figured I was out of business but I found this company on the Internet and ordered a replacement. I works well and is much stronger than the original. Hope this will help someone else that's had the same problem.

I have the same question as crazeymaez. I have a 420 50 Cal. Best sabot I've found is the Nosler S.H.O.T. 250 Grain/ .451 Diameter,

I tried three different sabots brands and everything else was all over the page at 100 yards, two hundred yards was not even an option, 3 foot patterns. Some were tumbling at 25 yards. Spent over $100 trying to find one that would pattern. I'm not the best shot in the world but I can usually keep it on paper but not with anything I tried but the Nosler S.H.O.T.
I would really like to find a little heaver sabot if anyone has a proven product. The .250 Noslers are reliable but pretty light for heavier game.
I like the A&H, my son has one and it was a shooter too, that's why I bought this one. It is a heavy bugger alright but that keeps the recoil mild during practice. When I shot at game I never feel any recoil so I only worry about it during the warm-up stuff.
After I bought the gun I heard the barrels were made in Spain by a company that makes barrels for CVA too. I was worried about that because I've never been impressed with CVA products but I have yet to hear of anyone with an A&H that reported a bad barrel, if you find the right sabot for it, so I quite worrying about it.
I don't pull the trigger on deer very often anymore (at least on in Utah) but still prefer to chase them with a muzzleloader so I'd appreciate any A&H information the rest of you boys have acquired.
