Re: 338 300 gr A-Max Bullets
[ QUOTE ]
I just tested a prototype 270 solid bullet for a company in my 338 AM. IT was similiar to the LRB J40 bullet. BC measured out to be around .860 and I was able to break 3600 fps with this bullet in a 40" 1-10 barrel.

I know of a guy making a 270 grain solid with a b.c over 1. It requires a 1-7 twist at 3000 fps. The only problem is you have to buy 300 at a time. Thats a lot of bullets to try, just to see if they will stabilize.
