I wasn't neccessarily praising the .416 Barrett, and I agree with you whole-heartedly........for myself, a .408 CheyTac, your .338 AM, or the .338 Snipe-Tac would be awesome, and I DO NOT want a heavy .50 BMG action for a hunting rifle.[img]/ubbthreads/images/graemlins/cool.gif[/img] I was merely saying that some of the RIGBY fans might benefit from this new caliber's introduction.
Until now, the only high-BC hunting bullets for the .416 caliber that I know of is GS Custom's HV Bullet but they are in South Africa. They sell a 330gr. .416 cal HV bullet with a BC of .545, which is basically the same as Barnes 400gr. X bullet (.546). I keep thinking that if Barnes took a new 400gr. TSX and put a boat-tail on it, that it would really make even the venerable Rigby a LR killer. Just think about HOW EASY it would be to spot hits/misses at extreme range with a 400gr. bullet.

Think of the .416 Rigby, launching a 400gr. TSX, at 2670fps (106.5gr. RL-22) as a BIG ASS .30-06. [img]/ubbthreads/images/graemlins/grin.gif[/img]
Fifty, is there a bullet out there that is in the 400grn range for the 338 AM or Snipe Tec. Or is there nothing out there, at this time, in that weight. Now if you could get a 400grn bullet going 3000 fps that would be something to see.
Kirby,this is purely a hypothetical question out of curiousity.Ive always heard that the 1-10" twist was best for the 338 300gr bullets,but with a case of this capacity would it be possible to drive the 300 gr bullets even faster with a slower twist barrel with adequate stabilization?

270 AM is based on either a 7mm RUM or 300 RUM case. This rounds case capacity is far to large for it to perform well with 100 gr bullets. Light as I recommend and have tested are 130 gr bullets which will break 3800 fps rather easily.
I do not think the powder charge should be heavier then the actual bullet weight!!!! Thats my definition of "Over Bored"!!!! [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
