Re: 257 AM stikes again, HARD!!!
A longer barrel would certainly offer more ballistic performance but the reason I decided to go with the 35" pipe is so that it could be more directly compared to traditional 50 BMG rifles which will have 30-36" barrels in most civilian offered rifles. Some are offered with extremely short barrels but in my opinion these are not viable long range tools.
I want to see how the 510 AM matches up against the 50 BMG in similiar length barrels. If I put a 45" barrel on this beast, it would certainly produce better velocity, especially with 20N29 and the heavies.
Still there are those out there that would claim the only reason for the higher velocity is the unusually long barrel and not the design of the cartridge.
I want to see what it will do head to head with the BMG and let the chips fall where they may. At least it will be a fair comparison between the two.
Also, the AR-50 is not a good option for a +40" barrel in my opinion. 35" is abotu what I feel should be max length for this receiver and more importantly, stock design.
