James,
In my testing of my 375 Allen Magnum which has roughly 10-12 grains more capacity then the 375 Chey Tac, I would have to say that if we had the right bullets it would be a better choice then the 338 AM. With the bullets we have access to, basically the 350 gr SMK that are affordable anyway, it will match the 338 AM in velocity at 3300 fps. The BC of the 350 gr and 300 gr SMK are both said to be exactly the same at 0.780. In my testing the 300 gr SMK is roughly .800 out of the 338 AM and the 350 gr SMK closer to 0.770 but very close. Basically, out to a mile or so, they are pretty much ballistic twins but the 375 has a higher kenetic energy payload.
If we could get a lead core, aluminum tipped 375 bullet with a BC in the .9 range, it would truely be an amazing machine. Pretty **** impressive as it is now. Well, actually amazingly impressive, I am just numbed to the performance having played with the 338 AM so much.
The barrel life on the 375 would be far superior as well. I have word from several bullet makers that there will be more lead core 375 bullets coming out soon for this type of use so when that happens it will be hard to pic one over the other.
As far as the 50 BMG, other then kenetic energy, it does not compare at all to either the 338 or the 375 on the Chey tac case with the right bullets. Windage it does pretty good but bullet drop is MUCH more then the smaller rounds.
ANd for all the fuss, and rifle weight and cost of bullets and powder, I would just as soon have the ballistic performance in a portable rifle.
