A 300 gr. bullet at 2700 FPS, a 260 or 270 at 3000FPS is pushing the string beyond belief IMO, or their chronograph is heywire or they have an over actitive imagination. I also expect their days of living on this side of the dirt are severaly limited! Yes, I know some folks that claim to load the 375 H&H to such velocities also.. I betcha brass doesn't last long. I would never load my .375 to those spects, to start with it means absolutly nothing in the field, so whats the point.
To say that one of these cartridges (9.3x62, 9.3x64, 375 H&H, 375 Ruger) is better than the other in the killing field or in trajectory is ridiculas and shows a lack of experience, they are all so close to equal that no-one could tell one iota of difference but I'm only baseing that on having used all but the .375 Ruger on DG at one time or the other. I have however built several .375 Rugers, done the load testing on them, and found it to be a wonderful cartridge but it is not the equivelent of the second coming as portrayed in some of these posts.
.............Then go read Gatehouse`s post in the other section (ask the gunwriters), and then tell him that he`s nuts or his chrony is all screwed up. Another 375 Ruger owner posted there, that he also came very close to the 2700 fps figure using the RL17 and a 300 gr bullet.
Perhaps there are a few under-estimations about the RL17/375 Ruger combo? Why is 2700-2725 fps using a 300 gr bullet so unbelievable from a 20" barrel?
300 gr Hornady factory ammo from a 20" Alaskan barrel as I`ve seen written, averages around 2570 fps. My personal results have averaged 2592 fps over my own chrony. #1) Tack on a little faster bore in any given particular Ruger Alaskan rifle. #2) A brand change of 300 gr bullet namely to the Nosler AB, which btw, will have less bearing surface against the bore than does a 300 gr round nosed Hornady. #3) And then for the final pee-azza-resist-aance, let`s add some RL17 into that mix as well.
Perhaps the RL17 can do for the 375 Ruger, what we already know that it does for the 300 WSM.
Don`t think 2700 fps can be achieved? You might want to think that one through again!
