Maybe even Tom Sarvers new 7mm Hulk, based on his 300Hulk, which is a shortened and improved 338LM.
Here's how barrel life works: it goes to hell fast as you approach and pass 3000fps.
A 7mm-08 @ 2650-2700 will get many thousands of rounds
A 284 @ 2850ish will get several thousand
A 7RSAUM @ 3000fps will see ~2000+
A 7WSM @ 3000+fps will see 1500+ (less efficient than 7RSAUM)
And it gets worse from there... </div></div>
Not sure what your basing the last statement from, I have right at 2500 rounds thru my 7RM with the 162 gr. Amax at 3,100 with no hint of accuracy going away. </div></div>
Isn't that fantastic barrel life for a 7RM? I don't doubt you, but I gotta admit I can't understand how a 7WSM can eat a barrel in ~1500-2000 rounds @ 3050fps, meanwhile an even higher capacity cartridge lasts longer?
Is well over 2500 typical of 7RM? I know there's a lot of variables controlling barrel life, but in general, more powder = more velocity = less barrel life.
