Re: M40 A1 chambered in 7mm Rem Mag advice
I think it would make a great LR rig. I have hunted and shot the 7mmRM for a number of years now. My first rifle in this caliber was a Sendero and I shot the barrel slap outta it. I shot the 150gr Ballistic Tip almost exclusively and never shot past 500yds. That was just MY personal limit, not the rifle/cartridge.
I got a .300 WinMag during this same time and shot it quite a bit also. Never got past the 180gr projectile though, recoil was a bit tooo much for me, even in the Sendero. I decided the Big Seven would do anything that I needed done and nothing around here (animals) appeared to be getting immune to it.
I recently traded that ole Sendero and got a 700P, also in the 7mmRM. I haven't even shot it enough to properly break the barrel in. Been busy with load development for my Savage 110FP .223 and .25-06 Sendero. I did try some 150gr Scirocco (previously loaded for the Sendero), had to seat the bullet deeper, but they shot sub .5" @ 100yds.
I plan on trying the 154gr SST, 162 AMax, 168/175gr SMK's. Powder's will be RL22, IMR7828 and VVN560. Good luck with your project and keep me posted. Thanks. JohnnyK.
