RE: New Bullet Design
Done Deal.
I don't have one of those 20mm cases necked down to 7mm, but I do have a .243. My 7mm's are much more docile.
I am building a new 7mm wildcat right now. 300 WM case, .284 length neck, 30 degree shoulder at .493. Objective is 175 gr @ 3100 fps. I'm trying a Montana Rifleman barrel @26 inches in stainless with 9 1/2 twist. I was going to mount it on a claw extractor Mod 70 action, but I think I am going to go with a Rem Mod 700. Have a great gunsmith- George Vais.
Building it to replace my .338. Doctor says I can't shoot anything with that much recoil any longer because I have a detached vitrious in my right eye. Love to shoot the .338 but after shooting about 30 rounds a couple of weeks ago, I felt like I had a concussion. Doc says strong impact ( or jarring) to the head or face is not a good idea.
