Gunsmithing How come...

[leagle2]

you don't see any wildcats (that I know) of, based on the 7mm Rem Mag? The quick answer, I know, usually is that it is duplicated with a "standard" round. What .243 round is out there that would that would duplicate a 7mag necked down to .243 and twisted to shoot 105/108gr bullets? Other than a short barrel life and people's misguided concerns about "belted" brass what down sides would I run into? Thanks for any in put.

Maybe something along the lines of the 6mm "Crusader" with 105's in the high 3's, close to 4k fps?

I think it gets to 1000y for about 7 MOA

Re: How come...

244 Belted Rimless Magnum H&H is 6mm on a 300 H&H case. You could do the same on a 7mm Rem Mag case. Finding a bullet that would hold together at maximum load may be a problem. Have you considered .264 Winchester magnum?

Good luck

Re: How come...

Sierra and JBM balistic programs call BS as well. 105VLD's at 4k fps, 1k yard dope 13 to 14 MOA at best....................................if the bullet holds up that is

i just assumed he forgot the 1 before the 7. without running the numbers, i could see 17 moa to 1k. i think that it was around 18-19 moa to 1k that i figured i could get with a 155 scenar out of a 300 win mag

Bullets spinning apart at those speeds is the biggest problem!
