I found a Ruger Mark II 7 MM Mag looks nice $599 and has a real wood stock. The barrel is only 24”

My Winchester has a 26” barrel but has a synthetic stock “I don’t like synthetic”.

What difference will the 2” shorter barrel make on shooting long distance? I want to take full advantage of the 7 mag potential.

I can still get 3100 fps with 162 gr Hornady's with my handloads and a 24" barrel. Two inches MIGHT give you an extra 25-30 fps. Might not. I see bigger differences between guns with the same length barrels than the slight difference 2" makes in barrel length. In fact a gun with a fast 24" barrel could easily shoot faster than another gun with a 26" barrrel. I've seen as much as 130 fps difference between guns with the same length barrels. 25 to 50 fps difference is very common.

Mine are all 26" barrels. But if you locate a formular that will compute to a given velocity, my 26' barrls shoot 145 gr. BT's @ around 3300's fps.. One of them has almost a 100 fps slower barrel for no apparent reason. So just that you know, different barrels shoot differently in terms of velcoity and accuracy, not too mention which bullet they like to eat.

Gona be a earskaplittin-loud-en-boomer with only 24" barrel, and will probably wash the rifling at the muzzle out with all the burning powder at that point. Al
