Re: Recoil on a 300 Win Mag
My personal experience with "hard-recoiling" rifles/calibers is to re-stock them with a classical design stock, either wood or synthetic. That significantly reduced felt recoil. I'm not particularly recoil sensitive, but heavy recoil from a rifle or cartridge that does not produce such recoil is definitely noticeable to me and I make any/all corrections to eliminate it. Two examples of what I'm talking about:
First an older 300 WM that punished my shoulder. I ended up selling that rifle off to my brother-in-law (I don't like him much), and replaced it with a 26" barreled Ruger #1 with a classic stock. I shot the rifle for years with only moderate recoil; Second, I routinely shoot a 375 H&H, with bullets from 235- to 300-gr (this cartridge is infamous for heavy recoil), and it's not uncommon for me to place three shots @ 100-yds, all touching, and moderate felt recoil. Again, the rifle is stocked with a classic design wood stock.
Too often gun mfrs stock their rifles with "modern" or "trendy" stylish stocks. This may be great when shooting a .223 Rem, but have no place when shooting a large case capacity cartridge from 7mm on up.
Regarding one or two shots not being a big deal, possibly.
But if you develop a flinch when practicing due to harsh recoil, what do you think you'll do when making that "one or two shots"? I read accounts where hunters in Africa, armed with .460 Weatherbys have completely missed an elephant at 50-yds or less!
I've also noted that when I use slower/slowest burning powders, especially with heavy bullets, the felt recoil is altered from a 'punch' to a 'shove'. This may or may not be helpful in your situation as you don't mention your load info.
