Re: 300 Weatherby or 340 Weatherby
I'm not recoil shy. But to be frankly honest, I"ve shot 308s in M1As for a number of years. Shoot one with 168s and 180s for 2 weeks+ at Camp Perry and even the 308 gets on my nerves.
Its why I use a brake when I can. No need in getting hit harder than you have to. Plus that retinal connection in your only 2 issued eyes is pretty valuable to me. I'd rather use the sissy brake and shoot more and rest a bit easier.
End answer-- you put in Elk, and out to long yardage. 340 no question.
Get as close as you can, but utilize your skills as needed.
