Re: .243 for less recoil?
I feel your pain. I just sold my .270 a couple weeks back. With scope the whole package weighed in at 7.2 pounds and was the most uncomfortable rifle to shoot. It kicked worse than my featherweight .300 WSM. Thank goodness my oldest son claimed it a few years back and he was the only one who hunted with it.
Everyone who would shoot would start out saying .270's don't kick...for some reason they never wanted to fire two shots in a row with mine and normally ended up saying HOLY $hit that things kicks worse than a mule.
Anyhow, what helped most was the fact I loaded some 110 gr bullets for deer and pig hunting here in Texas. They worked great. I had 130 gr loads for mule deer & elk, not that I ever got to hunt elk with it.
My oldest bought his first rifle and down sized to a .243 and loves it.
As mentioned you might try a brake on the .270 first. My .270 barrel was so thin you really couldn't put a brake on it so I had it mag-na-ported. Biggest waist of money I ever spent. I like my brakes flush and seamless with the barrel, so that's why I couldn't put a brake on it.
Best of luck!
Distance is not an issue, but the wind will make it interesting!
