I have taken my (4) Ruger #1 rifles to the range and been pleased; 223, #1V 223, 270, and 7mmRM.
The 270 has not killed anything yet. But the other 3 have killed a boat load.

I have (6) SKS, (1) AK, and (1) 1903 Turkish Mauser I converted to 7.62x39mm [single shot].
One of the SKS rifles went to the range. The rest of them I have never shot.
I do not consider that cartridge adequate for deer, where I hunt over sage brush.
