Try remington 75 grain acutips never had any bother with them and devistating to your quarry a bit expensive @£24 a box but used them for a few years now with excellent results
Anyone recomend a good .22 ammo for the ruger 10/22 I am using C C I subsonics but find the magazines jam on a regular basis. Magazines have been striped and cleaned on a few occasions so I assume they are ok.
