My 22 lr version is very good however very particular to a certain position
of screw tightening on forearm, I've read that some use a rubber washer
under forearm screw.
I own a newer H and R handi rifle in 223 I consistently get 5/8 inch groups with my hand loads and this is with 55 grain fmj. I would guess that it would shoot a bit better groups with a premium bullet. However I do believe the rifle will out shoot me. I love the simplicity of the single shot rifle it is the only single shot I own. I would not hesitate to recommend one of these little rifles to my friends. One thing about a single shot, it makes me want to take the time to get that first shot just right. Makes me practice what the Corps taught me. LOL!!
