.17 hhh
I just got back from shooting the .17HHH with a little tweaking, it should be a real shooter. It started life as a H&R SB2 frame, with a rechambered .17hmr barrel. The first two shots of the last three groups were withing 1/4" and the third shot opened the groups up to 1 1/4". I really found out that I am not man enough to shoot for groups with an 8 lb. trigger on a 8 lb. rifle. I am confident that after a forend bedding, trigger job, or a small port-a-power to pull the trigger, it will be a 1/2-3/4" groups with factory ammo, and who knows with hand loads. The worst part is that it was raining, and the private range, I used was half way between my folks and 40 acres of grass rats.
FWI , I have less than $200 in this gun, less reamer. measurement at pressure ring measurement at shoulder measurement at neck New round .295 .2925 .193 Once fired .2986 .2955 .1955 PTG reamer Last edited by moorepower; 03-12-2012 at 05:25 PM. Reason: Added brass measurment |
