I bought a second hand Ruger 77/22 in 22 K Hornet a few weeks ago to replace my CZ 527 that I had rebarreled to the new 17 Hornady Hornet. The wee Ruger is wood stock and blued. It has not taken that long to find a load for it. Was very lucky that it seems to go quite well with one of the CZ's loads.
The load is 6.4 grains of AP100, CCI small Pistol primer, 225107 gas check made by NOE with a 2 ply beer can gas check lubed with White label Carnauba Red to a total weight of 38.2 grains of air cooled wheel weight doing 2340fps. It seems to group about 1.4'' at 100 yds if I keep the bore reasonably clean.
Took rifle for it's first outing thursday evening and shot 46 rabbits with 48 shots at ranges from 55yds to 147 yds measured with range finder. I was very happy with the wee Ruger as have heard some horror storys about some of them. But this one is definetly a keeper. the 1st photo is about 20 rabbits from the 1st spot I went to.
I will be looking at other loads in time, but we are off to a good start.
Cheers Euan.
