I obtained some .358 caliber 200 grain, Barnes Triple Shock bullets. (Talk about expensive)
SO I figured I would try a few in my finicky Ruger M77MKII All Weather 350 Remington Magnum. It is hard to obtain good groups with this rifle.
Unfortunately I was using some CCI-200 primers from 1973. They are not very good, but what the heck....
Here are some experiments with:
53.0 grain of BENCHMARK
57.0 grains of Reloader 10x
63.0 grains of Reloader 15
The loads and velocity is listed on the photo...
This rifle likes to shoot 3 shots together and then throw two out...
At least I shoot 5 shot groups.
