Sorry, life has turned into a marathon. I did my test with the new bi-pod from 50 yards.
Factory Load Test:
Winchester FMJ 147 Gr gave a 1/2\” group with a 1\” flier.
Browning 124 Gr rn FMJ gave a group 3/4\” with a 4 inch flier.
These groups are from hole center to hole center, so you can halve them to find distance from bull at 1/4\” and 3/8\” off target.
Hand Load Test:
I used a COAL that was on my die from last attempt(2.1.15\”) just to see the difference between (small rifle): Winchester #41, Federal Gold Medal #GM205M, CCI #400, and Fiocchi. Here are the results: Winchester: 2\” with 3 1/2\” flier, Federal Gold Medal: 1 1/2\” w/3\” flier, CCI:3/4\” w/2\” flier, Fiocci: 2\” w/2 1/2\” flier.
It appears the CCI primers might be the best of the lot. Every 3 shot group had a flier, so I\’m not too confident that my barrel isn\’t slightly defective. There is an extractor gouge sometimes, and some stove-piping with the rifle. I guess my first issue might be to solve the failures with my 350 legend.
