Thread: Accuracy expectations

Hmmm - I've got two rifles currently with bushed barrels and they both shoot very nicely, I recall another one since passed to someone else with a bush and it was fine too. Done with care I don't think its gonna necessarily cause an accuracy issue.

From the groups in the pictures it looks to me like your rifle "prefers" a higher node. If you change powders you'll probably find the higher node with maybe less pressure. GRT is a very good tool for analysing this. I can do it for you but need a few input parameters for decent results, you a;ready show COL, we need barrel length, avg velocity of each group and most importantly, the case capacity (filled to exactly square with the case mouth, tapped cafefully to release any bubbles) of water in grains
