I shoot mostly PB score. Wondering if a 21" barrel with more weight in the stock vs. 23" barrel would help
With tracking and muzzel jump. 3" forearm and 18" twist is OK for the torque
Txdan, your question about a rifle's balance point is a good one, and one I have wondered about myself.
The reason is that my LV 6PPC has a just broken-in 23" barrel and the rifle balances just over two inches in front of the action face. With a Kelbly SPG stocks built for free recoil it seems a bit front-heavy to me. I intend to shoot it in a match soon and wonder if the front-weight bias will prevent it from being competitive. I still have some time to have the barrel shortened, so I'm looking for the same answer you are!
I watched my good friend Mark Luksic shoot a group at Reidsville. The fellow that owned the spotting scope was looking with it so I was watching Mark and waiting on the scope. Mark set in shooting his group and the rifle slid straight back on some shots and came completely out of the rear bag on others. I was planning on telling him that his rifle was flying around but the group he shot was a smaller than the usual "one something" and ended up being small group for the agg. Don't really know what happened there but it seems that whatever the rifle does is not related to what the bullet does.
