I increased the OAL a lot and it seems to shoot fairly well again. I had groups from 3/8"-3/4" but I do think the 3/4" groups could have been affected by the wind gusts a little. It wasn't real windy but if it makes 1/4" difference it is the difference between a good group and a so so group. My last groups were the best when it was nearly calm.

I am still .090" off the lands even at the greatly increased OAL and there is only .060" of the bullet gripping the case. The bullet is deeper than that but with the boat tail bullet there is a portion that doesn't contact the neck. Is this too little?

Another thing I thought of, could a gunsmith cut the chamber deeper to get the freebore somewhat back to normal or would this cost enough that I should just get a new barrel?
