I finished what I will call breaking in Dolemite by shooting 50 shots with 300 grain XTPs. I had some 300 grain Parker match hunters so I sized eight of them and gave them a spin. The first three fit a little loose so I knurled them. I shot them yesterday right before dark. The first two shots were pretty much in the same hole. The third was at dark-opened the group up to 1/2 inch.
I had time to squeeze in the other five shots this afternoon. Shots 1-4 were in the .2s. 2,3,4 were .1s, pretty much in the same hole. 5 opened the group up to .6. The last shot felt good but I could not see the red dot on the target.
What was interesting is that my velocity jumped substantially today. Shot 1 - 2965
Shot 2- 3012
Shot 3- 3026
Shot 4- 3025
Shot 5 -3024
Yesterday my velocity using the same load but with the knurled bullets was 2944, 2926, 2929.
Not really sure why the difference. The bullets seemed to load the same. Shot two today seemed a little loser but not much.
I did notice that the bushing was lose when I pulled the beech plug. Don't know if this could account for the increase.
I have shot less than 20 shots since cleaning the barrel so may be that the barrel is just settling in. I have shot a total of 58 shots so far so the barrel is probably not broken in.
I can't wait to get my adjustable front rest. Using front and rear bags is a pain to get lined up and on target. I am going to dump the rear bag the next time I shoot.
The temp was 88-90 and the humidity is high. Still, I did not have to pause between shots and the barrel did not heat up. All and all, I am pleased with what I am seeing thus far. Nothing like shooting the MLII.
If any of you are on the fence about the Labradar, go ahead and jump if set up time matters to you. It takes me longer to set my bags up than the Labradar. Out of the 58 shots I have only failed to read 2 due to muzzle blast from the brake being too close.
