Hello all, 1st post for me just found this forum the other day, anyhow I have a M700 that started life as a BDL 22-250 left hand. I have had the gun re-barreld with a shilen medium contour 26" barrel chambered in 260 rem and with a 1:9 twist. the action has been epoxy bedded, the barrel has also been bedded and free floated and the relief at the tip of the stock removed which helped some. the bolt face has been trued and lugs lapped. my best hand loads are 47.0 of Reloader 19 with GM210Match primer with OAL of 2.820" which is about .007 off the throat. Here is the problem, with a cold barrel my 3 shot group will always be 2 in the same hole and the 3rd shot about 1 inch out. the second and subsequent groups will be very tiny and better the hotter the barrel gets, for example yesterday I shot a .360" group with my 6th - 3 shot group all with a hot barrel are way under .500" groups. what is going on with this? I have never heard of a rifle that shoots better the hotter it gets. I also thought maybe I was over-doing it with cleaning and there is no difference however I have stopped cleaning after each range session, currently I have about 40 rounds since the last cleaning and notice no changes. I dont think its my components which B-tips are not matchkings but I still shoot great groups after the barrel heats up. I also check concentricity and keep it within .002". Can anyone help me?
