[QUOTE="Tikkamike, post: 534765, member: 22242"] I finally decided that 91 gr of retumbo seems to be about max after looking at my cases and thinking about the results, not the velocity I wanted but I think in this case its just what I am going to get. which is about 3125 average. Anyway the first 4 shots on this target are the 4 middle ones and the outside 2 naturally are 5 and 6. My barrel never really got warm as I had a nice cool morning and lots of time to let it cool between shots. however there is a certain amount of heat retained each shot so the last 2 being on the outside of the group does not surprise me. This group is not very good although shows promise to me. Again the bullets are 200GR LRX seated .050 off the Lans. I am thinking I will try a group that is .010 further off the Lans and a group .010 closer. and see if the group wants to tighten up or open up or stay the same. I have a sneaking suspicion that one way or the other it is going to tighten up a little. And maybe this rifle is no good for 5-6 shot groups maybe I need to get my info from 3-4 shot groups but I will load 2 more batches of 5 and see what happens. Any and all input wanted.
