[QUOTE="D.Camilleri, post: 1184183, member: 2567"] For anyone else with a somewhat factory gun, I am using a factory magazine box at least this week. I am seating bullets to just clear which is 3.670. I still have a jump of around .140 to the lands. I tried loading to a deeper seating depth and nothing about it was good. More pressure and less accuracy. I have a load with the 300 grain Berger OTM that is 90 grains of H-1000, cci 250 primers and it nets 2775. I started playing with the 300 grain accubond as a fight stopper round for mad grizzly bears. 100 gr of RL33 got me 2820, 101 gr 2857, 102, 2895, no hard bolt lift or extractor marks. Remmy brass. Now that I have started with a very clean bore, I need to find how many fouling shots this barrel takes to get it to settle down. I shot around 13 rounds yesterday and the last 3 were Bergers and they were touching. But I don't know if this is due to a thoroughly warmed up barrel or not. I need good cold bore numbers. I think I will shoot again without cleaning and see what the results are. As soon as I am confident of my 100 yard groups, I will take it out to 700. [/QUOTE]
