Well the first loads are now done on the new rockchucker and here they are.They are for my brothers 7mmrm. We are no means the best shots out there but he was pretty happy with the results for the first try. The bolt was a little stiff he said on the 68 gr so looks like the 67 are the best. Might try 66.5 and 67.5. Might try and play with the length a bit yet.Started .050 from the lands. IMR 4831 120 gr ttsx ,fed brass and cci lm primers.I think we did all right for rookies, and he's got all of his eye's and fingers...bonus. The one target that looks like a shot gun is from the bullet hitting the metal grater blade that was pounded in holding the backstop. His factory loads shot about a 2'' group , best his gun ever shot he said and was grinning ear to ear. We went three ways on the chucker kit ,money well spent.
First loads ever.
