[QUOTE="Hoss50, post: 1935779, member: 109801"] I went to the range yesterday to run some loads with H1000 through the rifle with the 131gr. I didn't have any starting data so I looked at several loads for 115-120gr bullets and backed the booke number down. Most of the loads showed about 68-70gr as start points so I backed my starting load down to 66gr. I loaded 1 gr at a time high up to about 73gr. I only made it to 70gr before I got a noticeable ejector mark on the brass with flat primer. At 69grs though I got this group so I think with a little tuning this will be good. This data is for MY rifle. Start lower and work up. I would have started lower had I had better data to work with. That is why I am posting numbers, so someone else has a better idea of how to be safe. Other people need to have some place to start. I dont have a velocity yet, but I will borrow a chrono after the load is finished. FYI, my barrel is a SAAMI spec barrel not a custom ream. [/QUOTE]
