I am trying to get a good load for my rra predator pursuit rifle. I loaded up three different bullet weights to see what it liked the best. I loaded up a hornady 60gr vmax, sierra 69gr SMK, and a hornady 75 hpbt. With the 60gr vmax I was seating the bullet to 2.260 and out of 25 all of them were between 2.257 and 2.260. When I switced to the 69gr I was getting between 2.248 and 2.264 I kept trying to adjust the seating and would get to where I was getting 2.260 and I might get two or three at that depth then they would just be all over the place. out of 25 I got only about 8 that were 2.257 and 2.262 the rest were between 2.248 and 2.255. I did notice that with the 25.5 gr of varget I was using that it was just starting to compress the powder. I was thinking that with the bullet being into the powder that this was the cause for the varying OAL? When I loaded up the 75 gr with 23gr of varget I was getting the same thing. This time though it was not a compressed load so that could not be what was making the oal length change on me. With the 75gr I was getting between 2.378 and 2.390 Anyone have experience with this happening with them?
