[QUOTE="MSLRHunter, post: 437762, member: 20566"] I have a Rem.700 5R in 300 winmag that I am working up some loads with. Today, I was shooting 210 Bergers, cci 250 primers, 2x fired Winchester brass, and varying loads of Retumbo. The max load of Retumbo for this bullet is 77.2 according to the folks at Berger. After shooting, I noticed that the primers with the 77.0 charge were flattened, however there was no cratering on the primer, and I didn't notice a sticky bolt lift. Also there were no ejector marks on the case. So, if this is all the pressure signs I have, should I slowly work up to the max of 77.2? Or is this where I should stop? [/QUOTE]
