[QUOTE="PapaSmurff, post: 2784573, member: 118512"] Here is the Quickloads data for the load combination that I’m using. There is no pressure signs whatsoever on the brass, the primers are still rounded on the edges, and bolt lift is still normal. The load shoots great. When all the correct parameters are typed in, it gives me a psi of 69,228. That is around 4-5,000 psi over what I would usually want to load a cartridge up to. However it shoots so good (all the way out to 1,000 yards) and with no visible pressure signs at all I will most likely be staying with this load for the foreseeable future. I had to go up to 62.3 grains charge weight on quickloads to match my real velocity of around 2,790 fps. But my load is 62; .3 grains lower than that. My barrel could be 10-15 fps faster could be the difference here. All in all, fairly close predictions charge weight of 62.3 equalling 69,288 psi. Posting a picture of my quickloads screen for reference. I don’t advise anyone use this load however; it is only deemed safe by me in my firearm. P.S. if I lowered the charge weight to match 2,750 fps with psi about 65,000 there was only a difference of 2.0 grains of charge weight. So it appears that it is slightly over pressured but there certainly aren’t any visible signs of that in my particular rifle. [/QUOTE]
