SAUM’s Share yours from Hunting or Comp. Pics Heavy !!

Were you @ 2935 with 62grs of Retumbo? Pressure?
Yes. 2935 62 gr. Here is a pic of the brass at 62 gr. Its hard to see in the pic, but very slight ejector mark by the mm seen with the magnifying glass. I figure 61 would be better. I should also mention I shoot suppressed.

IMO you have room to go on that piece of brass. The primer is still well rounded.

This is brand new brass right? If so you will probably need to back it off on 2nd firing. I stopped around 60 if I remember correctly on new brass in my rifle. Also you should gain 50-100fps after around 100 rounds down your new tube.

Yes new never fired brass. I will FL size (shoulder bump .002 - .003) but I would think the brass is a touch bigger on the 2nd firing so the pressure is a touch lower right?

Not necessarily less pressure. A lot of energy is going into fully fireforming it, when fully fireformed (2nd or 3rd firing) you will get a better read on if you are at true max. I think you are safe to try 61 again and see. I personally would not go 62. You do have a little less bearing surface with the 156's versus the 153.5's I am shooting, so that will help.

I can get you my exact load with my rifle if you would like.

Thanks PH. I am always learning something new. I appreciate the advice from all in this group. I will report back in a few weeks.
