Shot the 26" 7 prc today. Groups below are at 200 yards and the load is 68.3g retumbo, federal 215 match and 180 hybrids. This barrel has just a crack over 100 rounds on it after today. The below groups were rounds 79,80,81 and then 90,91,92. And we're shooting at 2910fps. 15 rounds later I shot my last 3 of this load at 450 yards with a 2" group. But velocity had jumped up to 2960fps.
68.9 started the day at 2920 and ended at 2975 while also giving a couple clickers.
I'll be backing down to 67.2 or so and working back up to find that 2910 node again. Shoots great but not anything that can't be accomplished with a 7 Saum in my opinion

I'm getting 2982 fps and 4.4 sd and .950 -5 shot group at 200 with 175 hornandy eldx 68.8 h1000 . Want to try retumbo but with 8 lbs of h1000 I'm doing pretty good , 7 prc 22 in carbon form Oregon Mountain rifle in Billings, mt- Lee is awesome and absolutely answers questions

I've posted this quite a bit but I'm at 2975 with the 180 hybrids and n565 ran well above 3050 with both h1000 and n565 without appreciable pressure signs. Mine is on a LA throated long Adg brass. More accurate than I can shoot, love the 7saum
What is your barrel length?
I'll have some info on a 20" 7prc soon, just screwed on my barrel last week. Ive got some blem 180 eldm's and a pound of mag pro I'm gonna burn for break in and then I'll switch over to H1000 and start some load development.

Also have a 7 saum on a model 7 Remington action but can't get full performance out of it in that action/stock combo, another 7sanm is on my list agin
I just bought some 7SAUM ADG brass because of FOMO (fear of missing out). I don't even have a 7SAUM rifle. I like efficient cartridges that will work well in shorter barrels suppressed.
I need to have my parts to the GS in two weeks and still can't make up my mind.
What velocity are you looking to get from what bullet?

I would think you could get more velocity…My 7SS is at 2980, 20",168 gr

Careful with buying powders that you don't know what cartridge you plan to use.
I had some powders left over that were for a specific cartridge that I no longer had and I asked what were some of the best cartridges for those powders and I got chewed out because …who buys powders and doesn't know what cartridge they are for ??? what they couldn't understand was I knew what cartridge they were for when I bought it, but I sold the rifles and Figured why waste 60 pounds of powder. why not buy a cartridge or make a new load for the cartridges i had on hand that would work
