Trying to make reloading easier.

7prc results

I was just looking at this thread, and noticed something....

Are you getting any pressure signs on these 7prc loads?

I havent loaded for a 7prc personally. But Vihtavuori's load data for 195 bergers in a 7prc is max at 66.8 grains. Often times book loads can be below your true max, but rarely more then say a grain or so, especially on these newer cartridges that have better chamber tolerances.

Your like 6-7 grains above that. You might want to be cautious with that load. That feels way too spicy.

I've been accessing this load for some time now. I have ZERO pressure signs. No slight hard bolt lift, no flattened primers, no head stamp marks. Nada. I love it but don't particularly like the the fact that it"ll rot my barrel in no time. Another guy on here said he did the same powder and bullet and he got pressure at 73.2g if I recall correctly.

Fair enough.

Just figured I would double check.

I had pressure at 72, loading just over 70 and .020 off the lands.

Heavier bolt lift; not bad but noticeable.

Go listen to the Hornady Podcast “your groups are too small” episode 50

Then listen to 52 and 121

You’ll learn about sample size and why 5 shot groups only tell you “how bad a load could potentially be”.

I've been meaning to get back to you on this advice. Just wanted to thank you for the tip. I watched the videos and it was very helpful. Thanks pal.

I've found that good barrels give great accuracy at most every charge. Work up to the speed you want and settle there. Maybe play with seating depth a little. People love to over complicate things.
