6BR load tuning

[BCP1980]

New to me panda action McMilian stock, new barrel 12 twist. Below is a picture of todays testing…..I’m starting with the 3 charge weights that showed most promise when fire forming brass. All these were shot with once fired brass. Charge weights are listed on left side and L.E. Wilson seating die settings are across the top…..I’m still learning but 31.7g looks to be my charge weight and currently am liking 04 (+.011 past touch) as seating die settings, but probably need to test that charge weight backing away from the lands more as well as the load at 32 grains. My thinking is as it warms up looks like the 31.7 grains charge weight might stay in tune where the 32 grain charge weight might go out of tune.

Any suggestions is appreciated.
Thanks,
Brandon

My most accurate load for my 6br lrpv savage is with n135 32.5 gr .05 jamed with a 68gr custom fbhp.. It Shoots in the.1s and 2s have shoot my best 5 shot 100yd group ever measuring .077

31.7 is looking good, I'm curious how the target would look at 05-07 in .001 increments

I’d do one more seating depth increment past the 04 setting. Powder between 31.7 and 32 looks good. Nicely done!

BTW get you some 80 gr Bergers to try. N135 will work fine

Thanks you, I will give your suggestion a try tomorrow or Friday depending on weather.

Thanks for the reply, I have some 80 and that will be my next work up…..I shot some of them and the 68’s while fire forming to try to find a starting place for development of both so they will be next.

Try 31.4 and 32 at 007 seating depth.

The 04 at 32.0 is round. I like round. I would take the 32.0 start at .025in the lands and start backing out .002 at a time. The 32.7 shows vertical.
