Pulldown 8208 - Powder Charge Window in a 6PPC?

[Sleepyhollow]

yep that’ll be interesting to see.
if I remember right 3250 was the place a lot of folks shot the stuff

3350 is my sweet spot with 8208. 3250 up to around 3375 it'll flat shoot.

Tested again today. Happy to report I have no pressure signs all the way up to 30.6 grains. I’m good to go.

AO73 with 67gr boattails right at 30gr. Maybe 29.8-30.2 gr. The rifle will tell you. It's still a finest accuracy at one number powder depending on the day. If group is tubby it wants more, if anything spits out of group it wants less. Good powder. Hope this helps.

Thanks so much. I’ll give that a go. You confirm what I’ve discussed with another well respected shooter.

That Nader guy is a pretty well respected shooter too.

That was my point! I've been to a match or two where that Nader guy kicked everyone's ass.

I might be on to something here. New 13.5 twist Krieger barrel. 268 neck, 264 bushing. Charges thrown and not weighed. Did a boresight to get it on paper. Shot a couple down low for break in. Cleaned, shot a fouler, then the two five shot groups shown. Powder charge and seating depth were chosen because that combo showed good potential in a different gun with a different chamber. Still no chrono numbers. I'll get there. The next step is to run a Boyer test combining seating and powder charge changes in and around where I started from. I'm encouraged. Thanks for the help Joel.

A skosh more powder would hopefully suck that half bullet of vertical out

Awesome!
