Formed up another 15 pieces of brass and I ran them all through with just a little bit of dry lube on the necks and I didn't have a single dent and sizing was smooth and fast.

Rich and Rhian, Keep up the good work! Looking forward to the test results, I have optimistic expectations. Im going to be ready to build either a Sherman alone or both that and an SS this year possibly. great having you guys share this data.

Thanks Andy.....I'm still hoping to share a hole in a bear if my smith gets my rifle together. I'm fast running out of daylight with season ending in my unit the end of May.......Rich

Re: 6.5 ss final design

So I got the candle lit today, it was interesting to see what came of the 56.3 grains of H4831sc compared to the 6.5 Sherman. The 6.5 SS ran right in the same speed as the 6.5 Sherman and accuracy was there also I did hit some pressure signs at the top end at the 57.5 and 58 gr but not excessive, the 58 grains shot poorly, the 56.3 and 57 looked very good, the bottom shot on the 57gr I reefed the trigger like I had a grudge against but I think it may be a good one to reload and give it a fair shake.

Re: 6.5 ss final design

Darn, I'm so envious I could spit! I've always had excellent accuracy with H4831 in the 6.5 but usually not near top velocity. I think some RL22 and 7828 would really light that thing up! I have about every slow powder made if I ever get my rifle together.......Rich

Re: 6.5 ss final design

Thats really great news Rhian and Rich, Im convinced that a long action I have could be a 6.5 Sherman or 280 version, A short SS now looks a great way to get a great SA new 6.5. I may have to get the SA I have a line on coming sooner now!! Ive got matrix bullets waiting also. Keep up the great work guys!

Re: 6.5 ss final design

I missed the distance you shot the groups at did you say 600?

Just kidding, (I hope!) I am assuming 100 yds.?

What were your velocities or did you not chrono this time?

Thanks
