Greetings
Between rain & farmers working thier fields around our local range there have not been many opportunities to fire my 414 SM built on my 375SM Frame. But yesterday I did get out and the range was open. The results are from 25 yards ...
22-24.5 grains ACC1680 these were just 5 rounds each and just to be sure all was well.
25.5g 1680 265gc fn seated to 2.015 (second crimp groove) Mild load .70 6 shots
26.5g 1680 (same bullit & Length) .80 7 shots
27.5g 1680 .90 7 shots
28.5g 1680 .90 7 shots
29.5g 1680 .75 7 shots
So far using WOLF Large Pistol Primers there are no pressure signs and Case extraction is easy. WEb expansion at 29.5g is just .001 more than the 24.5g load. No leading in the custom machined .410 1-18 twist barrel.
Next outing I will continue advancing charges at .5 grain increments. The 29.5 load recoiled smartly But no more than my favorite load in the 375SM setup with a 255g bullet. Not sure how long before that will happen.

w! If that .90 means .90 inches for the spread, I think you've got a winner!

Sounds like you're getting it dialed in, for sure.
That grouping is sure a WHOLE lot better than I could do, too.

Thanks for the info.
