Jeff,
J: It's a 1-14 twist, and yes I'm interested in as much data as possible. Since my barrel has a .410 bore, I'd like to try some 41 mag. bullets. Your thoughts on this?
F: The only 41 pistol bullet I ever tried in my rifles was the H&G 256.410.
This bullet never did shoot over any load I tried except very light loads intended for indoor practice.
Your 14 twist should stabilize anything you can stand to shoot in the short gun.
The Lyman-Ideal number for the 405 Winchester bullet is 412263. This is a 300 grain round nose. The load mentioned previously, 33 gr Data 4197 and 15 gr grits is one of the best loads I have worked up. Fairly fast, powerful and accurate. I works with both the 300 gr Lyman and the 320 gr NEI bullet I have.
The bullet is critical I think. I had NEI make my 320 gr item by dipping their 285 gr flat nose Bevel Base design a little further into the mold block, making it heavier. Then I carefully removed the BB by hand here at my place.
I have also fired up to 42 grains WW748 under the 300 gr bullets. With and without filler.
Velocity was never a really high priority for me for the most part. I wanted consistent speeds for long range shooting and used lots of reduced loads using IMR 4227 and vairous 350 - 380 grain bullets. Usually 20 to 23 grains worked best for me with some kind of filler. I have used T/P filler and inert cerials successfully in the 40/65.
Non-fillered loads with nearly full cases of medium-burning powders never filled the bill for me. They were usually too powderful for the long range game; providing excessive recoil, or too fast and thus drifting too much in the changing conditions of the Buffalo Gun long range shooting I am interested in.
What kind of shooting is your short gun used for?
Good afternoon,
Forrest
