2 1/2 inch 20ga

[Andrew Frank]

Hope someone can help me. I’m looking for a 2 1/2 inch 3/4oz 20 gauge load for my 5lb Dickson Boxlock. I have tons of powders and am open to any hulls or wads. Thanks for help!

I have roll crimped some 1/2oz 20 gauge loads with with 13 grains of unique and the hit everything I was aiming at and kicked like a .22. They worked better than they should. You could work that up to 3/4oz.

I just sent a load off to Tom Armbrust for testing. Cheddite 2 1/2" hull (RST'S), Cheddite 209, 14.5gr Unique, CB 1075-20 wad, 3/4oz 7 1/2 lead, star crimp. I will publish results if they test good.
One modification I had to make to the MEC 600jr was using a 1/8" short kit build-up piece to get the adjustment I needed at the crimping station. Shells look pretty.

Thank you, I have a few I extrapolated from other data that I’m getting ready to send off for testing but haven’t yet. I’ll let you know as well after I send them out

Unique is a very good powder. We use it for 20g too. Too bad it's an Alliant powder and hard to find. That said, if you see any for sale in a shop, yard sale, auction, etc, BUY IT!!

I've been shooting more and more Longshot , cheap and easy to find. In my 20s the load below has been good. Had it tested at Precision, use at your own risk!
Cheditte 2 1/2" plastic hulls
Cheditte primers
16.0 gr Longshot
SP-20s wad
7/8 oz 7 1/2 shot
6 pt crimp
Again, tested at Precision at 1183 FPS avg. and 7247 PSI avg.
Busts the clays and dumps quail and doves nicely. Easy to shoot.

Slight variation to Mr. Doty's recipe because of the SP20s wad.

Cheditte 2-1/2" plastic hull
Cheditte 209 (2000) primer
Sporting 20M wad
16gr. Longshot
7/8 oz. shot 7-1/2"s
6 point crimp

Tested at Percision, 1,114 FPS av. velocity. 6,772 PSI av. pressure.

Thank you!

I figured I would need to up the powder a little to 14.5gr because the CB wad is designed for a tapered hull and the wad was a little lose in the Cheddite straight hull. Shot a few today and they broke some long fast angling outgoers. Happy me!!
