If the weather ever gets above 25 I might just hit the range with 5 new duplex loads that I'm playing with and I'll let everyone know what happens.
They are with Reloder 7 and Cartidge with 385 Mos bullets. Starting with 10% and working up to 15% and the reminder with Cart. equals to 52 grains of powder. Might be to light, may need to work up to maybe 58 grains total.....

see you later, Van

Ave 5 shot Velocity over M33 Oehler- 1435fps

Same charged cases as above, but with 400grain
Lyman 410655 Flat nose "sharps design" for hunting load

this is the first duplex load that has shown any promise. I in the past have tried with out much luck to get a duplex load to shoot in any of my 40-65's. This load has shoot very well right around 1 MOA at 100&200 yards. And it seems to be able to do it the last 4 times to the range, so I'm satisfied that this might be my gong match load. Here it is 7 grains of Reloder 7 and 45.5 of Cartridge under a 385 Snover shaped nose Mos bullet, W?W brass and Rem. 2 1/2 primers, very small amount of compression (hardly any) the velocity runs 1311 with a ES of 7 fps.

This is my first post on this site and I'd like to share a 40-65 duplex load that I used about a dozen years ago with good results. I used a 300 grain RCBS plain base bullet sized .410" and seated to crimp on the lower part of the top drive band. All grooves were lubed with the NRA 50/50 alox/beeswax formula. I used 2.5 grains of WW-231 and 48.0 grains of AA-8700. While AA-8700 has been discontinued, I read that WC860 is a good replacement using the same load data. I've since sold my 1875 C. Sharps rifle in 40-65 but my records show good accuracy with the above load.
