40-70ss recipes

[J.B.]

Looking forward to some photos Don. As for loads.. well my boys 40/70 is still very much a 'study in progress'. If you're running 1/16" then I'd keep your bullets around a maximum of 410 grns. I've done very little with pp in this round but loading 80 grns of 2f Swiss behind a 400 grn slick is certainly doable. I've had Acc. make up a gg mould and also tried one of Harlans moulds that allow seating several bands into the rifling but none so far seem to shoot any better than the Lyman Snover. The problem I've had with it is lack of case capacity and leading. The lube grooves in the Snover are almost not existent and with .7" of case taken up with the bullet, then 64 grns or so of Swiss 2f is about as good as it gets. It was a fairly accurate load though despite leading and if you kept on top of it by wiping, then the accuracy could be maintained. Let it build up and it went to pot. If..or should I say ..when I get around to ordering another mould it will likely be similar to the Kidwell/Baco money bullet with several bands reduced but with sufficient lube grooves already into the rifling to stop that initial leading. Obviously not a problem with pp but I haven't gone there yet. I've been using BACo Krag brass without issue and its been good. The 405 Hornady brass is very nice quality but I had the same problem Kurt had and had to reduce the base diameter slightly to fit. I've kept these for paper patch though as its better suited and there is less case capacity due to the thickness. I'd be keen to try that Saeco bullet but it also takes up a lot of capacity.
