So far, I really like the Lee 405 hollow point. I don't run mine through a sizer, I pan lube mine so I am shooting them just as they drop from the mold at .456" (just measures one, unusual) DJ's mold on the other hand drops 'em at .458"/.462" a little out of round, but doesn't seem to hurt anything, both will readily shoot into 1.5" at 75 yards from my gun. If I do an extra bit on my part I can get 4 into 1", but the recoil is enough at 1450 fps or so to keep me from being able to do that with 5 just yet. The Lee 340 grainer is also shooting well in my gun, and it drops at .457". I have not yet slugged my bore or anything so I have no real idea of the relationship of the bullets size to my bores as yet. Also, I am using a mil-surp powder, WC 846. It is quite comparable to BL-C2 and acts just like it in my 30-30. Comparable cannister powders are Hodgdons BL-C2, Accurate Arms 2495, and Winchester 748. these are of course slower than the traditions speed powders for 45-70 (Alliants Reloder 7, IMR 3031, and IMR 4198) but the 45-70 is generally forgiving of burning rates and will give very decent velocities with powders as slow as AA3100 so long as bullets of at least 400 grains are used. Stay with the faster rifle powder for lighter bullets. The slower powders will be dirty (incomplete burning) and will deliver all the recoil the 45-70 is capable of as the charges are going to weigh 50-60 grains. They are capable though of delivering some very accurate groups.
