7 Degree Lead

[Don McDowell]

I am thinking a #3 heavy, single trigger, shotgun butt, in .45-110.

Yes have them put the 7* lead in it.

I have a 7 degree transition/leade combined, and it has definitely done away with paper and lead rings.
it is not however a universal panacea.
greasers shot better right from the getgo, and pp lost the fliers, but groups were not fantastic.
dual diameter pp bullets solved that issue.
the thing is that in front of the case, there is the thickness of the case neck clearance on the bullet, and this tapers away for 0.100 length to nothing.
even 30/1 alloy cannot bump up to fill this area, and the back of the patch is blown off.
my next experiment in this area will either be a 12 or 15 degree transition.
keep safe,
bruce.

I been developing loads for my new .44-75 Ballard chamber in the CPA. Here is the best group I shot out of this rifle so far with a MVA scope mounted on this rifle for working up loads. Yesterday the winds where up really to strong for checking out Ladder test loads so I shot the short range that protected the 150 yards from the wind so I used it instead the 200 yard I normally use.

This load I used 82 gr of 3F Olde Eynsford with a .023" card over the powder compressed .090" with the wad and a 1/8" lube wad made with OZ wax and Vaseline 50/50 and a .023" card under the 505gr Elliptical PP bullet cast with a KAL mould at 1/16 T/L alloy.
This chamber has a 4 degree/1-1/2 degree compound transition into a 1.5 degree lead and it shoots quite well from what I have tested for loads so far. All of the rifles I have from the 12 or 13 degree Brownings and the 45,7,5,4 degree throats they have I find the flatter I go with the compound leads not just the 7 or 4 degree, but the compound combinations the better they shoot the PP and GG bullets. I had two rifles with the 7 degree one is the .44-77 and the other is the .44-90 bn and they shot well but I recut those throats to a 4/1-1/2 degree compound and they shoot better. My .44-100 rem St. has a 4 degree/1.5 degree and it is a fine shooter. The next barrel I will chamber for the .44-77 and it will have a 3 degree/1.5 lead and that barrel will go on a CPA action after I get the reamer made. I'm just not sure yet if that Case will clear the hammer on the CPA because of the large diameter case head that cartridge has.
I will not recommend this type of lead to anyone simply because if they cant get a load to shoot for some reason that they will blame the chamber. It's not just the chamber lead that will make these black powder rifles shoot well. It's a combination of several things with just the chamber design, bullets used and barrel specs. that make these rifles work well.
