Eric.
I never got the accuracy shooting the MB like your using in the .19 twist .44-77. It does OK, not great, in the larger capacity .44-90 BN with the 19 twist but in the smaller .44-77 it falls short. I have that bullet in PP and GG.
Send me your mailing address through the PM here and the next time I start the lead pot I will cast you some what I use in my .44-77. Right now I'm working on my Daughters loads getting them to shoot at the Q so it might be a while before I will cast some.

I use these for everything and they will shoot as far as your sights have elevation. I don't shoot matches with my Hartford and I don't use a tang sight, it's a hunting rifle only for me.
I played with this rifle at the Q and Baker as well as other places where I can shoot long range to see what it can do and I once had the tang sight on it and this rifle is very accurate. Using the Lawrence and Hartford front sight I made 18 consecutive shots on the 800 yard buff at the Q during the week days on a calm early morning. Sometimes I ask myself why don't you use it for the gong or silhouette shoots.
I use this bullet and a tapered Gibbs from a mould made by KAL up in Canada. The Gibbs mould drops a bad bullet but cleaning it up it does well. I think a bullet from a good mould it would also be very good. I would send you some of those also but it is one of 3 moulds missing from my drawer I loaned out and forgot to whom and they never sent it back home.
