    Default 44 Mag loads for 16 inch Rossi M-92 carbine

    Still playing with loads from 16 inch ROSSI M-92 44 magnum factory open sights. The 300 MP worked ok but it sure is dirty.
    So far I have not found a load that I really love for this little carbine.

    The only reason the I bought some 300MP powder was that I have been totally unable to find any H-110 or even another can of Lil Gun over the last year. The H-110 that I do have is 30 years old and I only have half a pound.

    The 300MP seems to be in the same general pressure range, but it sure is dirty. In a pistol it makes a HUGE muzzle flash.

    I certainly is not an easy carbine for accuracy loads. I suspect that the barrel is a wee bit over-bored. The chamber is a touch big as well. Probably made by Brazilians on a Monday morning.

    I have been experimenting with 300MP powder because I am running very low on H-110. It seems to be in the same pressure range, but it sure is dirty burning.

    My M92 had a horrible crown. Cleaning that up helped significantly. Can hold 5 inside 4 inches at 100 yds most of the time. That's good enough for what it is in my estimation.

    I slugged the bore. The lands are .425 and the grooves are .430....

    Here are the bullets I have most been playing with. I have some non-gas checked 250 grain cast slugs that are .432 in diameter. I might try those next.
