Development of PP loads for the .44-77.

[J.B.]

Now you guys are just showing off ! Two hundred yard ranges in your back yard and no visits from the tactical storm troopers when you do practice. Man... that would be magic. Jim ..given you've barely had the rifle a week... I'd say you are well ahead of the game already. Interesting your observations with the 50/110 brass as I managed to get 'one' example at the Quigley last year as it was all they had left between orders and hadnt made up any more. I was using gg bullets and managed to have it chamber without much issue. I know our rifles were done with different reamers but the only problem I had was the 'punched' rim that they have was a little proud for the block. A couple of runs on some fine grade paper had it fitting snugly. I do flare my cases...just the barest amount ( not easy when your cases can vary up to .008" in length I'll add ) but noticed from the get go that too generous a flare.. meant the cases grabbed on chambering. Outside neck diameter can go up to .4675 to .468... just ..but at .469 they grab. The neck wall on the one example I have is coming up at .0115" whilst most of the Jamison I have hovers around .009 or so. Its great to have these snug dimensions in a chamber and just adds to the quality of the product we buy and certainly helps preserve these cases..but it doesn't lend itself to wide variations. I have two batches of RMC brass I purchased a few years back and one runs .014" necks...and the latter at .011". The former lend themselves to that Brooks .431/.432" pp Sharps mould I mentioned ..without any neck sizing. My experience to date is that at .469".. the cases almost stopped dead in the chamber before going home...but one thou back and in they slide...with a hint of touching all the way around.
