Shortly after H&R was moving to a new plant (sound familiar?) and stopped production of that rifle for awhile. The ones I could find where way to expensive, so I waited.
Two weeks ago my FFL dealer called me for a pick-up of my new rifle.
I had already ordered all the components, mold and a variety pack of 50 cal cast from Matt’s Bullets. I can only speak for the 50 cal but Matt makes a superior product at an inexpensive price.

I shot a few of his wide met plated gas checked 460gr over 9gr of unique. Which made a nice pleasant experience for both myself and daughter and still punched through a 12in oak stump.
Next I cast 20 rounds from the 440gr Lee mould. Loaded up 10 with the same 9gr of unique and after adjusting the sights shot 4 rounds into a 3/4 inch group center to center at 30yds. With that same load I shot through six milk jugs of water nearly straight and it still buried itself at least 8in into the wood and dirt berm.
Much more to come!!! Lots of fun, this rifle is.
, but I can say that it is one of the first places I look when developing a load. 
) that's laying around. In a pinch, you could even 'nest' sabots, or fill-in the cavity with hot-glue or something, and use .30 or .22 caliber projectiles.
