SCORRS / Re: Uberti's "Remington NMA Cartridge Conversion", .44WCF...
« Last post by mtmarfield on Yesterday at 11:30:29 PM » Greetings!
My Shooting Buddy gifted me a small tub of bullets cast from his obsolete LEE #90339, a .429" - 208gr Wadcutter; these
were tested to a BHN of 15.
With a "Starting Charge" of 5.2gr of Hodgdon's TITEGroup, CCI #300 caps, and R-P .44-40 brass, I seated these bullets to
an OAL of 1.521", crimping into the uppermost lube groove.
Sorry, no chrono, but average 10yd groups hovered just over one inch, with my best group inside my 1" orange paster. An
offhand, two-hand hold would usually allow this performance at 20yds, but alas...
Similar experiments with a new RCBS #44-200CM, sized to .429" and a BHN of 10 ( Common jacketed bullet cores ) performed
well with both 7.2gr Alliant Unique, and 5.2gr Hodgdon's TITEGroup, CCI #300 caps, Star-Line Brass, and crimped to an OAL
of 1.570".
I was disappointed to find that the RCBS bullet would regularly hang up on the chamber mouth while shooting my Uberti Henry;
I like the broad flat point of the #44-200CM, and hope to get to the root of this problem...
