Well Roger now I have to dig out my book.
I did a 49-2x back on May 17, 2003 during a practice session. The target was the standard NMLRA single bull 100 yard x-stick match target. Haven't
seen a score like that in years since, though I manage now more in the range of 45's to 47's, give or take a point or two now and again.
The rifle was my 1" x 37" - .50 caliber Douglas barrel with the 57sml Lyman peep along with the 17 aml front globe sight.
Load; 75g 2fg Goex - .495 Hornady Ball - .018 Ticking Patch w/TC 1000+ Lube along with a newspaper thin paper patch between the patch and ball, #11 RWS Cap.

Just as a side note I once did a double '50' at our club shoot from 50 yards using the NMLRA double bull x-stick buffalo target - 5 shots each bull;

The rifle used here for this was my; 1 1/8" x 36" - .50 caliber GMB with adjustable rear sight and shader along with a "pin" front globe sight.
