How did it work for you? That one has satisfied me for decades. H&G 68 or commercial
clone and 4.8 TG.
I THINK I get slightly more accurate results with 4.2 TG and 452460, but the difference
is small enough to be not totally convinced. Seems true with one or two guns, but
not by a lot. Rem brass has definitely given me better results. No clue why, but
it is repeatable for me, compared to Win, Fed, and Starline.
Alliant online reloading guide says 4.5gr Red Dot is max for 200 Speer LSWC.
Says 831 fps from a 5" bbl.
Hodgdon online data says 5.4gr TG is max with 200 LSWC, says 877 fps from 4.8 gr
and 957 fps from 5.4gr. I haven't chronoed it in a long time, but 875-900 is what
I remember getting, so that fits with Hodgdon pretty well.
Back when Major Caliber was 180,000, I loaded 5.0 gr for ~925 fps average. After USPSA
dropped it to 170,000, I went to 4.8 gr which was probably actually 175-180K, so safe
for 170K limit. Now it is 165K, to satisfy the .40 S&W folks. 180 gr at 917fps makes it,
or 165 gr at 1,000 fps. I stayed at 4.8 TG/200 LSWC (H&G 68 commercial cast about
80% of the time).
