hello;
first let me say "thanks" for the input by others. never can leave things alone. back to range today. rifle is a howa mountain rifle with a 20" bbl.
spent some time looking for more reloading data on the .243 win. with 95gr. nosler bt and 100gr. rem. bullets.
100gr. rem. bullet, worked up to 44gr. of imr 4831, speed 2940fps., no sign of pressure, easy bolt lift, primers are not flat, group size .685". found something!
95gr. nosler, any thing above 42.5gr. imr 4831 got big changes in speed. avg. 2800fps, but min and max speeds were 100+fps difference.
4 shots, even with a little time between shots, and the bbl. got HOT HOTT
HOTTT!
thanks again for info.
