The 1/19 does make it tough working up a load if you try to use the long radius ogive. I resigned myself to use the original profile bullet in the .44-77 and the .44-2-5/8bn. I beat my head against the wall for several years trying to make a sleek nosed bullet shoot at long ranges with the 1/19 ROT. They make a good showing out to the ram line but fall flat on their nose past 700 yds. even in the faster 2-5/8 bn. The 2-5/8 bn shot quite well at the MT 1000 during the days before the match with the few Brooks GG postel's I had left over from the Q. I ended up using the KAL Elliptical to shoot that match and they done OK but far from the postell nosed GG.
The .44-77 I shot a lot at the Whittington center using the original profiled bullets and they put everything down out to the Rams and stayed on that buff up on the hill side using the .485 gr original PP bullets using the Lawrence rear and front blade barrel sights. But I have to say the flags where hanging limp that morning.
One cant feed the rifle something it's telling you it don't like
