| Okay, I finally got to test one of these out. We had a real nice
day here yesterday, so I sneaked out to the range around 5:00.
I had 5 rounds of .300 WM loaded.
Bullet: 180 Sierra SPBT
Powder: 80.0 gr. H4831
Comments: Ouch!!!
Each round was more excruciating than the first. I am working up
to somewhere between 81-84 grains of H4831. The group I got yesterday
was pretty good. They were all within a 3" circle and the last
4 were all over each other. (1 stray out of 5)
I am hoping to get a tight group with the Sierra SPBT and then I
am going to switch over to Nosler Partitioned 180 grain bullets
for a hunting load. I hope I don't have to shoot too many rounds
to perfect the load.
Brett.
