Michael C. Smith · Feb 21, 2019

Could someone please run a quick load for me.
243
24in. Barrel
Fed 210 primer
95 nbt
H4350
Imr 4064
I am using federal brass I dont have a water capacity.

I have been trying r19 and getting very erratic results. Think I need to switch powders.

Thank you Michael

Thank you @DrMike so yesterday I shot a ladder with r19 from 42 to 44.2 grains moving up in .2 grain increments. The first 4 shots 42 42.2 42.4 42.6 hit in a spot that you could cover with a quarter. Shot 5 moved up 3 inches. Shot 6 came back down with the first 4. Shot 7 8 and 9 were kind of scattered. Shot 10 through 12 landed pretty much on the same plane as the first 4 but they were scattered horizontally over about 3 inches. So I loaded 6 rounds of 42.2 grains which was in the middle of what I thought was my nose in this is what I got. Which really doesn't make much sense to me. Conditions were good wind was calm. This was the reason for the quick load with the different powder. Thought I would try something else this r19 doesn't look like a good combo. Thoughts ideas?

Thank you Michael

Yeah, try H4350! IMR7828 SSC is a good one as well.

Try vit n160

Going to shoot a few loads with h4350 today. Yes I want to try n160. What do yall think caused those shots to go so wild.

I have certainly had good success using VhitaVuori powders. N160 has worked well for me in several standard cartridges.

Ladder testing is usually done at an extended range. 300-400yds. At that distance, you don't worry about the horizontal spread, but at 100yds that's telling you that it's just not a very good load combo for your gun.

Yep that's what I am thinking to.
