Bill I'm using 130 Sciroccos over H4831SC. Shooting in the teens or low 2's if I do my job. Will check load data again and get back to youAny experience with 130 grain Scirocco in a 26" barrel? I'm starting load development. Looking to do some long range wolf hunting.
Go with your H1000 load. An ES under 30 is good to go. I'd play with primers and see if it makes a difference. BR2's and 210M's are always good. Always try for single digit ES, but sometimes you just can't get it.
I'm loading for my new 28" Krieger barrel. Thought I was done, and wanted to rezero at 200 yards and see how it grouped at 300. Well, I must of hit the break in spot of around 100 rounds down the barrel, because everything was now over pressure. I pulled out my Magnetto Speed and found the 4 different loads were running 60-80 fps faster than before.
Luckily 3 of the 4 were pretty quick to fix. Plugged in the new velocities into QuickLoad and had a pretty good idea what to drop the charges to. The only one that was still having issues was my Retumbo/Lapua brass/140 gr VLD. I switched to RL 23 and problem was solved. I have an ES of 4. Now I've got to tweak the seating depth to dial it in and snug up the group.
H4831, RL 23&26, and Retumbo have been the main powders I've used in my Norma. I torched my last barrel because I loved shooting it too much.
Below is a photo of the load using the 124 gr Hammer Hunter and RL23.
Man, that's deep. Now I'm really thinking. Lol.You can experiment forever. Gotta love Cal Zant's analytical articles on this and other subjects. Very interesting and often surprising statistically driven conclusions. Note that going from 10 to 3fps in SD only increases probability of a hit at 1000 yards by 1.4%!
