Today I fired my M39/SOV replica in preparation for upcoming Camp Perry Natnl Vintage Sniper match. At 100yds.
Mild load: PPU brass, SMK174/.311, WLR-M, 49gns H4350, light Lee factory crimp, ~2400 fps. The match is shot at 300 and 600yds.
I have shot this same rifle/bullet at 1000yds with 53gns of H4350, ~2780 fps.

10 shots for score. Need higher X count!

Wow, you have nice combination. Btw cleaning rod missing ;)
Normal I used Sako and Lapua brass, but my daugter use S&B cases. She get very good results, reload N120 and light bullets to normal 150m distance.

Thank You!
I developed this load specifically for a 1000yds match. I was struggling with getting consistent velocity. SD was 30-40fps. I compared to new PPU 182gn ammo. It had SD in the 8-12fps range.
I examined the PPU 182 and found that:
- It had a case full of very slow powder.
- It had a very hot primer.
- It had a very strong crimp.
So I got some slow H4350, went to WLR-M (from weak CCI-200) and started applying a light Lee crimp. This brought the SD down to under 10fps.
The M39 has such a deep long throat. I think the CCI-200 was popping the bullet out of the case without consistently igniting the powder.
