Anyone loading the .338 Norma? What are you using? What bullet do you like most?
This cartridge was built around the 300SMK. along with SAAMI reamer. The cartridge doesnt respond well to the usual powders Ramshot magnum will give the best velocity with R-22 second. Both powders were used extensively during testing.
The following powders shot bug holes, but only Ramshot and 22 reached the FPS I wanted. H-1000 was a little light on FPS but extremely accurate.
Ramshot
R-22
R-25
Retumbo
H-1000
Near top under- LRH AND SHOOTING, THREAD- more berger 300 hybrid gen. II TESTING, Shawn C. tests. Pict is pg. 2 or 3Where you find that picture?
What powder charges were you using and what velocity?
What did you use for H1000 and primer? What is your barrel length.
