I'm wondering how the .338 250gr would do at moderate velocity? Say 2500-ishI'm contemplating a .338 RCM build on a Tikka, so it could be seated out plenty long.
The seating issue was the Achille’s heal on the 155 in the 308. It would have been NO issue in a 30-06. The boat tail encroached the powder space to the extent of compressed charges. I could have used a flat based bullet to solve the problem but I just can’t deny my liking for the Scenar & short actions overall.
When I'm loading I like a powder that fills close to the junction of the base of the neck. Then I like bullet's seated to the base of the neck at most. I don't like the bullet encroaching on the powder space at all.
My best load was 48.5 gr Varget which filled the case to the top. Not much room left to seat the bullet. So, I had to find an alternative. Fortunately, TAC saved the day with no loss of velocity.
I'm glad your loads worked out also.
By the way, in case you missed it, Jeremiah was a bullfrog.
