Swift Manual - 270g - 375 Ruger - Varget - RL-15

[darkwing327]

Hi,

Need load data from possibly a newer Swift manual that shows the 375 Ruger with the 270 A-frame using Varget and RL-15. Mine shows the H&H and I realize the Ruger 'should' be about 3 grains higher, but if someone happens to have a manual with this load data, thought I would start there.

Thanks for the help.
Darren

Thank you very much sir. Tells me exactly what I thought to be true. The 74.5 Varget max is 3.0 grains above the H&H at 71.5. But always nice to confirm. AND it saves me cooking off a number of pricey bullets just looking for pressure

Interestingly, I was expecting a higher pressure and velocity as the H&H is showing 2721 fps at max load. Not that I need the speed as this is a <150 yard round, but interesting. Will have to see what the chrony says.

Thanks again.
