Schmidt Rubin 1889 reloading

Hey Guy's, i purchased a Schmidt Rubin 1889 7.5x54.5 swiss a few days ago. serial number is 206XXX so it dates 1896. I need Help for reloading. i only have 50 rounds of original 7.5X54.5 that came with the gun and are not reloadable because they are berdan primed. it's possible but to much trouble lol

i will use 243 winchester brass trimmed to 54.5mm . What kind of powder and what amount i should put in the brass to reload them. they need them to be at around 1800 FPS

Thanks

i found some 7.5x55 brass . same question, what powder and how much should i put to be safe ?

Try posting in the Reloading for Milsurps forum...:)

I'm using 35grs. H4895 with 178gr Hornady Amax bullets, and Winchester LR primers and leave the brass as is for the 7.5x55
Which club are you shooting with?
