Schmidt-Rubin 1889 Ammo

[EddieCoyle]

I picked up a beautiful sporterized Schmidt-Rubin Model 1889 over the weekend.

I read that these can't shoot the GP11 ammo because they're not designed to withstand the pressure from that round.

I've also read that some were rechambered for .30-30 (mine isn't), and I've also seen websites where the 1889's chambering is called out as 7.5x53 as opposed to 7.5x55.

I have a couple of questions:

WTF is the chambering for this rifle?

If it is chambered for the 7.5x55, would it be safe to shoot some rounds loaded using .30-30 data?

I thought it was 7.5 X 53.5 mm .

do you have brass for it?

Nope

GP90 ammo... someone posted a few weeks back that they make their own.


Edit: USMA-82 does it... might check with him on what he uses.
