M1889 Swiss Schmidt-Rubin

Bit the bullet and picked this one up to expand the Swiss accumulation. Mfg. 1893. Mag is a mis-match, but looks like the replacement was done some time ago. P30 mark on left receiver. Am I correct in that this indicates it passed out of service to an ex-serviceman, possibly in 1930?
Didn't hurt at all that as an antique, it was shipped right to my door with no interference or interaction whatsoever from/with various restrictive governmental entities. A pleasant whiff of times past there.
I'll be slugging the bore when I get a chance in order to produce loads appropriate to it's design. Attachment 133943Attachment 133944

Please keep us updated on the load development. I got one of these last year, but am still too busy shooting the others to really have a chance to play with this one yet. But I know I will want to!

May take a while until testing. My shooting spot for years was closed down by conniving local authorities. Option B involves a minimum of an hour and a half drive each way. It'll happen though. There are some older threads here on the subject. I'm intending to start with two angles, a 220g RNFMJ , and a lighter cast bullet load.
