What cartridge is this

[zg47]

I just picked up a Ruger#1 that has had a bit of work done to it.Rebarreled ect.The problem I'm having is there is no markings on the barrel and the owner is deceased.I got a bag of brass which is stamped 375H&H but by looking at it I know it aint.Shoulder angle is way to sharp.So my question is can you guys save me a trip to the smith???Is it a A.I version or a 375 Weatherby?Thanks Hope these pics help

I'll guess Weatherby ..

not sure, but weatherbys have very rounded shoulders, whereas a ai has shrp shoulders.

Some measurements would help, it looks like either a 375 A-Square, or possibly a 375 improved

 

[zg47]

case length is 2.825
measurment to bottom of shoulder is 2.422
measurment to top of shoulder is 2.500
Thanks guys

Did you mic the bullet diameter? Just because the brass reads 375 does not mean it is. (358STA maybe???)

I enchanced the photo and that cartridge is definitely a 358 STA wildcat

I enchanced (enhanced?) the photo as well and now have a few dozen phone numbers to sell to telemarketers!

Is that a first?

Get a gunsmith to make a chamber cast and tell you what you should shoot in it...

It looks closest to this one..Scroll down to 375 improved and view the specs. The 375-A square is shorter at the shoulder, measuring only 2.175

Looks likethe bullet is a wild cat by Ackerly Improved(not sure of the spelling) but basically the shoulders are blowen out to accommodate more powder. They did it to the 30-30,30-06 as well as some older calibers. Shoot the same cartridge as the head stamp,as you have and they will form fire out to have sharp shoulders. You could get a set of dies from RCBC if you send them out of the cases.
Hope this helps.

The shoulder angle looks very similar to some I had a couple of years back that were made from 375 H&H; they were called 35 Mashburn Improved and used same loading info as 350 Alaska Shooting Times or whatever its called.
