I just sold a LH SS A-bolt in .375 yesterday...
I do not recommend it.
Aside from the "usual" reasons not to get an A-bolt, the .375 has a few additional strikes against it:
-26" bbl (I shortened mine to 24")
- it is very, very light for caliber
-plastic stock is quite "squirmy" and inconsistant (I put on a take-off medallion with cross-bolts >> then a Laminate)
-loading port is barely long enough to eject a case - and much shorter than what it takes to get a loaded cartridge into the magazine box. you have to kind of angle a round in, fish it back with your finger, then depress it into the magazine
-both of the .375 A-bolts I've shot have had mis-fire issues, largely due to the safety design
you'd be better served getting almost any magnum bolt face action and rebarrelling.
