All USGI 15 rounders, some new in wrap == but I have just ordered a bag of Wolff springs to make sure they aren't the weak link.
I will also try some Speer SP and some Hornady JSP, maybe some Winchester, too - various folks I have read said these brands were
feeding OK - of course, some said the same about the PrviPartisan SP's...
Thanks for the feedback - I will advise when I've had a chance to try the "variety pack" of ammo...
