try both, results may vary
After several range sessions the usual rule that each rifle is a law unto itself proves true again. Chinese 7.62x54R match accuracy in my 43 TULA PU, not so hot in several of my other Mosins. Circle 10 71 ( Bulgarian I think) only average in my PU (3" groups at 100meters), fantastic in my M38 better than groups with scoped pu on a snowy, ground fog day. Chinese good groups with my SVT , BUT occasional FTF. The rounds would fire with second strike. Circle 10 in my SVT ran smooth as butter and better accuracy. Never had a split neck in 500rds of Chinese , had a split neck with Circle 10 ammo in my PU yesterday. Have some Czech ammo, silver tip in 20 rd green boxes, shoots poorly ( bad groups) in everything I tried it in, Cases look like they have a lacquered coating so given that and poor accuracy record I haven't bothered trying it in m SVT.They don't chamber easily (sometimes not at all) in my PU.
