Just a contentious point on 30-30 vs 7.63x39.
While partisans of the Soviet round like to suggest that they are the effectively the same, let us point out that they are not. First, while things have improved, there is not a plethora of proven hunting ammunition in 7.62x39, whereas Walmart available Core-lokts are very good in 30-30. Secondly, I am unaware of any 170 grs bullet weight available in 7.62x39. Thirdly, either loaded Leverevolution ammo or hand loads from the same components offer 160 grs at 2350 from a 20” barrel, ballistics that cannot be matched by 7.62x39. The CZ527 platform (or Zastava mini-Mauser) are compact, handy platforms and those attributes may offset the relatively minor shortfall in ballistics by the 7.62x39. But there are differences between the two cartridges that bear remembering.
