All im saying is the S&B 7.62x39 SP ammo is its cheap and tests ive seen show it performs as designed. Ballistics are pretty close to a 30-30Win and its reloadable brass with the correct .311 bullets. Thudy Thudy has killed a mountain of deer. If is was going to use a premium bullet it would probably be the Federal Fusion SP ammo. I think MidwayUSA had it on sale cheaper than even Rem or Win ammo. Reviews with chrono reading show its also some good stuff and it also uses the .311 bullets. ATK owns both Speer and Federal. Im pretty certain they are using the similar Hot-Cor and DeepCurl method of bullet construction.

I probably would not waste my $$ on stuff loaded with bullets like Barnes. Its super expensive and i dont see the performance gain IF ANY to be worth the extra cost. Maybe with another caliber but not in this situation. Its rather a shame you could not get the CZ 527 in the 6.5 Grendel. Its not that im a huge fan of the Grendel but i really like 6.5s and mini actions. The 2 would pair up very well and im sure you would love it for deer hunting.
