I am starting out on a new build and I plan to consider all options. This may have been covered elsewhere and if so - please by all means point the way - I just haven't found it yet after looking. At first I thought to build your basic 7.62x39 mainly because of cost and ballistics, but that was back when I thought there was little difference between it and the 30-30 deer round. Since I have been disabused of that thought now, I am looking for input from those who have a lot more builds than I under their belts as to what the: 1. stumbling blocks would be in barrels, mags or ramps 2. reasons for dropping the idea altogether - pressures, ballistics, range etc 3. benefits would be 4. bullets, loads and practical employments would be I don't hunt a lot but I do tend to think of the round as a decent deer hunting round, easily found and useful and so started to think of this as a possible build. Cheap doesn't hurt and useful is always good when it comes to something other than paper punching. And I have no aversion to that either.. Since the mags are not at all the tube of a model '94 a whole range of projectile types are opened up as well as weights and powders so - jump in! And - I don't mind being told it's ridiculous if there is a valid reason to back it up - I'm not, however, trolling for trolls. If you want to tell me to build a 300 Blackout or whatever your favorite AR build platform or most appropriate deer caliber is, great but that's been addressed elsewhere - I'm not looking for that either. I'm just getting old enough to want to experiment a little and I have always loved the 30-30 cartridge and would like to do more with it.
