So a friend mentioned he was building a golf ball launcher for his HK51 and I have 2000 rounds of 7.62x54R blanks that just showed up today. Another friend has 7 or 8 mosins that he will sell me for $45 or $50 a piece...I can't imagine it being to hard to thread the barrel weld some pipe onto a muzzle brake... I have 24 boxes with 96ish rounds in each of this shit. It's going to last me forever. Any ideas what would make this project easier?
