I have a supply of Buffalo Arms Hornady 220 Swift converted to 7.62x45. They work fine, but are like $2 each. Just for the hell of it I got some PPU 7.62x39 blanks to try and convert them to 7.62x45.
1st attempt - clipped off end of live blank with snips. Dumped powder, opened up end of blank with tapered punch and hammer to fit into decapping die. Decapped, annealed, and resized in 7.62x45 dies. Fail Case split.
2nd attempt - Fired blank in AK, grind fired case to approx length on belt sander, anneal, lube with Rooster's Red, and resized in 7.62x45 dies. Result had shoulder in the wrong place. Loaded it anyway, (wavy case mouth and all) 26g of IMR4198 and Hornady 123 SST, salvaged primer from another blank. Fire formed almost perfectly. Hit 100yd gong. Lubed, resized, trimmed and loaded again with Win LR Primer, same bullet and powder. Hit 100yd gong, again. Repeated this for a total of five firings. All five hit the 100yd gong. Case looks great. Should be good for several more loads. 286975
