Apples to apples - the envelope is the same regardless of the generation of LR PMags...
You have MagLULA experience that I do not, thus I am inclined to believe your assumption is correct. It fits too with Guy's ignoring my comment about G2 vs G3--otherwise I might've expected to hear some sort of caveats from him i.e. "we're waiting on Gen3 samples to confirm fit" or some such. But he didn't qualify availability in any way; if it were me I'd have included some sort of hedge, if not on fit then of ETA, just on general principles!
Apparently this thread is confirming my premise, that no loader exists on Planet Earth that works with 308 PMAGs; I'm really surprised about this!
