jeez, thats heavy for a .22 .. i guess you could stack 3 - 7.9's and fire them over a chrono and just see lol ...
Standard .22 is 14gr. Jsb 18.1gr in .22 cal is called heavy kings. So why would someone want to use a 21gr in .117?whats next. 34gr .177? Lol
Late 30's and I use a 600mm .177 liner, a 700mm .177 liner is being relased later this year, that may help a bit, tried all the larger TP's etc. didn't make any difference.
I expect the M3 will make some pretty good power in .177 for sure, if you have the barrel length to do it. I've gotten my maverick with a non-FX barrel (machined at about 25" or 635mm) over 50 fpe pretty easily. I think it topped out a little over 1000 fps with with 24 grain Griffin slugs. I'll also note that was with Huma extra high pressure regs in the gun. I can't speak on the M3 magazines, but the Maverick magazine holds 23 grain .177 slugs easily, but will hold 24 grain with very minor modifications. It holds the 24 grain with no modifications, but they don't always cycle. They are right on the limit of being too long, but some minor dremel or sandpaper work will make them cycle just fine.
My Maverick has been modified for power a bit, but the M3 should be able to get very close in power bone stock.
