I figured I would update you guys that are pushing your Mavericks pretty hard with the heavier slugs. If you want to get the most weight that will fit, I believe the Griffin 36 grain flat base slugs are going to be the limit in .22(without magazine modifications). I ordered some hoping that they would fit, and they do! They cycle fine and no hang ups. They also seat just fine, with no issues pushing them home. By the looks of it, that is going to be the limit. There isn't much room left that I can see.
I measured them at .4225 inches long. The magazine might hold a .425 inch long slug, but I don't know for sure. I think that will be pushing the envelope. I hope to get some on target with in the next week or so to see how they do. My superior heavy barrel seems to prefer .218, and that's what these are. I did some chrony testing tonight to get the gun setup for some target testing. The big question is going to come down to harmonics I think. At full tilt, the gun was slinging them at 1032 fps! If I back it down to 1000-1015 fps, the gun is much quieter and smoother. I suspect the 1000 fps range is going to be the happy place for them, since that's a little below the max speed and a little less "violent" of a shot cycle. I will update as soon as I get some on target.
I previously did some testing with some VK 34 grain and some Griffin 34 grain slugs. Both slugs showed promise, but I think I was having some harmonics issues that were temperature dependent. In the heat of the day, they were shooting lights out from the superior heavy at 1000-ish fps, but the next morning the groups opened up. I tried speeding them up and slowing them down that morning, and they refused to group as well as they did the previous afternoon. I believe they would have done better with a little higher reg setting and tuning below the knee a bit. Since then, I carbon lined my liner, so I know that will change things too. Hopefully, it won't change my accuracy for the worse... I will try and give those a test when I test the 36 grainers.
P.S.
On another note I think the .30 magazines could easily handle some 70 grain flat base slugs. I don't really intend to test that theory, but thought some of you may want to know. For me, the NSA 65.5 grain slugs are all the weight I need, and the gun ain't gonna have the juice to send them too fast anyway. I think mine topped out around 968 fps with those, and that's pushing the gun hard(Huma extra high pressure regs). Yep, that's 136 fpe! While it is cool to see what the limit is, I don't think I'll ever actually tune the gun for that power level. Maybe 130-ish fpe, but that's about it. I don't see a reason to push it that hard, because 130 fpe will do anything 136 fpe will do, and is less likely to break the gun
Anywho, I just wanted to share what I've learned in the Maverick magazine front, so you guys won't be wondering what will fit the magazines. I'll update when I get rounds on a target!
