So the magazine in my maverick did not like getting fed with 20 grain slugs, and the rifle more or less jammed with every attempt to chamber a shot.
So what is a man to do ? hit the internet shops of course and spend more money.
So i ordered a Carm slug magazine for the maverick, and a single shot tray for it too, and then for kicks a magazine for my Vulcan 3.
And i must say so far it have all worked well, i put a heavier hammer in the Maverick as the stock one did not allow for much more than 800 FPS speeds with the 20 grain slugs from Zan, and then i cranked up the REG pressure a little.
And now i have to go to power wheel setting #1 and loosen the hammer adjuster to the max if i want to shoot 13 grains and do that at reasonable already confirmed good speeds.
With a bit of hammer adjustment and on PW setting #7 and the 20 grain slugs fly 970 FPS.
So now i am good to test those at reasonable speeds next weekend.
I did not specify any particular colours when i ordered at Carm, but i got black and toxic green, which i think work fine.
I have not tried the AGT magazine other than it fit in the rifle, but i think i might end up liking it more than the original AGT magazines.
