What the H am I doing wrong?? Maverick Slugs..

I just ordered four boxes of NSA 33.5 grain slugs to try them on my Sidewinder.

Honestly, Indo not know what to expect from those slugs. Maybe expansion for hunting.

The fact is that the JSB MK II are EXTRAORDINARY accurate on that rifle at from 20 to above 190 yards.

If the slugs are not accurate on the Sidewinder there will not be anything to miss, the 34 grain already gives me what I want.

Try the 34 grain on your Maverick, you might get to the same excellent result too.
 
Hogkiller man- if your velocities are still not up to what everyone says they’re able to get, and it sounds like you’ve gone thru the gun all thru out, the one thing I want you to do is look down the access hole to the screw that is responsible for replacing pellet probes, under your cheek rest. If your transfer ports are 100% in alignment they screw will be closer to the edge of the hole towards the muzzle. If not, that means the cocking bar that’s attached to the cocking rod with the two grub screws has slipped rearward, causing your transfer ports to not line up.

You can realign the ports and if you attempt to cinch down on those grub screws there’s a good chance you’ll round off the allen socket and then now you’re fooked. You can use all the lock tight you want but in time, that rod will slip as one- it’s spring loaded, and two, you’re constantly pulling and pushing that cocking bar every time you cock the gun.

Replace those two grub screws with Torx socket head screws, M4 x 6. I just did thisto a friends wildcat BT for him-

The Torx head will allow you to really conch down tight onto that rod with no fear of stripping or rounding off the heads, and yes, use lock tight with this modification, also

Proper Transfer port alignment-
