What pellets shoot accurately using a Marmot Militia Barrel?

[X27]

I have a .22 cal Marmot Militia Barrel in my marauder pistol, I know lubed JSB 18.3 grain shoot like a laser. 

I have tried to shot predator polymags both regular and short but it feels like you have to grind them in the barrel and that don't shoot accurately.

It is like this with most pellets.

What pellets have you tried with success with this barrel?

I am really interested in a pellet or bullet designed for hunting with good terminal ballistics like a hallow point.

I have shot the CPHP out of my woods walker/MM in .22 and had decent groupings at 30 yards, the longest I have bothered to print paper with that gun. The longest kill shot that we have recorded is 62 yards on a jackrabbit. The barrel did like to be wetted when brand new, now 1000 pellets later it does not seem to matter much. Just a drop of pel gun oil in the skirt would lube the next 20-30 shots, then as the barrel dried out, the shots would wander low and to the right a bit from POA. Another wetted pellet and the gun would shine again for 20-30 shots.



Shoot'em good

I had some good grouping at 35yds with h&n but I can’t remember the grain or head size. I shoot the jsb 18 grain out of mine now though because I have a bunch of them. I’ll have to try and figure out what the exact h&n I shot and let you know.
