Tuning Its official! My edgun r3m .25 shoots slugs more accurately than pellets!

My eddy r3m .25 with hum reg and power plenum.

Reg at 140 hammer spring maxed out and slinging NSA slugs at 950 fps. 

Here are 4 different groups all at 1/2" (perhaps 9/16 on 1. All shot at 60 yards in a moderate breeze 5-10 mph.

Yes 60 yards. At 50, I've had many 3 shot groups that were all touching. around 1/4" ctc. 

I don't have pellets that are this accurate. Although the 34 grain edgun pellets are pretty close. 

The only two downsides to this rig shooting at this speed is the shot count about 25 shots from a 220. Bar fill.

Also the eddy's barrel, while supremely accurate, tends to foul pretty quickly. 

I suspect the aggressive twist rate has something to do with it.

 Here's what the cleaning rag looks like after just 50 shots. 

It's still plenty accurate enough for hunting after 50 shots but groups open up to about double and stabilize there. 

I really am thrilled with this gun. It holds POI like crazy! Honestly ZERO POI shift. 

Very very reliable and consistent. And of course accurate as all get out. 
 
Nice! Have you done any prep work prior like polishing the barrel or have you applied any lube to the slugs? I'm wondering if it would help with the barrel fouling.

Yes. I do lube the pellets with the same clp production use to clean the barrel. But it is not very effective in preventing fouling. 

The only polishing I do is pull through patches. I'm afraid of doing anything more aggressive for fear of damaging the barrel. Any ideas?
