Disco grouping ? good or not?

[shadowr1]

I shot these @ 65 yards with JSB heavies, slight wind.
I was aiming at the top target, I have it sighted at 30 yards.
The top group is with the velocity adjuster turned in, and bottom group is with it turned out.
Both groups are about 1 1/2in.
What is good groups at this range, I'm just wondering if this is good, average etc. I know it's not bad, but I've had accuracy issues and am trying to get them all worked out.
The other holes are 9mm. the right side is sighting in my hand gun at 10 yards, the left is a little better.

Give it some time to season the barrel

Also unless you have the heavy hammer spring try the 15.9gr jsb's... id expect 1in groups or less at 50yrds if the disco loves the pellet ur using...

I've shot about 2k through it. It hasn't got any better. I've got a new barrel coming, I'll see if it's a bad barrel because it's gone to mac1 and still has not gotten any better.

I think that disco can do better. At 110 meters (120 yd) I can make group of 80 mm with Crosman premier ultra magnum

it can do much better.
these were shot today, with JSB exact RS 13.43 grain pellets, at 36 yards (my gf Maya) and 57 yards (me); 9mm and 14mm CTC. Front bag rest.

Thanks, my gun not worthy! I've got a new barrel coming. I should have received it a month ago, but when the box arrived there was a nice round hole punched in the end of the box ware the barrel punched out. I didn't notice the hole until after I opened the box and to my surprise, I was the proud owner of a MT box. Crosmen was very helpful and another barrel is on it's way.

I doubt it is a barrel problem, the Disco barrels are fine. You should keep trying to find its favorite pellet..My 50 yard groups with 14.3cphp are all around half inch to inch....shooting @900fps

I would try a smaller aiming point, and keep shooting at the same spot for 3-5 shots and that is your group.

good luck



P.s. I will be shooting some 50 yard groups today, so I will post the pictures later.

That's alright grouping; you might want to try some different pellets. Mine loves CPHPs and CPUMs. On a good day I'm shooting under an inch at 50yds. and right outside an inch at 70yds.

Just throwing it out there ... A touch up on barrels muzzle ( Crowning ) can do wonders on many mass production type gun barrels.

I use a fine "Cratex" point in a dremel tool applying a nice polish to exit area of bore when doing so.

The crown has got to be bad.  Than looks like a shotgun spread

That is unreal good from 57 yards. What have you got done to the gun? My Marauder wouldn't even come close to that at ~60 yards. My 50 yard groups look more like your 100 meter groups.

Great job though
