.30 FX Impact 700mm DonnyFL Ronin, regulator set to 141 bar using an EDgun EDMU, power wheel at max and no slack, valve stop line 4. Range is 55yd, wind light and variable blowing towards me.

890 fps for the 47g Nielsen hp

910 fps for the 45g JSB pellet

G1 is 10 shots with the Nielsen. 1st shot is low right, the next 7 clustered tight 2 inches above it, then two fliers above and left.

G2 is 7 shots with the Nielsen same settings.

G3 is 5 shots with the Nielsen same settings.

G4 is 5 shots with the JSB pellet same settings.

G5 is 5 shots with the JSB power wheel at 5. Each step down on the power wheel lost 11 to 13 fps.

G6 is 5 shots with the JSB power wheel at 4.

G7 is 5 shots with the JSB power wheel at 3.

G8 is 5 shots with the JSB power wheel at 3.

G9 is 5 shots with the JSB power wheel back to max. Only the max setting made that resonating PING sound with each shot.
 
Matt Dubber told me not to shoot slugs in a ST-X pellet liner due to it being choked. He said to wait for the Slug-X liners, so I'll wait.

If you had pellets that grouped like those slugs did, would you keep using them? Please don't take offense but those slug groups are proof to me that Matt was right when he said to wait for the proper barrel liner for them.

I have a bunch of .22 NSA slugs that I wanted to use in my S410 TDR, but they didn't group well even in the LW barrel.

Hopefully I'll get to try them in another gun as I would like to have better performance for long range and windy conditions.
