Just wondering what you guys have seen from your superior slug barrels, especially in .25. I haven’t gotten satisfactory accuracy from slugs yet out of my dreamline. Ive looked for anything really on it, and came back petty much empty handed.
Results on the superior slug liner?

Perhaps when they are actually available for purchase more members will report on their experience with them. As of lately they have not been available in the USA.

It seems that utah airguns have them in .22, but everything in .25 and .30 is out of stock. Thanks for the info though.

I've had a Superior Heavy Slug liner for my Impact MkII 600mm in .22 for about a month. Have had great results especially with NSA slugs in 31.2 gr. at 850 ft/sec (100 yrds)

@bobgm3 - impressive groups. What reg pressure are you shooting at? Did you do much harmonic tuning?

In 25 cal the heavy Sup slug liner did not shoot as well as my original slug A or superior standard liner, ( these are basically the same) but I only really tested a lot with lighter slugs, nothing over 38 Grn, and I didn’t go over 990 FPS, so results may vary? Those are mine

I have tried both superiors in .22 and .25.
And to my surprise the superior standard out perform the superior heavy in slugs and pellets. Both liners are very good and easy to tune with almost any pellet or slug but the standard has a slight advantage in accuracy in my experience.

i have been having great results using a standard superior liner .25cal out of my M3 with 36,38g prohunter slugs and 39g wildman slugs, i am yet to use a superior heavy liner as the slugs and king heavy mk2s have been grouping sub moa at 100 yards ,so its a case of "if it aint broke dont try and fix it"

I have had great results with the new Superior Heavy in .25, 600 mm Crown, especially with 34 gr Mk II pellets.I have excellent results with the JSB KO 34 gr slugs as well, but slugs are too expensive to use as a regular diet.
