FX I finally found the slug for .25 Superior 1:24

I've been trying to find a slug since April that performs great out of my .25 Dreamline's standard superior liner. By great I mean performs nearly as well as 25.4fx pellets in terms of accuracy... tried a QUITE A FEW. Nothing performed anywhere near as well as pellets, not well enough to give up the near perfect grouping capability of this gun with the 25.4 pellets. Why sacrifice MOA performance out to 100, 120 on a good day for some extra energy and range... Most shots aren't made at 120+... Best I got was H&N30... But at low velocity, pushing the 30gr past 900 from a dreamline sacrificed a lot of air. This weekend I got a bug up my butt and wanted to try one more slug. Hybrids were just OK, NSA didn't agree with my barrell, the original ZAN formulation was one of the worst performers, knockouts at 34gr was just too heavy. Then I saw zan changed the slug recently. (Recent to me). I bought a single pack of 28gr .250. holy crap. At 917.6 average. Hole on hole. This is at 50 and I'm holding groups no more than 10-15% wider than the AEA 25.3s I'm currently using as my new preferred projectile. I've seen the question asked before.. give the new ZAN slugs a try. Specifically 28gr .250. 915/920 is a good starting point. I tried them at 860,880,900 and 915... Every single increase tightened the pattern. I'm going to tinker a tiny bit more with pressure and velo. But actually excited. 40 ft lbs at 100y compared to 22fpe is huge.. still going damn near 800 at 100y

Glad you were able to find something that finally works! Btw Varmint Knockers makes more thsn just the 34gr, he has some new 30gr slug that works very well. Also has the 32.8gr, there are heavier but you're looking for lighter ones.
 
I've got a p15 that I put a 23" LW unchoked barrel on, that shoots the 28gr Zans like a laser at 890fps. That's about the most I can get out of the gun for power too, around 50fpe, it's enough. If it weren't for these slugs I would only be shooting pellets, none of the others I tried even came close to being accurate enough either.
 
Congratulations! Also try cleaning your barrel, it just might tighten up the groups a tad more.
I shot about 75 experimenting with velocity and then I posted the original post... Then filled my tanks went outside and it shot way worse..

Then I figured hmm.. "maybe my barrel is just extremely leaded, it's been about 5 tins of 300 and now 200 or so slugs after the first session," so I took my barrel off, cleaned inside the shroud, the discs and orings that keep the liner centered in the shroud, greased the rings, ran a bunch of microfiber cleaning latches soaked in ballistol until they came out clean, cleaned the moderator. Was pitch black out by the time I finished, so after work today I am going to test it again. Hopefully that brings it back to the performance it did yesterday afternoon. I was able to shoot in my basement tuning lane but that's only 14y, but it did give single hole and 1 and a quarter pellet width clover leaf groups of which I tried 4... One 16rd mag. I hope the clean barrel does it. What I saw yesterday really excited me. If not Ill just go back to AEA which does 1moa or less. But that extra distance and retaining 40fpe at 100 is huge.

Look at the comparison.

^This! Some barrels, and some slugs, need you to clean the barrel a lot. Still worth it though, if you find one that works.


The results are in. It was leading. 35y .3"ctc 10 shot groups. I'm fine with that. That's .6" at 70 in theoretically 1.2" at 140. Although that's what I expect and would be very happy with at 100. So. I am thrilled.. the best aspect is I don't have to adjust the internal hammer spring screw or pressure. Same exact settings on the reg and internal HS screw was my AEA pellet tune, just 5 notches up on the power wheel. Smaller SD and extreme than the pellets, which was already good. So I'm thrilled. Already two tree rats down. Quite literally doing my confirmation session both WHILE IM SHOOTING. Get onto my bird feeders. Adios Bucky

Cool! Glad it worked! And great shooting especially on the 2 tree rats!
 
You need to track your accuracy to find out when you need to pull a patch through to keep your accuracy up. You don't need to clean the shroud or suppressor that often, if at all, actually. I know it makes some people feel better, but try not doing it and you will see my point. Shooting FX Hybrids out of my Paradigm, I have to pull a patch every air refill, about 35 shots. I don't know how many pellets it would take, they seem to always shoot good. Slugs are a totally different animal. If you figure out your number for your barrel you can keep accuracy going for quite a while before you actually have to do more than just pull a patch. This saves a lot of time to do.

I haven't cleaned the inside of the shroud or the moderator in 5 months. About 3200 pellets, and 600 slugs. The jam nut and thimble looked like a lead blizzard. The spacer discs were worse.. I had the shroud off. So I did it. I've shot 2 full mags so far.. it's tightened up some since being leaded. I would imagine a LW or CZ barrel takes on more lead than STX. Either way. I'm shooting single hole now at 35. Gave a tiny bit more pressure and spring and now the 28s are flying like lasers at 938~941fps. I'm thrilled. I am at the point where I'm not using the actual 1" EBR Target 10 Ring. But individual pellet holes as targets... I'm so content with this. No slug has come close. I already keep a log book. Also have a little bit of a terrible case of OCD. My bench has stacks of tins. (DATED on day of last shot... The stacks are separated by baggies of fouled patches from cleanings.


Edit: in my mind I just look at the 35 group and multiply by 3 for estimated 100y performance. This weekend will be the true test.
