STX vs STX heavy

.22 wildcat mk3 BT comes with superior standard. .

Can that handle and stabilize 21-25gr slugs fine as is? All the ads I see say "for heavy slugs" on the "heavy" liner. Is all that is different the twist? Or is it left unchoked?

One thought I can't get out of my head. Every single Lothar Walther or CZ Barrel is 1 :17.7 give or take. How can 1:24 which doesn't bite into the projectile as much sufficiently stabilize traditional slugs?
 
It aint. You need the heavy for long mid to heavy slugs for you caliber. The heavy barrels have a higher twist rate. The standards are for pellets which are self stablizing and they can shoot shorter slugs as well. When they get longer the slugs need faster

STX superior 1:24 doesn't even do that great with lighter slugs. I fail to believe even a 28gr slug out of a 1:24 will fly as well and true as it would out of a 1:16-1:17.7 .

Superior pellet is FANTASTIC with pellets. Absolutely poop the bed perfect.

With ONE SLUG. I have found decent results. And it ain't hybrids.

I have seen the exact same gun as mine with a STX Superior heavy (now labeled slug) liner pull 1moa at 100 at the same velocity. Is this the typical result?


I can get hole in hole results at 50 with pellets at 899 fps tune I'm currently using.

I have a 500cc 250bar fill getting me 100+ shots down to 150bar with 25.3s at 899.. my SD is down to 3fps and my extreme is 9.

I give the PW 2 clicks up to 15 and I'm doing the same speed with Baracuda Hunters or 921-930 with hybrids. Over 1" groups. H&N30 at 860 .7-1.2 at 50, hn28 same, zan 26... 2"+ , NSA 26.5 1.5". Now zan 28 at 940-946 fps will do 5"groups. But that gets my shot count in the neighborhood of 50-55 shots as I have to raise the pressure and roll the wheel to 21. And give a tiny bit more juice to the internal screw to get the spread more consistent.

From what I saw with the same exact make, caliber and barrel length, do with those hybrids has me wanting to think maybe it's not just for only heavy slugs.

Either I'm gonna go the cheaper route and just get a slug liner... And stick with .25. Or get the 22 caliber change kit, get a .22 superior slug liner and have a gun capable of launching respectable weight 22 slugs at proepr slug velocities. I know my dl tac can do over 980 with 23-25gr slugs.
 
Yea a 28 grain .22 is a long a** projectile for stx srd.. I dont have any .22's i only shoot .25 and .30's and 90% of the times it's. 25. The .25 26grain slugs shoot fine. I like 25 grain pellets. It can kill anything a 26 grain slug can kill. Its cheaper and pellets are nowhere near as dangerous to shoot as slugs after they pass through the animal. I look at it like this, for me anyway. If I'm 100 yards or less i can 100% take out a coyote or smaller game with a pellet in the vitals and they will either drop immediately or not make it past 25 yards with a .25 and most of the time it pass clean through.
I like pellets 😀

My gun is a .25. 28 is not large
