Stx superior liner VS superior heavy liner?

[Gambler]

Ive orderd a superior heavy from huma to replace my superior liner in my .25 crown.
What is the difference in those 2 liners except mayby TR? Ive read several places that the .25 heavy liner can Come in different TR so I Dont know what I get yet. But are there any other stuff to ?

Heavy is intended for heavy projectiles.

Heavy is intended for heavy projectiles.

I think he means what is the actual physical difference between the two......

 

[Gambler]

Heavy is intended for heavy projectiles.

But that is Just because of the twistrate right?

The difference could be both the TR also the choke size and choke length.

FWIW I use normal superior 500mm in my FX Crown for 25gr slugs. Accuracy is perfect.

I ordered a Superior Heavy .25 700mm from The Pellet Shop a week ago and arrived Saturday. Hoping I would get the Heavy 1:18, nope got the STX Slug Liner 1:16. I contacted TPS today and they stated FX changed from the Heavy 1:18 to the Slug 1:16. Was hoping to get the Superior Heavy 1:18 to shoot pellets as well as slugs. I wish they would have sent a notice that they changed Liners. Can't send back, non-returnable.

I've got 1:18" Superior Heavy .25 recently. I know nothing about changing the twist rate.

I have a 1:18 for my .25 600mm Crown, that I haven't installed yet. Right now , I can throw Nielsen 33.95 slugs , with the 1:24 barrel, at 985. I hoping with the new barrel , I will get better accuracy and maintain a velocity around 955. Fingers crossed.

 

[bigHUN]

Is that TR a 1:16 or a 1:15.5 because this what I am measuring

The Knockout mk2 33.49gr (with a small skirt) liked my std liner better than the heavy liner atleast. So now I wait for "normal" slugs to arrive so I hope Will do better.

The small red circle is 15mm
Each "group" are shot at different speeds from 880 - 965fps

Edit: there is 3 more groups but the phone resized the photo, but those groups are worse so....
