I am looking to build a slug gun in .22, trying to nail down the right barrel for accuracy...The general consensus should be unchoked for shooting slugs, however some people are shooting LW Choked with 23 and 28 Grain NSA slugs very well...I am trying to nail down the right barrel specifically for accuracy 50 yards plus with slugs, my choices are :

LW Poly 24" - Choked
LW Poly 24" - No Choke
LW Standard Profile 24" - Choked
LW Standard Profile 24" - No Choke
Weihrauch 635 MM - Choked
Weihrauch 635 MM - No Choke

Any first hand experience would be great, my mind says go with LW Poly 24" - No Choke as the best choice, will be shooting at 860 -900 fps, so high enough power, as I have heard that the Polys like higher velocities...

Thanks in advance for your input...
 
I'm trying to do the same thing in .25. When I talked to Steve at Pomona Airguns he said just go with the normal unchoked LW. If you wanted to get a 30" LW in .25 you could join the special order I'm trying to get ordered but I need 4 more for a minimum order of 5. If you read my post at that thread you'll see I spoke with Ernest at FX USA and he told me with the slugs the faster they went, the tighter the groups and we were talking about the LW not the STX. You will get a higher velocity with the 30" barrel so it should shoot better than the 23.8" barrel.

Barrel doesn't mind about the velocity, but bullets/pellets does. :) If I remember correctly, LW's polygon profile airgun barrels have less friction, so you get better velocities out of them.

One barrel option to consider is also LW's .22lr barrel. Some people are reporting good results with .217 slugs and .22lr barrels combination. Longest option from LW is 755mm/29.7".
