HW30/R7 barrel length

[peaceful_ruler]

Why does my least powerful springer(7 fpe HW30S) have a longer barrel than my most powerful springer(14 fpe HW97K)? Has anyone tried shortening the barrel of their HW30/R7 and what were the results? If I can cock it with only my pinky now I'm pretty sure I could still cock it easily if it was 2" shorter.

You can cut it if you like, but know two things.

First, That gun will likely feel butt heavy with a shorter barrel. IMO they normally feel a little butt heavy.

Second, The accuracy will tank if you cut the barrel without replacing the factory choke you cut off. Weihrauch uses two chokes one in the breech area to size the pellet and one at the end to straighten out the pellet before it leaves the barrel.

Other than that, feel free to cut it.

Because of the iron sights probably. Longer sight radius = easier gun to shoot accurately.

Barrel length has very very little effect on power with springers. Especially low power springers.

This may be overkill but these are the measured specs from my HW95L .22

Moderator weighs 4.32 oz, 122.6 g, 1892 gr. Moderator is 6” long and female threads start 1.7” in from beveled end of Moderator. The thread is 3/4" long & 1/2" diameter with 20 threads per inch.

Barrel length = 15.75”, 400 mm, from end of moderator to breech block end. HW95 barrel is 16 mm diameter.

Barrel without moderator = 12.188”, (12-3/16”, 309.575 mm), from thread end to breech block end.

HW95L total rifle length = 41.875”, 1063.625 mm, from end of moderator to butt center.
LOP = 14.25” trigger to center butt. WIN M70 30-06 = 13.875", CVA Accura V2 50 BP = 14.5". Note - LOP = length of pull measured from trigger to center butt.

Hmmm...I new there was a choke at the muzzle end and that was my largest concern. I'll take your word for it that the breech end is also choked...although I've not really seen evidence of that when I clean the barrel. Maybe it is choked to a lesser degree than the muzzle end?

I suspect you are right, though, because the 700mm CZ barrel on my Veteran Taipan is noticeably choked at both breech and muzzle. Nevertheless, it does shoot slugs quite well.

Push a pellet through it with a brazing rod or stacked bamboo BBQ skewers and you'll feel exactly where both chokes are. The breech will be about 2" in and the muzzle about the last inch. The breech choke is created by the knurling they use to press the barrel into the breech. The front sight dovetail is crimped and that creates the end choke. Both are typical German deliberate duality.
