Barrel length for spring rifles.

[Rapidnick]

Nick, I thought that venom used to sometimes reduce the barrel length (if it was a good HW barrel) by reducing from the breach, thus retaining the factory choke - however I also believe that Lowther Walther barrels were sometimes mounted in the original HW breach on other commissioned projects.

When pioneering design, many things are done.

My understanding was that Venom/V Mach -and SFS for that matter- shorten the barrels from the muzzle end thus unavoidably removing the choke. Shortening an HW barrel from the breech end strikes me as being an incredibly difficult task but what do I know? Perhaps someone from one of those could come on and tell us?

How are the facts regarding barrel volume VS shotcycle? I would think that a longer barrel gives a longer lasting cushioning effect for the piston?

Up to a point it does (second fwd stroke), but once it gets too long, the volume dictates the pressure drops too low to dampen...

I know that you said no FAC sir, but my Venom 80 has been chopped at the muzzle. In fact , I was told that it's the first thing they did at Venom, was to remove the chokes. I always thought that it would ruin the accuracy, but I can assure you it doesn't. By the by, I've just got back a chopped down and shrouded barrel from vmach, again removing the choke, so once I get some range time, I'll let you know if it's an improvement from its original state, pre- chop...

P.s. 12" is more than enough in a springer IMO

My understanding too. I doubt that it will be better than pre-chop but providing it isn't worse then you should be content.

Note sure if you guys have seen this... http://www.sportwaffen-schneider.de/...ducts_id/21791

Thats a 16inch screw cut HW35 barrel, I have one here, i swapped it onto a standard 19inch action and compared like for like, i found the choke less tight, the barrel was accurate with a greater range of pellets and with the choke being less tight it produced more power (plus it was shorter)
Read a few places the crimped end of a HW barrel makes the choke tighter to the top..so inconsistent...the screw cut ones just seem better to me.

As rapidnick said the Fenman was a delight to shoot, it was also fitted with a moderator which made it into a carbine length gun easy to cock and a very fast lock time, Wish I still had mine.
