Polygon barrels for airguns

[Rapidnick]

With the lower energies at work in even the most powerful air rifles it just isn't necessary to incur the extra expense.

what do you mean for extra expences? Usually production of polygon barrels are less expensive than traditional

Really? Are you sure?

Yes, industral production of polygon barrels is generally cheaper than traditional land & groove profile.
Anyway, just received a mail from L. Walther and they suggest using traditional barrels for "target shoting"....

So, ....I have to keep my 25 cal HW 900 as it is (2" @ 30 yds) till Ben Taylor wonder barrels will be available....

Hey Roberto, would not blame the barrel for those groups. Can be difficult to shoot a gas ram accurately - even though 2" at 30 sounds terrible.

Scope OK? Maybe it's moving about inside.

Also removing the barrel may be less than easy, although having taken a look at your site, it seems that you know your stuff quite well.

Belive me, I tried everything possible to make this rifle shooting better...but no way. For this reason I'm thinking to swap the barrel, it's a sort of last chance.

Probably part of the problem is the pellet choice; in this caliber the market is quite poor, only the Diana dome 19.75 give acceptable groups. Other brands/models are simply useless.

Anyway .25 barrels on springers/gas ram are particularly pellet-fussy, especiallly if you go up with the power (I own also a terrible W&S Patriot same caliber).
On pcp irguns things goes different, I shooted a Rapid 12/250 @ 50FP and it makes beautifull groups with 30 grains Baracuda (up to 100 yds or so...).

Is yr HW90 FAC or 12Ftp?
In FACtrim they usually shoot terrible unless you let off some pressure!
They're over pressurized from factory!
They should shoot well with either baracuda or FTT.
If you stíll wish to change the barrel, buy another HW one. About 72 euro's in germany..

Thanks for the information.
