HW35 The Collectable Weihrauch

[coburn]

Just retried it over the chrono. Its averaging 9.5ftlbs with Hobby but only 8.6ftlbs with Superdome. I really need to get round to giving it a strip and lube. I suspect a lube problem because in my string of 12 shots with Hobbies its first shot was 618 followed by a gradual decent to 597fps. There was no dieselling or smoke at all.

However whilst I had the stock off I noticed that the spring guide appears to be a synthetic material! I was under the impression that HW's were fitted with those horrible rolled steel ones. Can anyone enlighten me.

Hi Coburn
Chambers show a synthetic spring guide for the 35, I don't know if this is the standard fitment now.
With your gradual drop off in power it may be worth checking the breach seal for leakage, these can be shimed out with paper or thin card if needed.

From your chrono results it seems your gun is only 50 to 70 fps below the 12ftlbs limit with Hobbies. I would strip, clean, and lube the gun, I would also change both seals (£10) and see what it does then.
On second thoughts I would change the breach seal and just inspect the piston seal for wear and fit as it wouldn't appear to be that bad from your chrono results.

If you need a tuning kit for your gun, Bonnie and clyde has just put together a kit for the HW35, check it out on the revue section.

All the best Mick
