The HW100 T or K receives great write ups. However there is a mention of an "anti tamper" device when discussing the new rifle.
What is this "anti tamper" and does it prevent tuning the rifle to 11.7ft lbs. from the current so called "full power" from the manufacturers of around 11.3ft lbs.
Looking to buying one in 0.177. Saving hard. maybe have to sell "her indoors".
Generally the 11.3ft lbs would be more than adequate and should keep
you the right side of legal if a heavier pellet was used to test the rifle,
however, I cannot guarantee this. Moving it to 11.7 might just see you
the wrong side of the law with some pellets.
The Anti-tamper device is being fitted to most if not all PCP air-rifles
as far as I am aware and basically prevents the user from tuning the
The HW100 does have a tendancy for the power to creep, mine has
been both over and well under, so it can mean trips back to Hull
Cartridge for adjustment.
The rifle is a great piece of kit, best magazine system on the market, bar none, but with the fluctuating power, it can be a bit of a pain.
If you get one, pick up a Combro at the same time and keep an eye on it.
You can change my signature, but you'll never take my freedom!!!!!
The power of the new HWs is set at the factory, and the adjuster is superglued, and sheared off so it can't be altered. The problem is that HWs power tends to creep up as the parts wear in from new. If it exceeds 12 fpe, it has to go back to the importers, (often Hull Cartridge,) where they fit new anti tamper parts, and the whole cycle repeats itself. If you send an older pre AT rifle back for a service, it comes back with AT fitted.
Part of the fun of shooting is to be able to play around with your rifle's performance, (this is particularly true of FT shooters,) which is why I won't buy an AT rifle.
The ox is slow, but the earth is patient.
The POI change is minor and any quarry you headshot at sensible hunting distances are not going to be any more dead with 11.7 than 11.3.
11.3 FPE is an eminently sensible power setting. It allows for weather changes and pellet variations and for PC Dibble to test your rifle with whatever pellets he likes and you'll stay legal.
Frabkly if your rifle is doing 11.3 FPE from the manufacturer thne I'd say count your blessings. Most of the AA rifles seem to be coming out at 10-10.5 FPE.
Anything above 11.4ftlb is too high and would probably result in the gun exceeding 12ftlb in a police chrono check, once they crank up the central heating at the lab, lubricate the pellets and test it with the heavies.
Also bear in mind that most rifles can vary a little from shot-to-shot and it only needs one shot to exceed 12ftlb.
I set all my guns to 11.1ftlb and the rabbits don't complain.
But there is another way to adjust an anti-tamper HW100.
I only recommended it in situations where an adjustment is absolutely necessary - not for gaining a piddly 0.3ftlb over the factory setting. The HW100 is very good at doing that all by itself. Four of my five went "hot" after a tin of pellets.
