Btas hw100k t .177

[C3PO_1]

Hi All,

Yesterday I took delivery of my Ben Taylor-tuned HW100. Ben's given the internals a good working over, as well as supplying the new cylinder and new regulator giving more shots, flatter curve and the end of the "power creep" issue. I've fired a few shots to roughly zero the scope and she feels vey good.

Not dramatically different to before but I'm sure I'll notice things once she's used more [my guns don't do snow/rain/hail/drizzle/fog]. The weight, of course, is down with the lighter cylinder and the shot count has increased from ~ 55 before to 70 now, the power curve is totally flat ad the "power creep" issue is eliminated.

Only downside is the lack of the manometer to view the pressure and the lack of a plug to protect the cylinder from dust intrusion where the filler probe goes (I've got one coming from Steve Pope to sort this). Here are some rough pictures:

Can you have the same job done, but without the cylinder?
Should be cheaper and if you like the weight (As i do) you win all round!

when you say "Flatter curve"...does that actually mean NO curve as it is regulated?
Regards Mike.:D

[C3PO_1]

Yes indeed ... I mean "no curve!" I did ask about using the exisiting cylinder and ws told it could not be done because the regulator sits in the cylinder.

[blackscale]

Thankyou!
have you any idea how much weight it has shed?...mine is the 's' so the current weight is no good, i am interested in the difference!:D
Mike:)

The HW100 shouldn't suffer from any noticeable power curve in it's standard form. It has a regulating mechanism of sorts, straight from the factory.

It is my understanding that Ben fits his own design upgraded regulator, does some internal improvements and painstakingly sets up the gun for optimum performance (which is something that the gun factories don't have time to do - it can take some hours of tweaking to get the internals properly balanced and optimised).

Cheers Fluffy!
I love the weight of the HW100 i bought, I haven't had a chance to test it's consistency yet but it is certainly accurate :D:D

Not even sure it is worth 'free floating' yet...Didn't think the regulator was in the cylinder?
Maybe what Ben means is the old cylinder won't be compatible with his reg!??

Mike.:D

The HW regulator is not inside it's cylinder; it's in the front action block.
I don't know where Ben puts his reg.

I removed the barrel band on all of my HW100's.

Then he puts his own in his cylinder

Hi C3PO.

Glad you like her. Mine does the advertised 70 as flat as you like.

I still find the HW100 experience a bit odd. They are so quiet, you only realise it is a full power air rifle when the pellet hits the recipient/target.

The old HW maggies are just shredded (as would most pellets be) when they meet a knockover.

Are you still using the maggies?

The barrel bands look swish. Mine was given the GinB treatment by Ben, which was designed pre Oi barrel band, so it does not fit.

Mind you, as Fluffy said, mine also had long since gon west (well, actually North, I gave it to average plinker).

The local tree rats are in for some strife. I only saw 2 this morning, the first one of which bit the...err...leaf litter courtesy of Mr Taylor and mr HW.

The other one was way out of range and on his way home.

Enjoy. It is money well spent;)

Hi Parabuteo, yes really enjoying the rifle and you're quite right about the ultra-clinical nature of the HW100. Did a few chrono tests yesterday and the rifle hardly made a sound -- except for the thick thud of the pellet into the ground! And yes I'm still using Weihrauch Magnums, superb pellets for my gun. The squirrels had better watch out ...

[C3PO_1]

One drawback of the FX cylinder is that -- rather inexplicably -- it doesn't come with a plug to prevent dirt from getting inside. Nevertheless,for £14 I bought a suitable plug from Steve Pope at V-Mach and a perfect fit too it is for the unit. One top tip: always keep the filler probe and plug "O" rings very lightly lubricated with grease because if they dry out and fracture, the bits will lead to havoc inside the chamber.

Only 15 more shots from it being regulated?

[C3PO_1]

That's a 25% increase in the number of shots, not bad at all.

My full length .22 does over 200 shots now it's been fine tuned!;):D

Did some testing today with the new rifle and getting around 72 shots at full power before a sudden drop off from the regulator.

I set up a target at 46 yards, which is probably nearer 50 yards considering I was shooting uphill. Also, there were two sets of random cross-winds: the first at about 80 degrees to the path of the pellet for the last 15 yads of flight, and the other at about 170 degrees, giving it a bit of random tailspeed.

Pellets were unassorted HW Magnum .177 @ 10.1 grains and very well lubed (yes, I know not to soak the tin of pellets next time with 10 squirts of the Napier lube :D)

Anyway, results are below ... sorry for the blurred imagery!

The main problem I had was that I could not keep the crosshair steady exactly on the centre of the black circle (that's a 5p piece BTW), even with a bipod there' a bit of wobble. What I did was kind of guestimate the point where the wobble would intersect the centre and hope for the best.

C3PO, could you tell me where you got the front sling swivel stud from? Is it a standard item or is it made up especially for the new tube holder?

[C3PO_1]

The front sling swivel is the same one I had when I bought the HW100 a year ago from the gun shop ... they fitted it there and is just the standard stud to which attaches both my bipod and / or sling. The blue band is a bit of BT bling which I had fitted with the BTAS conversion.

[C3PO_1]

Ok -- had the BTAS 100 now a little while and thought I'd give a bit more feedback. Not long after getting the rifle I noticed a lot of air escaping from the cylinder after a certain number of shots ... just completely decanted. Anyway, sent the rifle back to Ben and he refilled and said nothing was wrong and kept it standing for a few days to check leaks. The rifle came back to me and after a zero-ing session it happened again! Could not believe it -- wrote Ben an email -- and thought the rifle would have to go back again. Well, my beta-testing side came out and I decided to refill back to 230 bar and do a test number of shots. Shot after shot and all was fine, in fact only got to the decanting stage at around 78 shots.

The moral of this story is: I am an idiot, it's official. I had grossly under-estimated the number of shots I had fired during my previous sessions, and realised how much I had relied on the pressure guage in the old HW cylinder before. Suffice to say there are no problems with the rifle and it's a credit to Ben's patience.

One other thing: I got my 12L, 300 bar bottle recharged at the local divers' shop and it was down to 220 bar, so needed filling clearly. Got home and plugged in the 100 and opened the tap to where I normally charge to and the thing rushed up to 270 bar within a couple of seconds!! Bloody hell, I quickly -- but carefully -- removed the filling probe and dried-fired 20 shots and brought her back down to 200 bar. Lesson learned there.

Another tip: make sure that the "o" ring seals on the filling probe (and the probe protecting the air inlet hole) are kept greased because if they become dry they can get brittle and end up in the cylinder. This applies to all HW 100 models.
