HW 45 Black Star

[Pjw18]

Welcome back Bilko,
I have the same pistol , still deiseling after 1 year 😫
How I see it is You do 2 things ,
1 shoot the thing till it stops and then
2 Take it do bits and degrease it .

Yes like Me You don’t want to do that , it may be the only way ,
hopefully someone else turns up with an alternative answer and tells You 👍

They all do it.
Two hundred shots can bashing to run it in.
Then try targets.

If it’s .177
You will get better results on half cock.
You also have to set the sights to the power you use.

Oddly the high power shoots lower.

They are easy to strip. I put a TBT kit in whilst it was apart, degreased and cleaned. No more dieseling.

Stripped mine, cleaned it - reassembled it practically dry (which I hated doing) and it still dieselled
I cured mine by selling the piece of crap.

I've done the TBT kit in my .22. It's quite nice. It is relatively easy to break down. Good luck.

I've got the silver star, has upwards of 500 pellets through it and it still diesels like a bitch most shots. Made the mistake of shooting it in the garage for the first shot, nearly deafened me and trashed the pellet catcher I was using.....

My Silver Star 0.177 was desieling every couple of shots. Fitted TBT kit today and it's totally transformed it. I totally cleaned away all the original grease from the inside of the cylinder and piston. I removed 2 coils from the spring then retrimmed and ground where I'd removed the coils. Lightly greased (with the TBT grease supplied) the back of the piston and spring and re-built using the TBT kit. The pistol is now easier to cock and shoots with less recoil and no dieseling. Chronoed at 514 fps (4.95 ft/lbs) using JSB Exact 8.44 grains. Variation of 4 fps over 20 shots. Accuracy at 10 yards is now on a par with my recoiless FAS 6004.

Just now tested over chrono again. First shot desieled and read 557 fps then settled to around 515 fps for next 20 shots with no more dieseling shots.

Cool. The HW45 is in my top 5 pistols for sure. Yeah ,isn't that kit nice. What I took from that is now on rebuilds I slip in nylon washers where I can. Reducing some metal on metal. Just got a nice assortment of nylon washers from Amazon. It adds a bit more compression on one the spring. The preload.
I'm resealing my Diana mod. 10 and I've slipped in some at the bottom of the spring guide tubes where the springs rest. I finally got around to mastering the reseal for the Mod's 6 and 10 which have the Giss system. Of all the different types of recoil containment I think the Giss does the best job. They are nice to shoot,a little strange even at first. I always like a nice spring piston recoiler though. Have you noticed the smoothness in the cocking and firing ? It's worth the light power reduction when the spring is shortened I think.You gain some back when the nylon washers/bushings are installed. I've never had much dieseling from my 45's. Right now I've got all three calibers. I'll be selling one soon,the 20 cal. I'm putting a bunch of items up for sale in the next day or two.10 or 12 pistols and some assorted hand grips and barrels. One barrel is a .22 cal. for the HW 45. .....Well I'm rambling....Gonna go run up to my pistol nook and shoot before the
Mrs. gets home. Chow

Good evening folks,

A returning member here.

My birthday was a couple of days ago, wifey bought me a new Black Star with the tru-glo sights.

Have to say, it's much better than the usual pistols, ie CP88, 240 Magnum etc but I have a concern....

The only thing is, it diesel's like a pig! The odd shot is clean but mostly produces visible smoke. Crack's like you wouldn't believe!

It really difficult to get any meaningful results on a paper target, to sight it in. I don't suppose my "wand like" technique is helping much but I can't help but think the dieseling isn't helping?

Has anyone gone though this? I don't particularly want to strip a brand new gun and wondered if anyone here had any meaningful advice?

Your thoughts?

They all do it.

Welcome back, Bilko.

Re getting accurate with the '45. It's usually just a case of spending time with it and getting to know how it prefers to be held rather than the dieselling affecting accuracy. Keep practising; you'll get there.

Re the pistol shooting lower on high power. This is just the result of muzzle flip in reverse, so muzzle DIP, with the piston travelling back towards the shooter on the compression stroke, causing the muzzle to dip down.

The dieselling generally won't hurt anything. One thing you can do, as much as it goes seemingly against the grain, is to dry fire the pistol a couple of times to help form the PTFE seal to the cylinder. PTFE has no memory and "creeps", so will expand to, hopefully, form a better seal.

Fantastic pistols with fine accuracy, great trigger and bags of character. Enjoy.

Thank you all for your advice.

I'm very tempted to strip it and clean everything of lube because the dieseling is horrendous!

However, the warranty issue is stopping me atm.

I don't quite know if I'm ready to dry fire a brand new pistol, your right... That really does go against the grain...

Tried it again every day this week, in the back garden at about 6 meters. I would say every 4th shot is clean, then plumes of smoke for the rest...

Smells nice though...

Again, my thanks to you all.

As others have said dieseling 'normal; with these.

It's NOT the cause of inaccurate shooting tho.

Just spend a lot of time getting the 'feel' of the gun and don't feel the need to fiddle with sight adjustments at this stage. Once you find that your shots are starting to end up on the same place is the time to start thinking of sight adjustments.

Two 'common' faults that people using these pistols are their grip and 'anticipating' the recoil.

Your grip needs to be nothing more than firm (and consistent) the gun isn't going to jump out of your hands so no need for a stranglehold on it.

'Anticipating' the recoil is not uncommon and links in to having a firm and consistent grip. Even a slight 'anticipation leads to an involuntary, albeit small, change of grip. Remember - the gun sounds loud and impressive when fired but the recoil won't make it jump out of you hands.

[WinerackHWModel]

I have the silver star variant and it has just calmed down on the dieselling after about 500 shots. The first 10 it was smoking like a live fire after being shot, I’d be lying if I said I didn’t enjoy it 😜

[zephyr]

I have the 45. I put in the TBT plastic bits and reduced the length of the original HW spring and polished the ends - a lovely smooth and reduced recoil action now. Despite very little lubing of spring and guides/“top-hat” (and a few thousand pellets) it still diesels for the first few minutes of each shooting session.

Agree with people above, grouping is affected by hold. I have lightened the trigger weight, fettled the sears and re-lubbed them, the result is a very nice and consistent trigger action.

[BigEars]

Dieselling and smoke are all part of the fun of HW45 shooting. Your wife is definitely a keeper. I had one in 0.22. the pistol , that is.
