Hw100 Tuning And Vid

[Gary73 62]

I did a little tuning on the hw100kt in .22.

 

Set the reg pressure at 90 bar and power at 619-625fps. Extreme spread is now 6fps using JSB exact RS 13.43gr. The good thing is that JSB heavy and Jumbo's remain within the 12ft/lbs limit and are slightly more powerful than the RS. Before they were 0.5ft/lbs maore powerful now about 0.1ft/lbs more so it looks like the tune has levelled the power out. Getting 96 shots at full power from a 200bar fill.

 

I fitted the Hw100 tuning springs etc which has reduced the twang/ping. I also used the reg tester they sell.

 

Just converted the garage to a downstairs utility which now gives me a full 30 yards at home.

 

A little vid to show accuracy and I am quite happy with the tune up. Can't decide if it needs a click to the left being 1/2" per click at 100 yards so 1/4" at 50 yards.

Tried the the Steyr Lg110ft today as I have not really used it in ages.

 

Gave the barrel a clean, set it up with 7.33gr Faps at 840fps avg extreme spread 5fps.

 

Compared to everything else it is so dead to shoot, the trigger is years ahead of general hunting rifles etc.

 

The Bushnell elite 8-32x40 is a gem optically. The steyr has a .177 Weihrauch barrel fitted 1/2" threaded and silenced.

 

I really struggled to get comfy but even so it delivered I have no doubt if I used it for a while and got my position and form sorted the groups would really tighten up.

 

I should really trade it in for the hunting version.

 

Anyway 5 shots 30 yards the blue bull is 7mm edge to edge. Great to have a quiet house and a wind free 30 yards.

Nice, I hope one day my 100 will shoot like that

Your 100 should shoot like that at 30yrds with the right pellet

[Gary73 62]

Its all about getting a totally wind free environment and a stable comfortable shooting position and the whole pellet and rifle combination right.

 

Throw in even the slightest of breezes and it can really turn quite poor.

 

I would love a trip over to the North West and the indoor 75 yards ranges, it would be a real eye opener in relation to which pellets really are the best.

 

30 yards gives a slight indication but 50 yards is where I notice the real compatible pellets shine.

 

I might get the steyr cerakote'd olive green and use as a hunting rifle or PX for an FX.

Spot on Gary. I test mine the same way.

Mine shoots like a shotgun at present, looking forward to it going away, should come back a new gun

HW barrels ain't the best more so the .22 ones.

 

Nothing an internal polish and re-crown can't sort. Sometimes chopping the choke off helps them I hear.

 

I think 90% of the problem comes from people claiming single hole groups at 55 yards, then someone tries to replicate and unless the conditions are excellent its going to be difficult.

 

I cannot replicate the above outdoors on a normal British day.

[Rabid 1,936]

2 inch groups at 20 yards........

If everything checks out in terms of scope, nothing loose etc on the rifle. It could well be the barrel.

 

Normal outdoors at 35 yards would be 3/8" ctc or 1/2" edge to edge. Good days it will be better.

 

But to be honest how often is it perfect and you have a bench to rest on in hunting conditions.

[Gary73 62]

Even the BSA R10 super carbine in .177 can do it with JSB exact heavy 10.34gr pellets.

I have a problem with mine, power is up and down like a yo yo, wheels are in motion to get it sorted though.
