Back from The Snowy Mountains last night. The test results on the new JSB King .25 pellets lived up to my expectations based upon the "one holer" 28 yard test I reported last week.

Here is the second sub inch group shot on Saturday
( of five groups shot in total, 4 in the morning and this one - the only group shot in the afternoon at 100 yd, why shoot another :<) ?). <br>



Yes, the outlier was the 5th shot but it wasn't pulled, it just went there. The first 4 shots measure just 0.30 inch 7.62 mm CTC.

Stats: JSB "Kings" .25 cal 25.4 gr shot at MV 880 fps for 44 fpe from the JB OZ 1 BSA .25 cal Hornet. Bushnell 6500 Elite 6.5-16 scope set at 16 X power.

Below: The Moffitt range with the target set at 100 yards (laser) and the BSA John Bowkett tuned Hornet with its replacement 23 inch .25 cal barrel.



Below: This one was the best of four groups shot in the morning.



I did a BC test using one chronograph set at 6 ft and then at 50 yards and the average of 10 shots at each range. The result was BC 0.039 at the altitude of 4050 ft which corrects to 0.034 at sea level. This is very good for such a short-for-diameter diabolo pellet.

A contributing factor no doubt is the consistency of the JB OZ 1 regulated Hornet and the consistency of the weight of these pellets. I shall post a 25 shot string some time later; shot while shooting five of 50 yard groups. I have never seen a better one. 25 shots with an extreme spread of just 6.2 feet per second.


We seem to have a new competitive player in the .25 cal stakes ... and I think, the first sub inch 100 yd 5 shot groups reported for the .25 calibre, which has often been put down as less accurate than other calibres. The 100 yd MOA has now been shot with all the small calibres .177, .20, .22 and .25.

Pellet design and quality and that of barrels and rifles, make the differences - not the calibre itself.

Hope you enjoyed sharing this exciting result with me ... Kind regards, Yrrah.

Great shooting Harry.
I struggle to get groups like that at 40 meters!
I think I should buy some sandbags.

Thanks Makka ...... some kind of rest is essential if one wants to find out what a pellet and rifle can do. There is still an element of shooter in it of course and wind reading to trigger each shot at the best instant helps. You might be amazed at what you could do with my gun and pellets

Kind regards. Harry.

Hey Harry,

Nice groups. I miss my Hornet and would certainly like a .25cal of any sort, I may look at getting one in the near future. My .22 Hornet was enough of a hammer and was seriously an accurate piece of gear. I would shoot spent .22lr cases off a log at 45m with a 20x scope, it was an awesome rifle and I loved the cocking mechanism. One in .25 would be sweet. I never chronied my Hornet but I have cronied my AA RN10 Titanium with Joe Korick regulator. It got an extreme spread of 5fps over an entire 42 shot fill. That's not a miss print, it was an extreme spread of +/-2.5fps for the full 42 shots. I wish I could find the string but I can't work out where I saved the file on my computer .

Where did you get the pellet tin with the foam liner like that? I might make one myself but that looks like it came like that. I could do with one of those.

Mmm.. am I looking forward to getting back to Aus and having the space to do some long range shooting and offhand practice again. Toys to buy soon.

Cheers, JD

That is a wonderful spread JD ... The % of MV for mine is 0.70 % which is a better way to describe it. What would your AA MV have been? If it was shooting above 880 fps then that spread is even more impressive.

The foam lined tin and the plastic slip cover came to me from JSB with the sample pellets. The former can easily be duplicated with a strip of foam cut to size placed around the inside of the tin and two normal patches for top and bottom. The latter is a gem. No more taping tins unless one can't break the habit. The slit holds the tin together - no more spilled pellets. Not sure if they are for sale ... When are you coming "home"? ....... I had a month fly fishing Tassie through February. The fishing was marvelous still ...... Kind regards, Harry.

Great shooting Harry! I bet the boys at JSB will love those performance results.
Well that,s torn it for me..............Now the darn .25 Cal bug is biting!
cheers, Ray.

I'm now looking forward to how this accuracy performs with the extra thump on the bunnies and maybe a fox or three. ..... and looking forward to the even heavier .25 JSBs to come ..... Now that I know how these Kings shoot they won't be wasted on a lot of targets ... some ... not a lot. I'll have my order in to Lewis/ Rob
Kind regards, Harry.

Hey Harry, home will be by this Sunday. Looking forward to it. I'm just trying to sort out options with my rifle at the moment. I'll be leaving it with a friend until I work out the details of its sale over here. Sad times but I'm not quite prepared to go through the import process at this stage. Should have sorted a B709A a while back and taken it as checked baggage, but think it will just be easier to sell it and buy something with more power in Aus.

For interests sake, my MV was 870 with JSBH .177's so guess that makes the spread 0.58%. It really was working very well. Nice to know they are spitting out the front nice and consistently, but as you know you have to have the barrel and pellet and shooter to complete the deal. My rifle shot exceptionally well. I got to shoot it in a 51m underground tunnel and it did 3 consecutive 5 shot groups of .4", .3", .25" so it could put them down there ok. Just thought I would post a comment about my MV spread out of interest, as an indication of what these regulators can really do.

I was interested in the tin as I was wondering if maybe all the JSB tins were going to start coming like that(been a while since I bought a tin) . Wish that was the case, it would be nice. But I can make one for sure (and will do). My current tin is 1/2 a JSB tin with a buttler creek flip up scope cap on it, works great but I think I'll fully pad out the insides as well like yours. At the moment it's only got 2 pieces of foam in there.

Anyway, nice to see the results of the JSBs. They just seem to work in so many rifles.

I can see why you are sad to leave that rig behind
Well, think Steyr 110 HP. Rob Potter has them.. depends of course on what you want it for .. Safe journey .. Kind regards, Harry.

The steyr is the one i have my eye on Harry. Trying to make arrangements to get one in my hands. Main reason this one is going to go unfortunately. I will want a little more power and more calibre back home.

All the best.

I'm not in the marketing game but:
A mate has a 110 HP .22 and it is a beauty. It pegs level with my rifles for precision. I like single shots. The loading directly into the barrel without a probe is a ++ feature for me. The transfer port is in the "bolt" head. It has a stainless barrel and all weather stock. The stock is certainly functional but not particularly attractive. The reservoir detaches for filling but I didn't find that a hassle. From memory it gets 40+ shots at 30 fpe and the consistency is excellent ....... I would own one if I didn't have the almighty Excalibre ... it is a higher class rifle though but I am sentimental and loyal to a rifle that has shown the way in long distance shooting ....... I'll shut down for a week now ...Kind regards, Harry.

Nice shooting Harry.

Looks like your having quite a bit of fun!

Keep the posts coming.....I still love'em.
