Folks’. let me know how this stacks up. I finally got to try some JSB’s, from the Sportsman’s warehouse. (Re-labeled)
I sighted in at 40 yards, and then set up a target at 90 yards, paced. Sorry, no range finder. First group of 10 rounds went 5.5″ Low with dead on hold. Group measured 1/2″ X 5/8″.
Next group went 1/4″ tall X 1 1/8″ wide. (Mild wind started from the west. Apx 5- 7 Mph. Calm for this time of year in Texas.
I am extremely pleased with the results. This is a bit tighter than I have been able to get with the Kodiak’s. Best so far for them at this range has been about 1 1/2″ t 1 3/4″.. But when the wind starts blowing’s as it always does around here until summer, the Kodiak’s are much more predicable. Shame they don’t shoot to the same point. They shoot about 4″ left, and 2″ lower at 90 yds. At 40 yds they are still lower by a good 1″ to 1 1/4, and about 1 1/2″ to the left.
So what say you all? Wish I had a bench, This was with the SS laid across a work stool, while sitting on the back steps.

Those numbers seem fine to me. The targets to aim for are sub 0.5″ at 50 and sub 1.0″ at 100, with the latter being more difficult, obviously. For everyday types of shooting though, as long as all of the shots go inside about 1 to 1.5 inches in an even spread then you should be good to go as that will cover all but the very smallest critters.February 25, 2008 at 11:49 pm #34896walkonkingParticipant
That will kill them critters.
What you need is what I use for shooting in the back yard. I went to the local thrift store and bought a camera tripod. Put a V on top of it and shoot from that seated in a chair. Not bench rest but deadly accurate.February 26, 2008 at 12:37 am #34901pilgrimParticipant
Adam, how did you mount that? I’ve been trying to figure that out with my camera monopod.February 26, 2008 at 12:59 am #34903
Thanks for the info Tron, I guess I am just expecting too much. I’m so use to the 17 HMR. Rimfire. She’ll do 1/4″ at 100. And is only made by Marlin. After all, Our guns do have Walther Lother Bbl’s in them. I’ll keep after it. I am going to hone the Bbl, and set up a bench. If this infernal wind will ever stop for a few minutes. On a side note, It hit 90 degrees today. IN Feb. !!! Unreal!!!!February 26, 2008 at 1:04 am #34905walkonkingParticipantquote Pilgrim:
I had the top to a shooting stick and then drilled and mounted a bolt to the bipod and screwed in the V supportFebruary 26, 2008 at 1:07 am #34907bodhisdadParticipant
Knife maker, i have spoken on these pellets before and i like them as a matter of fact i went to a sportsmans warehouse today and picked up a few tins> there going out of business and i got them for $10 a tin 😀 . dam good deal for a 500ct. of .22 JSBs. Am probably going back tomorow as they have some Ags and i’m going to purchase and resell. Can’t beat the price on them see another post on this later.
Wok, Sweet looking setup, i have a spare transit tripod and could use some details on what you did to get yourself that setup. Thanks in advance.February 26, 2008 at 2:47 am #34919teflontronParticipantquote knifemaker:
No worries. With an airgun anything under 1″ at 100 Yards is something to be very proud of for a 5-shot group and they are the kinds of groups that take a very good rifle, good shooter, practice and luck. Airguns simply lack the velocity, power and ballistics to match high-grade firearms at ranges of 100 Yards or so, but at closer ranges, such as 50 Yards, they can match them, and in many cases beat things such as .22LR.February 26, 2008 at 3:15 am #34922
I agree with Tron.
One of the really great things you have going is low vertical dispersion, which means uniform velocities. You can allow for wind much easier than curing non-uniform velocities.
An other observation is airguns with projectiles with B. C. s that start with .03 will never shoot with something twice as fast and with B. C.s that start with .19 or .23 like a 17HMR. The groups will always be something of a weather report. Relatively speaking you’ve got a smoking accurate gun. Your pellet gun almost shoots with a $1500 Anschutz Model 52 but with a little more wind, and can be shot in places you could not shoot the Anshutz, like at the pigeons living in the underpasses on Hwy. 190. Go make friends with one of the car dealers close to the pigeon roosts. They hate pigeons and will find a place to hide you while you shoot. Sometimes they even cheer. You’ve got the goods to do it.February 26, 2008 at 3:36 am #34924justforfunParticipantquote garytex:
The last time I thought about that is when I considered magnetic field deviations. Could you clarifies that comment?February 26, 2008 at 4:59 am #34938
Thanks so much every one! She didn’t shoot this tight at first. So I spent some time lapping the bore with Flitz polish, cleaned with goo-gone, dried with Alc. then lubed with fp-10, allowing it to soak for a couple of hours before patching dry.
I noticed that I miss typed. 1/2′ X 5/5″ Should have read 1/2″ X 5/8″/ It has been changed. The vertical string on one group being so tight tells me as you say Tron. Very consistent velocity.
Seems like there is a lot of movement in the gun being caused by the hammer travel and impact. I can only assume that this is from the heavy spring and long travel of the hammer compared to a Powder Burner. Where the hammer strikes in just a few milliseconds with a much lighter spring and hammer weight.
Yeah, popping pigeons on 190 would be a hoot. But Gang activity here has gotten so bad, that if I got caught, they would throw me under the jail.
We have an unbelievable amount of drive-by’s.. this is what has gotten me into air Gunning again after all these years in the first place. We were Incorporated into the City about a year and a half ago. It is still allowed for me to hunt varmints here and on several large acreage lands around me, but a new housing area has been built a few hundred yards east of us. There are so many drive by’s, and crime, that just about every time I went night hunting, hearing the report of the .17 Hmr, some one would call the police. So I would end up sitting on the ground, with bright lights on me when returning from the hunting fields. They would give me hell! Not to mention having guns drawn and pointed at me. Of course I would request the Supervisor. Eventually hone would show up and explain the the laws to the new rookies. (Man we go thru a lot of Rookies!!..) But it get old. Not t mention embarrassing.
The LDC on the 18″ SS is doing a fine job night varmint hunting! But it still isn’t a .17 Hmr, or a 22-250 by a long shot.
But I’m having a blast!!!. This Air Gun Stuff is way more fun than I remembered! I’ll bet I’ve gone through 3000 rounds in the last 2 t 2.5 months I’ve had the gun. How many years would that have taken me with a PB? A lot. There just isn’t anywhere left here to shoot!

Term “low vertical dispersion” referes to the horrizontal nature of Knifemakers group. The usual suspect for a vertical string type group (ignoring barrel vibration shaking the muzzel) would be differing velocities causing the point of impact to shift up and down. So it is good news to have low vertical dispersion. His groups are “weather reports”, affected by differing wind velocities blowing the pellet to the side. An interesting aside is that there is a slight (about 20 degrees) vertical component to wind drift which relates to projectile spin. Right hand twist gives slightly up POIs when the bullet is blown left. Or maybe it is the reverse. I knew this shit when I was shooting .22lr benchrest, but since 50 I remember less & less.
Poo. I’m so sorry things have gotten so shitty in Killeen. I am on the trail of a new Crow hunting spot near Bastrop where I could take a guest. All of my other local spots have some degree of “don’t get caught” associated with them. If it works out we’ll go.February 26, 2008 at 5:29 pm #34950riffraffParticipant
You are shooting groups at 90 yards that I have trouble achieving at 50 yards. Considering flight time of the pellet, I would have to be shooting in a vacuum to get that performance.February 26, 2008 at 7:24 pm #34957
What part of magnetic field variations were you interested in?
Treasure hunting with a MAD? Flying or sailing compass courses? TVMDC?
Seeking submarines? Iron ore deposits? The variations are endless.February 26, 2008 at 11:01 pm #34979
Sounds like Fun Gary!!!
Thanks Guy’s,, good to see where the Talon is stacking up!
