s1k numbers (long)

Okay GTA members

I don’t know how far off these numbers are, but I hope it is close enough to have some meaning.

I’ll start with .177 cal then move on to .22 cal.

I chrony my Shadow 1000 that is stock and my tuned shadow 1000. The stock s1k has over 3,000 shots threw it and the tuned s1k about 1,000.

Using JSB Diabolo Match 8.2g, Gamo Master Pt 7.9g, and Gamo Tommyhawk 8.5g I shot 10 shot strings for the following average muzzle velocity:

Stock s1k at the muzzle was:
JSB Match Diabolo 878 fps
Gamo Master Pt 897 fps
Gamo Tommyhawk 887 fsp

The tuned s1k at the muzzle was:
JSB Match Diabolo 881 fps
Gamo Master Pt 907 fps
Gamo Tommyhawk 897 fsp

After figuring out the ballistic coefficient for each pellet, I use these velocities to figure out the velocity and ft-lb at 10, 20 30,40,and 50 yards. Just to see how far out I could get lunch for Ed (aka Shadow).    I know I can’t place a pellet in a kill zone at these distances, but I just wanted to see what the guns and pellets where capable of.

The stocked s1k shaped up like this:

JSB Match Diabolo at 10y = 782/11 (vel/ft-lb), 20y= 705/9, 30y = 638/7, 40y = 578/6, 50y = 523/5.
Gamo Master Point at 10y = 842/12, 20y = 792/11, 30y = 747/9, 40y = 706/8, 50y = 668/7.
Gamo Tommyhawk at 10y = 821/12, 20y = 773/11, 30y = 730/10, 40y = 690/8, 50y = 653/8.

The tuned s1k shaped up as follows:

JSB Match Diabolo at 10y = 782/11 (vel/ft-lb), 20y= 705/9, 30y = 638/7, 40y = 578/6, 50y = 523/5.
Gamo Master Point at 10y = 842/12, 20y = 792/11, 30y = 747/9, 40y = 706/8, 50y = 668/7.
Gamo Tommyhawk at 10y = 842/13, 20y = 792/11, 30y = 747/10, 40y = 706/9, 50y = 668/8.


Using the stock and tuned s1k velocities, the results were so close, that I just called it the same for each gun/pellet combo. I’m not much good at telling a rabbit at 45 yards or one at 50 yards. All I know is I no see without a scope.

What surprised me was how much energy all the .177 pellets still had at 50 yards.

Using the data from the table “Suggested Minimum Energy and Velocity Requirement” out of “American Air Rifles” by J. E. House. If a Sparrows, takes 2 ft-lb, a Starling, 3 ft-lb, a Pigeon 5 ft-lb, and a squirrel 7 ft-lb, here’s what I figured on how far out each gun/pellet would still put Ed’s lunch in the pot or the BBQ.:p

Both .177 cal shadows could bring down a squirrel around the 50 yard mark with a well place shot in the kill zone.

Let me make it clear, I do not recommend shooting at live prey at these ranges, at least with these kind of guns. I know many of you ( I my self) have made kills at these ranges, but how many wounded prey got away. Way too much, even if it’s one.

Now for the .22 cal data. More or less the same test was made for a Shadow in .22 cal and a RWS 350 in .22 cal.  Pellets used were Gamo Match 14.2g, H&N Match 13.7g, and Meisterkugen 14.03. The numbers are as follows:

Shadow .22 at the muzzle was:

Gamo Match 14.2 – 667 fps
H&N Match 13.7 – 696 fps
Meisterkugen 14.03 – 678

RWS 350 at the muzzle was:

Gamo Match 14.2 – 713 fps
H&N Match 13.7 – 785 fps
Meisterkugen 14.03 – 770 fps

For the shadow 22;
Gamo Match 10y = 611/11, 20y = 553/9, 30y = 500/7, 40y = 451/6, 50y = 407/5
H&N Match 10y = 633/12, 20y = 573/10, 30y = 519/8, 40y = 469/6, 50y = 422/5
Meisterkugen 10y = 611/11, 20y = 553/9, 30y = 500/7, 40y = 451/6, 50y = 407/5

For the RWS 350:
Gamo Match 10 = 656/13, 20y = 594/11, 30y = 537/9, 40y = 485/7, 50y = 438/6
H&N Match 10y = 699/14, 20y = 633/12, 30y = 573/10, 40y = 518/8, 50y = 468/6
Meisterkugen 10y = 699/15, 20y = 633/12, 30y = 573/10, 40y = 518/8, 50y = 468/6

Again, I don’t recommend shooting at live prey at these ranges. I just wanted to see what my guns were capable of doing. I will do some longer range chrony test, when I have time, to see how far off I’m with this data.

In the mean time, Ed and Jeff will have to get their own lunch, not unless.. Hey guys, you want a PB&J sandwitches.

Hey, Glenn, don't take this wrong, but I think there's something wrong with your 350.  I never shot any of the pellets you tested when I had my 350, but the lowest power I got was still over 19 fpe, and with Predators, I got just under 25 fpe.  Either it really doesn't like the pellets you're feeding it, or it needs some help.  It may just need a lube, they're notorious for shipping almost bone dry.  Mine was.

Dave

Hey David,

You didn’t hurt my feelings. I think this 350 is a lemon.  When I first got it, it was still dieseling after 300 shot. I sent to have it tuned and after getting it back the only deference I could tell in the gun was that it stopped dieseling after 20 or 30 shot. The recoil is so bad on this gun that it has broke one airgun rated scope and has cracked the rear sight and knocked the blade off the rear sight.

I been thinking of seeing if I could find a weaker spring to tame this beast down or just sell it and be done with it.

How is the accurate  was your 350, David? I haven’t found a pellet the 350 likes really well yet. I’ve ran a Straight Shooter sample pack threw it, along with buying a few other brands. I have only been able to get a little smaller (.70 to .80) groups with this gun at 20 yards. Not what I call a hunting rifle.

Accuracy was fine, and the 2 best pellets I found were Superdomes and Predators.  Both shot to the same POI, which was a nice bonus.  The Superdomes are 14.5 gr., Predators are 16.5.  I was getting 828 fps/22+ fpe from the 'Domes, and 802/23.5+ from the Predators.  That was right after I got it, the numbers went down as I shot it, I finally opened it up and lubed it, as I said earlier, it was practically bone dry.  That helped a LOT, the numbers went up, don't remember the velocity, but I had a Predator string that was something like 24.97 fpe.  I did notice some roughness on the piston seal, if I'd kept it, it would have gotten replaced.

Mine recoiled a lot, but yours sounds like it kicks worse.  I never broke anything, and once I got the BKL scope mount, I never had a scope slippage problem.  Come to think of it, I had the Leapers 3-12x44 full size on it just before I sold it.  That was in an Accushot 1 pc. mount, shimmed with film.  No locktite, but I did hang the stop pin over the front of the rail.  Nailed a starling at almost 60 yards with that setup, just before I sold it.

Since nearly all of my shooting is at paper, I finally realized I didn't need a 24 fpe target rifle that really wasn't much fun to shoot.  So I sold it and got my HW 77.  Now THAT'S a target rifle :-)!!  And it's already picked off a couple of starlings, as well.  

Who did the tune on your 350?  Have you talked to them about it, what they did, any ideas why it's still such a beast?  I will say, people seem to either love or hate their 350's, I don't know if there's a higher than normal percentage of "lemons" or maybe it's unreasonable expectations.  I know it wasn't what I expected, but at least it cured me of "magnumitis".  I've heard of people detuning them, but it seems to defeat the purpose to me.  If you still need the power, maybe you could sell it or trade it for a 48/52.  If you don't need the power, and prefer break barrels, sell it and get an R9.  I can just about guarantee you won't be disappointed.  I planned on replaceing my 350 with an R9, but while researching the various options, I stumbled across the HW 77 and just had to have one.  Gee, guess I got a little longwinded.  Good luck with that 350, and keep us posted.
