whisper groups @ 30 yards?
« on: February 11, 2010, 01:35:51 PM »
Hey guys & gals,
I am new to this forum, the wife bought me a whisper for my birthday which I thought was really cool, I have not shot a pellet gun since I was a teenager & at that time you could not keep it out of my hands. I  truly loved to shot that thing. Wow how they have changed! I know this is just an average pellet gun but I sure do like it. I took your advice & bought a trigger from tuna & it made a big difference.I also took your advice on how to hold this thing.  I have been through about 3500 pellets & the ones that work best for me are the  JSB MATCH DIABOLO EXACT HEAVY .177
 I have 30 yards to the back fence so that is what I sighted this in at. I am shooting 5 shot groups & they are all within an 1"  the best I have gotton are .5"  I am using a rest, a box on a couple of milk crates while I am sitting on a 5 gallon bucket. Is it possible to shoot clovers with this gun at this distance? I would like some input or any other tips you all might have. Different pellets that maybe I have not tried yet, anything or let me
know how you are doing with your whisper.Thanks all.

Welcome to GTA Matthew, very nice to have you with us.  

I don't own a Whisper so I can't really answer your question from  personal knowledge, but I've read many posts from GTA members raving about the accuracy of their Whispers.  I'm sure some of the GTA whisper owners will chime in soon.  

If you're looking for a good pellet sampler pack   http://www.straightshooters.com has some nice ones.  I'm sure if you try some other pellets you'll find a few that your rifle likes.  

And remember, if you hunt with that shooter be sure to post the stories and pics in the "Hunting Gate".  We just love hunting stories and pics..    

I'll be looking forward to your future posts and again.........Welcome    :)

Jeff

Matthew, a big welcome to the GTA forum and family.  Wow....  1" to .5" groups out to 30 yards is very good with an untuned airgun.  One of the reasons the "plastic" Gamos are not too too accurate further out is because of their lightness.....their rifles will "jump" abit more than the heavier ones.  Of all my Gamos....my Viper is the heaviest (I have already stuffed rags in all their hollow stocks)...and it's the most accurate.  You're already using one of the most consistant pellets...the JSB's.....so I hesitate to tell you to go try out other brands/types.

Since you already have the GTR-III trigger, the only thing to make the gun smoother and in-turn more accurate would be to go with a tune. Like others have recommended, going through the Straight Shooters Pellet Sampler might help you find a better pellet, however, if you find that the JSB's are still the favs for your gun, then a tune could and probably would be the way to get the gun shoot tighter groups.

If it ain't broke, - don't fix it. - Doubt from that distance you're gonna pick things up.

I recommend upgrading it to a gas ram.  I've got a Theoben gas ram on order from Airgunwerks for my CFX (which has the same internal dimensions as the Whisper).  In fact, I have Whisper gas rams in 2 of my 3 CFXes, which will all be converted to the Theoben gas rams in the near future.  The Whisper is a very nice rifle and is very accurate, but nothing beats a tuned, fixed-barrel air rifle.  The Theoben gas ram is supposed to increase power by ~20 fps, so I can't wait to get it and install it.  In the Crosman-Benjamin Gate, I wrote about my tuning an NPSS.  I get 1.5" groups @ 65 yards with Crosman Premier Hollow Points and the pellet goes halfway into 3/4" plywood.  At 20 yards, the pellets blow right through, especially the pointed pellets.  Stay away from the PBA Raptors because the pellet skirts don't expand to seal up the pellet to the bore's rifling and will leak like a sieve.  You also won't get the advertised velocities nor accuracy with the PBAs.  A really nice pellet to try are H&N Baracuda Match pellets.  They weight 21.14 grains in .22 cal. but they group like you wouldn't believe.  In the future, you might want to upgrade the piston seal with JM's tesla seal, deburr the inside of the receiver tube (so it doesn't gouge the piston seal when you install it.  And a tight seal will not leak and will give you full power from the spring or gas ram.  Good luck!

Hey Wai,
What does it cost to upgrade to the gas ram.
Do you need specialty tools to install.
 I tried those H&N baracuda Match did not come close to the jsb exact heavy .177
Thanks

Gas ram conversion can be done at PyramydAir if you send them your rifle.  The ram is $109, plus $25 for labor.  However, I do the ram conversion myself because I take time to deburr the inside of the my rifle's receiver tube.  I also upgrade my piston seal while I have the rifle apart.  I don't think PA will deburr and will just do the quick conversion and mail the rifle back to you.  Airgundepot has the same deal.  They won't send you the gas ram anymore because too many people who didn't know what they were doing probably screwed up their rifles.

The Theoben gas ram costs $149 from Airgunwerks and they'll send it to you to do yourself.  You'll need a spring compressor in order to take apart the rifle.

Welcome.

I've been doing most of my sight in with the Whisper at 15 yards indoors.  Late last fall I started trying some pellets out a 30 yards to see how well they'll do. With the wind gust coming around the house it's hard to tell. Shoots great out to 20 where it's more sheltered , but beyond that accuracy goes sideways alot !

Gun was sighted in for the 13.4 gr Jumbo RS. I set out some targets today, but the wind came up as a lake-affect snow squal line came through. I kept shooting anyway, but was getting some very wide "patterns" - I wouldn't even call them groups. I could hardly believe how much a cross wind was affecting them. They were 3- 4 inches wide by about 1 inch high.

Then I remembered I had some 18.2 gr Jumbo heavies. I tried those and they were still getting blow around sideways, but the groups were reduced to less than half the size of what the RS were doing in those gusts.

In the mean time, since the heavies were now sighted in, I wanted to see where they'd hit at 22 yards were the Starlings have been near the feeder. Didn't want to move the target rack closer, so I just aimed at weed stems sticking up out of the snow in the garden next to the feeder. Closer to the shelter of the house they did very well. Most went into the same hole in the snow bending, or cutting off the weed stems.

Then I remembered what we used to do for back yard target pratice as kids. I'd try cutting down one of the thicker plant stems. The pencil is pointing to the third shot - first two plowed a groove in the snow just to the right of the stem at the same level as the hole in the stem.  The three dents in the snow to the left are not pellet hits, they are foot prints from a stray cat.

Thought for sure the stem would fall over, but a 22 cal pellet meeting a tough 35 cal stem ....

Anyway, I had a good laugh when I saw that hole open up as I was looking through the scope.  

At least at 22 yards the Whisper can be accurate. If I get a calm day I'll try some groups out at 30 yards.

Where would one procure a spring compressor, I like to do things on my own( cheap and like to tinker). Also, anyone care to expound on the theoben vs crosman nitro gas ram debate?

Well, according to the Theoben dealer, their gas rams are supposed to net another 20 to 30 fps from the rifle, if not more.  
As for the spring compressor, most of us here buy them from the guy who makes it:

And then there's this one:

or they build one themselves.

I have a gamo hunter with nitro piston and big cat with spring and the Hunteer outshoots the Big cat all day. I went down to the swamp where i shoot and stretched it out to 60 yds on steel silhouette and hit 1/2 in group at 30. Lots of tree and stuff so not alot of wind but it does cut through at a couple points on the trail. I like the nitro piston over the spring anyday. ANd the weight of the wood stock over the synthetic also helps manage the movement. My favorite pellet is by far the JSB exact rs 7.33 gr and HN Barracuda match in 10.64 gr is very close 2nd. I have 4 more tins coming from both manufacturers in 8 to 8.4 gr. Invest in a chrono graph and test all your pellets through there and pick the most consistant velocity. I got the F-1 chrono fo r 77 bucks and you need the light kit for shooting indoors. the JSB had the smallest window 929.5 to 936.6 and hold the tighest groups. the HN were 802.7-812.7. I first chose the highest avg velocity for the most power down range but then learned that a 70 fps spread makes them inconsistant down range. You can have all the power in the world but it still wont kill anything if you cannot hit the target. I was shooting out of a lawn chair so was probably more comfortable than sitting on a bucket. Its also more supportive and adjustable. When you get in your shooting position close your eyes and relax then look where you are aimed, thats probably close to where you will hit. The lawn chair will help you wiggle a little to get the natural point of aim on the target you want. That way you are not trying to hold the rifle on target it is on target and just sit there while you are relaxed. If you try to hold the rifle on target you will never be able to hold it the same especially after breaking the shooting position to reload.

WHen I get the Money freed up I will send the Big Cat in for the tune and will fill the stock with foam to  see what happens. Cant wait to see how accurate I can get it!

So my top 4 that might help.
Consistant ammo.
Comfortable shooting position
Good natural point of aim.
Tune or gas piston.  

Hope it works out for you.
