More questions,Please

I did not know where to post my questions but I am shooting a springer I felt like I might be safe.

1. Is there anything one can do to make a pellet shoot in a rifle that it don't like. I can shoot great groups with the high dollar pellets but the Crossman pellets look like I am shooting a shotgun. I ask because I have a good supply of the Crossman pellets. I tried to find an answer in the back post but no luck.

2. The Burris scope rings that can fix barrel droop. What are they called. Do they work well?

3. are there some guns that just don't like any pellet. I have a F4 that is having a good when all the pellets hit the paper(somewhere). I have cleaned,oiled. changed scope mounts and changed scopes and tried several pellets. It is fun to shoot if you don't want to hurt anything. Any Tips.?

Thanks and God Bless
 
sorry, I left out tips. The list of things to do or try is extensive, if you are a tinkerer you are going to have a ball; if not, not so much. You can start by using JB bore paste and bore bright on the barrel, never hurts and often helps. You can then try doing doing the brass washer mod for for your barrel pivot if your F4 has plastic washers. If they look like they're metal skip it and just work on the barrel first. Check the crown of the barrel and re-crown it if neccessary. You really can't shoot accurately without a decent trigger either. You can save a lot of money by doing this yourself. There are a lot of youtube videos and resources here to show you what I'm talking about. Have fun with it, and good luck!

Oh, and I love those Burris Rings on my powder burners but I believe that there too many variables with airguns and they are not dynamic enough if you want to move your scope to a different gun, changing the angle gets old quick. You could just get a 20 MOA base for droop or you could get some FX adjustable rings too. 
 
I would have to agree with the above post or posts now. Still for #3 you can push a pellet down and out of the barrel with a cleaning rod and then check it for damage. If it is damaged then there is hope by finding the part of the barrel with the problem usually a burr at the crown or lead. Fix it and the gun will likely shoot better. If the pellet pushes rather easy then find a larger sized pellet. I think H&N make some larger sizes.

One of these is probly what you are after. Someone makes a less expensive one but I can't find it at the moment.

Thinking on it, I don't know your experience level so I was leaving out the most basic stuff, but in case you are new at this, the very first thing to check is that all of your screws are tight and stay that way while you are shooting. And you need to hold the gun the exact same way every time you shoot. Some springers like to be held loosely, others tightly, experiment, look up "artillery hold." Some people swear by it, others at it, but you need to find what works for you and your gun, they are all different.
 
Scope parallax is what bit me. If you're not aware, it can drive you nuts. Just a small shift in cheek position can change the point of impact considerably. One day you're dialed in, the next day the gun goes nuts with the same pellets. The difference is how you lay your cheek on the stock. You really have to know your scope and how to manage parallax.
 
The barrel is such a huge factor here, makes it difficult to say. I generally only put tons of effort into guns if I believe in the barrel. I’ve heard some very good things about the F4 but I worry it’s same ole same with budget airguns... if you get a good one then your shooting straight, otherwise most are not so hot. 

How are you shooting mostly? Bench with bags? Standing? Sticks? Or a ton of different ways? Changing holds can effect accuracy. Just today I was shooting with a rear weight bias right in front of the trigger and wasn’t too satisfied. When I switched to resting it at the front it tightened up AND allowed me to see which direction my gun was recoiling better. That helped out a lot as I found the direction of recoil DIRECTLY correlated with where the pellet would hit relative to my point of aim. ... long winded way of saying hold matters.

Ill admit I have VERY limited experience with gas springs so I am unsure if you can find a way to reduce or increase the power to play with velocity as easy as you can with a coil spring. Otherwise I’d suggest playing with piston weight and whatnot. Maybe you could flip the gas ram around and see if anything changes. I think I did that on one of my NP2 trails.

This is an extreme step but perhaps you can experiment with spraying one of the various lube products (I’ve had great success with dollar store cleaning spray) onto a small batch of your cheap pellets to see if anything changes. If you do try this just be aware that eventually your entire barrel will become “lubed” from the pellets and the Accuracy will be yet again effected once the “lube” makes its way down the entire length of the barrel. If I was shooting competitively I’d use my pellets lubed and my barrel dry. That would require me to run dry patches all the time. I’m not sure if people actually do this but I’ve seen it work with my own eyes when I tried. I didn’t measure the lubed pellet velocity change (or at least I didn’t record it) but it absolutely tightened groups for the 2 (I think it was 2) types of pellets I tried. ... I have a lot of CP box pellets so I always TRY to get them shooting good. 
 
Spray a little PLEDGE on them and let them dry then try Shoot again. Seat them in the barrel with a fat headphone jack same all the time. Shoot like this enough you may get better groups. Practice practice practice.

Thanks for the replies. I am having a good time with my springers . I have to be doing something all the time and springers have kept me busy..

I have a Benjamem Rushmore that has Barrel droop. To I got an air rifle I have never heard of barrel droop. It shoots good groups with Hades and Barracuda s but it wants to shoot low. This has kept me busy for a while and cost me lots of money.

I bought a Gamo Whisper and it shoots very good. It even shoots the Crosman pellets pretty good. It loves the Gamo Red Fires. A 3/8 group at 27 yards. I nearly fell out

I bought the F4 at a flea market. I have tinkered with it a lot. Trigger job,cleaned it ,tried a couple of scopes and a couple different scope mounts. Not so much luck with it so far. I am haveing fun. Not bored

Thanks again and God Bless

It is funny that you mention the Gamo Whisper, my sister-in-law just had gotten my brother one for chipmunks and I went through it for him. It was shooting over 3" inch groups at 20 yards with just about everything. I then tried Crosman 7.9 gr hollow points and it grouped sub-dime sized groups since. Besides a good cleaning, the only thing that I had to do to it was to put a longer screw in the trigger to adjust out creep. Try different sized H&N pellets in the F4. H&N is one of the few companies that make the same pellet in different diameters. Find the one it likes and your golden.
