Cornpone,
Man did I open a can of worms,I sure did not mean to. I don't have anyone to talk about air guns but the good folks on the internet. I so did not want to start anything.
The rifle is my first pellet rifle. I bought it at a pawn shop. it looks like new. A Benjamen Rushmore. I was told that it was a higher end gun.
It is in .22. I don't have a choronagraph but it seems to shoot hard. I have tried all kinds of pellets and none seem to do well. If two pellets happen to get close together it is a pure accident. On good days I can keep them all on the target
I have a Hatsan 95 that shoots 1/2 inch groups at 30 yards. A Gamo Whisper that does the same. A cheap Ruger that I picked up at a flea market will shoot around an inch most any day. I have a Hatsan Flashpup that shoot less than a half inch with a wide of pellets, and a Stormrider that is a little more picky but it still shoots small groups everyday that I have tried it.
The Rushmore don't like any pellet that I have tried. I have tried several scopes.I have tried different ways to hold it. I always check my screws.
I keep trying to shoot it cause I really can't belive it can shoot that bad. It gets on my last nerve. I will not however post any thing about it in the future on this site.
Thanks for your support. I don't want to start anything so I will keep things to myself in the future
God Bless
Bobby
So for now I am a proud owner of a rifle the shoots patterns instead of groups
Bobby;
I am sorry we did that to your thread and I am sorry you were accused of something which was obviously never your intent. Sometimes people don't THINK, 'course I am not one of them, eh?
I had a Beeman RS2 that I just could not get to shoot as well as I wanted. I mean it was a functional rifle and it was fine for hunting squirrels and such. It just wasn't ever going to be a tack driver. Mind you if I had it tuned by someone who really understood what he was doing, it probably would have become such.
It sounds to me like you have that sort of a problem. I'd suggest the following, if you are still interested in tinkering with the rifle and don't want to spend money sending it off. Being a gas ram I'd probably handle it this way. Take the rifle out of the stock and check for fit. Even when the screws are tight if the rifle can move around in the stock it will never shoot groups. If it looks like it needs it, glass bed the rifle. There are folks here who can tell you how to do that but I'm thinking you probably already know. I got the RS2 to improve substantially by bedding the rifle in this tape:
TAPE I'm not going to tell you how hard it is to remove the rifle after that sets for a few months but you WILL need tools.

It immobilized the rifle in the stock that's for sure. There are probably better options. Also keep in mind that stocks change shape with humidity, you'll be wanting to make sure it is sealed real good.
I've had optics that failed but seemed to be all right. One day they would shoot groups all day long. The next day they were all over the place. I've made the mistake of pulling them off, setting them aside and putting another broken one on the rifle that I thought was good. If you think your optic is the problem, shoot it with irons on a calm day off a bean bag or make darn sure the optic you put on to compare is actually good.
All the pellet sorting and weighing in the world won't mean squat till your rifle is shooting reasonable groups, just find the one it "likes" best out of the pellets you have and start working on the rifle. Don't change pellets until you see improvement. Then you will know the improvement was on the rifle and not this or that pellet.
Lap the barrel. Now with AGs that process isn't nearly as hard to do as with a PB. You don't need to cast a slug in the barrel. Just get yourself some JB bore paste and some cleaning pellets or really tight fitting patches and polish up that barrel till she shines real good. Don't over do it. Then one drop of moly or silicone grease and start shooting. Make sure you start the process with a few ten shot groups so that you can check the work with a few more after it is done.
Check the crown. If it's rough or uneven read up on recrowning the rifle and get yourself a small FINE stone ball to do the job. It's not that hard to do a simple crown.
All this talk about "artillery hold" is short hand for "consistency" anyone who has been shooting the darn things for half a century will tell you that. The reason for the light hold is the amount of moving parts in a springer makes said consistency harder to achieve than with a PB. The soft hold can get you bit by your PB rifles so keep that habit in mind when you switch back. The easy solution when working on getting one to shoot is a bean bag or a sand bag. They give enough that it is easy to get the same recoil pattern every shot with minimal stock contact.
I hope you have good luck with your rifle but if you decide to sell it and you want to be honest simply shoot a target with three or four five shot groups on it and attach a photo of that to the advert. Then you can not be accused of misinforming anyone about anything.
