was the gun, more often it was me.
Groups variation indicates it could be hold, trigger, or crown/lockup type of thing....you should NOT have any torquing. So if it were seal/powerplant, I would think your grouping would be verical strings, with little to no horizontal change.
Not talking down to ya, just making suggestions. It's easy to lose sight of what we know when we are frustrated.
--Check the crown with a cotton swab, make sure there are no bad burrs. You've been here before, so you have seen how to do the brass screw polish.
Also, push a couple pellets thru, with a verticle mark pushed into the back of the skirts with a knife, just a light reference mark. Insert your reference at 12oclock and see if there are any loose spots on the way down while pushing, or if it gets excessively loose at the end, and inspect the pellets afterward for any consistant marring/tearing of the skirts.
--Is your lockup good and solid?
--Breech seal in good shape?
--ALL screws down tight? I mean ALL. I have had screws on guns that would work loose under the stock, and caused movement. Don't THINK they should be tight, KNOW. ONlY way to know is to put a driver/allen on 'em and check. You were just inside of it, so recheck if you haven't.
--This gun have a front sight? If not, I'd get one on it somehow, or get rid of it...
. You can NEVER really check your scope function without irons, IMO. If it does, or you can fab one, take that glass off, and try to group with the irons. 10 yds is no indicator if you ask me, I use 15-20 open. If she groups when she's open, then you need to check the scope out.
Also, is it a low paralax setting scope?
--Trigger breaking clean? Like glass? If not, work on it, or replace it if there is an available insert.
--YOU......are you duplicating EVERYTHING the same. Same ritual before every shot? SAME hold...SAME grip on trigger....SAME resting position....SAME cheek weld....SAME number of deep breaths, then hold on the release and squeeze....no blinking....etc....
Not talking down, again. Just so happens, I think I've tried EVERYTHING, then I talk to Mike or somebody who is not too close to the situation, and they say "try this" ....so I think, Iknow this, I shoulda tried it.
I am still not convinced that gas rams are the way to go. I know that it takes about 4 hrs of my time to install a new spring/seal and lube tune....But it only take about 25 bucks including shipping. I am anxious to see what a gas ram replacement will cost.....should be ~100 bucks just for the part.
Good luck, and sorry it's not behaving. FWIW, I'da been happy with that RWS 94. GREAT gun. I think Cometa actually made it, but great gun.
