Troy PAR accuracy issues - UPDATE (post 33)

mmatt said:
I got my PAR from one of the first batches to hit Canada. Right from the get-go, I have had accuracy issues with it. I'm talking 3-4 moa or worse. Last I checked, I didn't buy an SKS. I sent it back and it returned a few days ago with a target that was supposedly shoot by a Troy employee showing 3 holes well inside an inch. The target was labeled "100 yards, 55 grain". No info was given on what the issue was or what work was done on the rifle if any.

I took it back to the range yesterday and nope. Nadda. I'm still getting sub-par (see what I did there?) accuracy with all types of ammo including different bullet weights, powder charges, brands, etc. No noticeable difference between them. I tried different optics, different shooters, and different muzzle devices. No difference.

I'm seriously disappointed. Anyone else have any accuracy issues? Did anyone have to use special ammo or loads?

Was it a Troy employee or someone from the distributor or dealer that sent you a shot up target?
I'd say that if you have tried various ammo, various optics and different shooters, whoever sent you the target is full of sh!t.
Shooting moa from a rest doesn't take much skill, so if the rifle isn't capable of it, then chock it up to lesson learned.

I've went through this stuff with Tavors and XCRs, and while it could be the individual rifles involved, it could very well point to the design.
 
Sell it with a disclosure that it shoots crappy. May be a good starting point for rebarreling to something else. Personally, I have a 5.56 version (shoots OK for the one and only time I took it out) and am considering a .300 blackout version when I can raise some more funds.

Hi mmatt.

Were not sure where you got the rifle from, however we are interested in helping you resolve the issue you are having with the rifle if we can. Please do not hesitate to contact us at sales@rampartcorp.com

Cheers
 
The accuracy does not equal my AR's and I relate that to my shooting and not the gun. The current PAR .30 HRT barrel was originally in an AR and was an easy -1" MOA but not in the Troy. That being said I attribute this less then ideal accuracy to how I have not yet adjusted to the ergonomics of a pump.

The sequence of events is far different to a gas gun by....Aim...Breath...pull the trigger......pump the action (which removes me from the site picture and eventually breaks concentration).....regain target.......breath and then the cycle repeats itself.

It would appear that I have improved on this shortcoming by the positive results from this weekend.
 
How crazy is the fluting in the chamber? Does it ruin brass? Trying to figure out whether to go 308 par or 223 par I don't like the sounds of chamber fluting :(
 
UPDATE:

I finally got the groups to settle down a bit. I shot one amazing 0.8 moa 5 shot group (at 100 yds) but that's not the norm. I'm mostly getting about 1.25 to 1.50 moa with some handloads. (55gr V-Max over 27gr Varget with a CCI primer in a Winchester case, 2.260" OAL using a Lee factory crimp)

I can live with that. I also tried some American Eagle 55gr FMJBT for giggles (I couldn't find any the first time I had the rifle) and it's printing around 1.75 moa. Again, not what I was hoping for but it's a heck of a lot better than the 6 moa I was getting before.

Why it finally decided to settle down, I have no idea. Some sort of extra long break/foul in ....? Either way, I'm at least content with the rifle now and will likely keep it.

On the subject of the fluted chamber, I definitely wouldn't re-use the brass. It's pretty extreme. (sorry, no pics. It's all buried in the snow at the range and I ain't diggin for it!)
 
So...whoever sent you the target wasn't full of it. Good to hear you sorted out the issues.
2moa is perfectly acceptable and a realistic expectation of a rifle in this category.

I wonder what it will do if you give the barrel a good scrub...

It's a brand new barrel... should I really have to do that?!? I will if there's a chance it'll help, I just didn't figure it'd be dirty from the factory. I thought you only needed to clean them to remove copper fouling after a few thousand rounds.

Well Matt it isn't a chrome lined barrel but rather it is a melonite barrel which should require a proper break in like any bolt action would. If you didn't do that the barrel is likely well embedded with brass fouling which means it will take a ton of work to clear up. I happen to have the chemicals to do just that much easier. Could get it done in just 2-3 hours. Come down to Fredericton and lets fix that up. I have saved many barrels badly fouled up.

If his barrel is grouping now and wasn't when it was new, clearing out all the fouling may have exactly the opposite effect. I would tend to suspect fouling if the accuracy gets worse as you shoot it, not better.

I remember a guy at club match several years ago. He was sighting in before the competiton, got everything dialed right in nice...then he cleaned the bore before shooting for score. Oppsie...results were other than awesome.
 
That's the whole point of the experiment.... it shoots good now after shooting it a bit, clean the heck out of it, if:

Scenario (1) it shoots just as good after a thorough scrub, then it has nothing to do with the barrel fouling helping it.

OR

Scenario (2) it shoots crappy again after a thorough scrub, possibly the barrel fouling helped it.
