First shots with my XCR-M... Smooth operator...

After 400 rounds, i am confident that this rifle with the right load will be an easy MOA, everything is predictible and regular shooting this rifle, this stability will permit nice precision and maybe even better, load devellopment will start after i am back from overseas, end of May... JP.
 
Just for everyone's information this came from a discussion I had with Wolverine Supplies in another thread.


Mr Wolverine said:
Do not set the gas setting to maximum to start with, that is very bad advice. Set the gas setting to the smallest that the rifle will operate on. On the maximum setting you are simple "hammering" the rifle unnecessarly. This would be like taking a new vehicle and running the rev counter into the red all the time. When running in a new rifle (any new rifle) treat her gently, nurse her, keep her clean and well lubed. When she is run in and all the working parts are honed to a fine finish, then and not until then, you can up the anti if you have to. Keep the larger gas settings for use under adverse conditions, or when you want to have an excess of power to insure reliable operation, like a competition.

Make sure your barrel retaining bolt stays tight. Do not use red Locktite on it. Torque should be 250 inch pounds, that is very tight for the small bolt. Not 250 ft lbs that is lots for a cylinder head on a diesel engine.

Yes, I have discussed this point with Alex and he agrees with me, the manuals should be updated, but that is not a high priority due to the demand for rifles.

I notice on the LMT target you used A-Max bullets (which I generally find to be very accurate). Did you also use A-Max 168s on the XCR targets?

No not a-max, but did try their match 168. No joy.
The lmt ss 20" barrel loves 168 amax's, and the cl 16" loves 155 scenars. Sure wish it were the other way around !
If someone can show me four groups, on the same paper, of 1 moa at 100 yards out of the xcr-m , I'll go buy another one immediately.

Heading out Monday to shoot my XCR-M.

For ammo I will be using Federal Gold Match 168 grn Sierra MatchKing, usual American Eagle 155 grn FMJ cheap stuff, Hornady SST 165 grn and if I have time Berger VLD 168 grn hand loaded stuff I will try and do tomorrow.

Post my results after shooting.

Curious on the AE "cheap stuff" results and I'm holding you to it ;) Reason? If you can get the AE to group reasonably well then caramel might really be on to something :cool: Yeah I know it's a battle rifle but still, very interested :D
 
OK, so yesterday I pick up this

XCR-M.jpg



First thing I do is clean, and lubricate the rifle. I couldn't remove the barrel because I didn't have my allen key set.
Anywho, I'm a happy camper nonetheless.

After reading these forums, and seeing where a vendor has written "Do not use the firearm on adverse while breaking it in.... it's like revving a new car to red line.... they haven't updated the book yet, too busy building the rifles to update."

So I crank down the gas setting as advised from the forum. Load up the first mag, aim - BANG, click, re-####, bang, click, re-####. You get the idea, a real expensive semi-auto single shot.

Crank up the gas regulator to just under the + setting. Cycles all five rounds. Load up again, fires 3 rounds, hard stoppage. Cartridge damaged. Remove the mag, and the follower is stuck down about 1/4 inch which allowed the cartridges to move freely within the magazine. So I oiled the contact points of the follower in the magazine, reloaded and continued. No problems with magazine after oiling.

I gradually turned down the gas regulator one notch at a time until I have a failure to feed, then turn it back up one. No issues with subsequent rounds down range.
Fired 60 rounds in total, American Eagle 150gr, FMJ boat tails. Not going for accuracy, just wanted lead down range. Once I decide what optics I want, and outfit the rifle I will try for accuracy.

Scary first two shots with the rifle. If I had followed what is written in the manual, vs the forum, I wouldn't have had such a scare. All is well that ends well though, and I'm still smiling.

Thanks for the post springtown. But IMHO, if there is blame to be apportioned, it rests in your first sentence and not the board. I gotta' say when I read that the other day it pissed me off. Right, "We at BMW are so busy building such fine motor cars that we don't have the time to tell you there is no oil in the engine". Yes I am exaggerating but sheeesh :rolleyes: BTW, I'm allowed to be pissed not only because that is a pathetic response from RA but also because I have one on order so it makes me wonder....

I may as well ask because someone else will: what mags were you using? Glad it ended up working out ok for you though :D

Pretty insulting when someone blames a minor malfunction on other people in the forum. Wolverine supplies advised that the setting should not be at maximum. They are the distributor for this rifle in Canada and therefore responsible for any warranty work etc etc. So if they share updated info I can only assume such a reputable dealer is correct.

Personally I think if your going to hop into a thread and insult a group of people who are simply just trying to collaboratively share experiences then perhaps you should just move along.

Wolverine is a good dealer and that is why I did follow their advice. There would be no reason for them to spread false information, so I took their word, and the rifle failed to cycle. It freaked me out initially. But I still took their advice and found a compromise where the rifle will cycle properly, that isn't on +, so it will be easier on the rifle during the "breaking in" period. I wasn't trying to say they were lying or anything like that.
Maybe next time I'm out with her, I'll be able to turn it down a bit. Just have to find the setting that works. The mag not feeding right erked me more than having to turn the gas up. But a touch of oil fixed that.
Like I said before. Still smiling about the rifle. Once some PMAGS come available again, I'll be all the more happier.
 
Actually that is very good (only based on what I have been reading here); it sounds like a major weak spot of the 308/M is the original mag. Perhaps take the wolverine advice into consideration if you go to a pmag (for example).

I'm a big fan so forgive me as I watch the growing pains of the M. Interesting I was asking about them at Cabelas Emonton and buddy said he had not heard of any returns or complaints from their "m" buyers.

My factory supplied ASC mag was crap. PMAG's seem to have solved my issues at this point.

60 rounds down the pipe of mine with gas setting set at max as per the manual. Going to lower it to 3 to start on Monday and see how she operates.

Thankfully I chose to "invest" my kids education fund in PMAG's ;)
 
The original mag is sh1te, get pmags and move your rear sight to the rear where it should be.

Have a look at the robarms website h t t p://xcr.robarm.com/xcrm.php
