Tremor,
Those same dings on the aluminum Action Cover occurred around the ejection port on my rifle within the first 20 rounds. They were probably on my rifle before I even noticed them. I would attribute those marks on your rifle to factory test-firing, nothing more. God forbid, if you should actually get out and shoot your rifle, because I assure you that those scratches will get worse once you start pounding rounds down-range. Might as well get over it now, or return your rifle and move on with your life because you will never be satisfied...
All,
Gutinater and I conducted some "witnessed" accuracy testing of the M10X at the Genessee Range outside of Edmonton yesterday. Groups sizes were measured against 1" target squares using a 45x spotting scope from 100 yds. Micrometer measuring of group sizes and photos were both impractical due to the range being busy and pauses to check/change targets few and far between. To summarize our findings, with our test sample of 1 rifle, we found the following:
- Average group size with surplus ammo - 4"
- Average group size with commercial ammo - 3"
- Best group with commercial ammo - 2" with Federal Fusion 123 gr SP (but only when loaded and fired 1 round at a time from the magazine)
The test rifle frequently printed 4-round groups that were an inch smaller than the maximim, with a single flier opening the group up by the extra inch. No Fliers were discounted during our testing. Otherwise, we would have recorded many 3" groups with surplus and many 2" groups with commercial ammo. But those darned fliers opened up just about every group we fired!
I should note that the rifle's "practical accuracy" was excellent. This is in keeping with the smaller group sizes that we would have recorded were it not for the fliers. Off-hand shooting at steel gongs, it was a rare event to miss even the smallest 5" steel at 100m. I have noticed this phenomenon before, where a specific firearms design does not group particularly well, but tears up the range with accurate, off-hand shooting. In other words, perhaps not a terrific grouping "target rifle", but a perfectly fine "plinking rifle" suitable for an enjoyable day at the range. That is the M10X in a nutshell...
We should also note that the M10X appears to suffer from the same POI-shift as the Swissarms/SIG 550 rifles when using a bipod. The barrel is not free-floated, despite what the manufacturer says. As a result, when you "load" the forend on a bipod or a hard rest, you can expect the POI to displace upwards. Simple physics.
Reliability with the M10X was excellent, with a single stoppage occurring in well over 200 rounds fired. The stoppage was a double-feed attributable to the 5/20 P-mag that we were using.
As always, individual tastes, opinions and findings will vary. It is quite possible that the M10X will still group 2" at 100m with match ammo (if anybody can find some). However with commercial hunting ammo our findings suggest a 3 MOA rifle and with surplus fodder a 4 MOA shooter. In other words, slightly better than rack-grade AK accuracy, but not much better. A bit disappointing for a milled steel Receiver rifle, but not the end of my personal world. I bought the M10X to replace my AKMS as a cheap(er) 7.62x39mm plinking gun, not as a benchrest target rifle. In that regard I am still quite satisfied with the package as a whole. YMMV....
