Help with new Ruger sr1911

[coleman79]

Im really curious to know what shape others bores are in. I just bought my new Ruger 10mm 3 days ago it functions perfect shoots pretty good I'm getting around 3" groups at 50yrds so far with my reloads. But with all that the bore looks like its had 60grit sand paper drug thru it its almost like machining marks down the grooves. Ive never seen anything like it but it doesnt seem to foul at least no more than usual. Im kinda use to all my CZ bores there literally mirrors and shoot like they look. I would certainly feel better if my Ruger looked that nice. So how do your guys look, like mine or are they polished nice?. Appreciate any and all replies.

Mine shoots well, also. I noticed that the grooves seem to have a raised ridge, like a tiny off-centered land in each of them. I would not describe it like machine marks, but certainly not polished.  Definitely different than any others I've seen.  This observation was just with a light, not boroscope.

Ruger is known for not having the smoothest bores out there.  But they generally shoot fine, and 3" at 50 yards is excellent accuracy from a $700 gun.  Most would call that acceptable 25 yard accuracy.

Thanks for those replies fellow's just wanted the peace of mind that it wasnt possibility a lemon barrel. I agree of course it is acceptable accuracy the bore just had me second guessing. Ive never owned any ruger centerfire handguns lomg enough to really check out the bore close. Again thanks for the replies.

Wow 3" at 50 yards is amazing.  That is the Les Baer standard from a ransom.  If that is consistent across as the range, ruger has a winner.

I thought Les baer was 1.5" at 50 I may be wrong. But mine will certainly do it benched of course and if I do my part. Ive shot 3 seperate 3 shot groups at 50 that measure at the 3" mark. I normally shoot 5 shot groups but i was trying to conserve ammo the other day. By far the most accurate powder in it is AA#9 with 180gr xtp. It will rag pretty little 1.5" groups at 25yrds all day. The barrel doesnt look like it would from looking at the bore but it will, must be very consistent bore is all i know. The slide to frame fit has zero play along with the barrel lock up. I took it to 100yrds and kept it within 8" with 3shots.

for Les Baer, 3" is standard (2.5" for the 10mm hunter), 1.5" is an optional upgrade.

I just bought one recently and found the same thing with my bore. It shoots fine and has good accuracy but the bore looks similar to your description. It's the roughest bore I've seen in a new gun. Seems to have longitudinal scratches running with the lands and grooves. It looks like maybe the boring bar had a rough cutter on it. All of the lands and grooves seemed to have them. I have had other Rugers and they usually have pretty descent bores. As good as it shoots I doubt they would replace it if I send it back.
