Miseryguts Posted February 9, 2017 Report Share Posted February 9, 2017 Hi, apologies if this has been discussed before, but a topic search did not bring anything up...... Just had a new M&P 15-22, and am disappointed with the accuracy. Just want to know if I am expecting too much from it. At 50m I am seeing 2 inch variation in shots, that is 4+ MOA, this from bipod on a bench with a middle of the road 8-32x50scope and an after market 3lb trigger. I find this very disappointing as I wanted this rifle for rabbits at 50 to 75m as well as fun stuff on gongs. Tried Semiauto, subsonic. Standard velocity and Hi velocity ammo. It is fitted with a suppressor. Any comments welcome!! Link to comment Share on other sites More sharing options...
MrCetrizine Posted February 9, 2017 Report Share Posted February 9, 2017 The suppressor won't help but semi auto blowback rimfires can never be track drivers due to the variable nature of their action. Mine using Federal American Eagle High velocity shoots about an inch group at 25m, which is as far as I shoot it in practical comps. Link to comment Share on other sites More sharing options...
bradders Posted February 9, 2017 Report Share Posted February 9, 2017 It's a plinky plonky plastic .22 with a loose sporting chamber and some parts made from Monkey Metal They're good for what they are I've heard that a company called Bradley Arms makes rather spiffy ones Link to comment Share on other sites More sharing options...

Well, my BAR .22 will put all rounds through one hole rested at 25 yards - so the CAN be accurate....... Link to comment Share on other sites More sharing options...
The_Dogge Posted February 9, 2017 Report Share Posted February 9, 2017 I would think 1" at 50yd would be a reasonable expectation, if it didn't do that I'd be disappointed. Have you ejected a live round and if so does it take a chunk out of the bullets on the way in? Check the usual suspects, is everything tight? have you tried with a different scope? different shooter? without the mod? off bags instead of the bipod? What does the crown look like? "1in9" on here has one, I recall he said he wasn't impressed with the accuracy, but conceded that he hadn't tested it with a scope which would allow for a really meaningful test, as he mostly used it for mini rifle. I don't have one, but I have a "Colt" (Umarex) equivalent which is largely monkey metal, even the barrel is a thin steel liner with an alloy tube around it, it shoots "one hole at 20yd", i.e. about 2MoA, 1" at 50yd, so just being made of cheap metal doesn't make reasonable accuracy impossible.

Hi, same off bags, Scope is a Hawke Sidewinder 8-32x56 with parallax adjustment, and let even me shoot 1MOA groups at 75 yards on a 17HMR. Crown has not been dished, haven't tried without mod, nor ejected a live round. Will try both in next couple of days Yes, I would be happy with 1 inch at 50 yards(2MOA) as at 75 -100 that would mean I can be fairly sure of hitting Peter Rabbit Link to comment Share on other sites More sharing options...

1066 Posted February 9, 2017 Report Share Posted February 9, 2017 Sorry chaps, absolutely nothing to do with M&P 15/22's but here's a one hole, 25 yard, 5 shot group I shot on Saturday at out local pay-as-you-go range with my rabbit rifle. A live round won't fall into the hole and the rim covers all the shots. Link to comment Share on other sites More sharing options...

1066 Posted February 9, 2017 Report Share Posted February 9, 2017 What rifle? Is it Semi? No, although I do have an old Voere that I've had for 40 years that shoots very well for a cheap clunker. This was shot with my Sako Finnnfire, Lilja barrel and homemade tuner. Link to comment Share on other sites More sharing options...
MrCetrizine Posted February 9, 2017 Report Share Posted February 9, 2017 That, I have no problem believing. My own match grade Feinwerkbau bolt action is capable of sub calibre groups at 50m (even if its owner isn't). It's semis and more specifically blowback rimfires that I believe can never be sub calibre accurate (though I'm always happy to be proved wrong with evidence). I believe this, due to the variable nature of an action that is at least beginning to open enough to produce a non consistent drop in pressure before the bullet has left the barrel. I'm aware that good engineering and quality parts can minimise the problems but I still believe the are too many variables at play for blowback rimfires to be consistently highly accurate. This is an interesting article and test on making semi autos accurate. Not bad results with a lot of work but certainly not through the same hole, unless it's a big hole... http://gundigest.com/how-to/research_ruger10-22 Link to comment Share on other sites More sharing options...
Zzrpilot Posted February 10, 2017 Report Share Posted February 10, 2017 They are not target rifles by any means and best used for practical shooting and plinking. the performance centre one is better and groups well at 25 and 50m witth cci AR tactical Link to comment Share on other sites More sharing options...

Miseryguts - I'd get someone else to shoot it, just to see if you need to improve your technique Link to comment Share on other sites More sharing options...
1066 Posted February 10, 2017 Report Share Posted February 10, 2017 Wow, that's an amazing group, did you find the tuner made a lot of difference? Yes, tuner definitely makes a difference, however this is "work in progress" and I feel there's more come if I can find the time tinker. Link to comment Share on other sites More sharing options...

If I shot a couple of groups like that I'd stop tinkering immediately! Link to comment Share on other sites More sharing options...

I would too if they were all like that.... What I'm really interested in is longer range accuracy with the .22lr If I shoot a .5 moa at 100 with my 6br I'm mildly disappointed, If I shoot a .5moa with my .22 I'm over the moon. I think as we search for ever more accuracy tuners will be seem more and more, even on sporting rifles. Link to comment Share on other sites More sharing options...
Miseryguts Posted February 10, 2017 Author Report Share Posted February 10, 2017 Hi, tried cycling some rounds through the action today, As a round is loaded, the rim leaves a 1mm wide track across the lands of the next round. I figure not much can be done about that? MrCetirizine Thanks for the link, a very interesting article, but unfortunately I have spent enough on this pile of ****!! Lots of other stuff to try at the range, thanks for all the comments and opinions Link to comment Share on other sites More sharing options...

T I'd seriously doubt you'd get better out of a semi, barring the occasional fluke group. It does show that performance can be improved with good build and parts but I still maintain that a blowback semi will never the kind of accurate you can get from the most pedestrian of bolt actions. For a semi auto to perform as well as a bolt action, I think you need consistent ammo which is tricky in rimfire due to the primer, a locked bolt and a well regulated gas system. I've seen semi autos be sub calibre accurate but never a blowback. Link to comment Share on other sites More sharing options...

When firing, the action moves so fast that there is much less dragging.Fire one round then drop the magazine and inspect the top round, it will barely be marked. Plus it's typically just marking the wax/grease which will be melted anyway. Link to comment Share on other sites More sharing options...

Right on! just checked some FTF,s and they are hardly thru the gunk on the round Link to comment Share on other sites More sharing options...
Miseryguts Posted February 13, 2017 Author Report Share Posted February 13, 2017 Hi, thanks for all the advice on this topic. Had a day on the range today trying different ammunition, following advice took suppressor off, took bipod off, supported gun on bag under action by magazine. Wind 5 - 10mph at 10o'clock Best 10 shot group at 50m was 1 inch by 1/2 inch with a well known brand of semi auto ammo. Happy with that, that's 2MOA Thanks again Not as miserable a miseryguts as before! Link to comment Share on other sites More sharing options...
