Ruger Mini 14 accuracy and bolt

#1
Hi everyone, I have a straight pull ruger mini 14 in 5.56 and im just wondering what is the best accuracy i can expect from this rifle. I've managed to hit a figure 12 from 600ydswith iron sights using mil surplus ammo but im thinking of getting a scope to stick on it, however what accuracy can I expect from it?

also i have 2 problems with the bolt, when i fire it moves back maybe half an inch then back in place is this an issue? just wondering if with a weaker sping it might become "accidently" semi auto haha although it wouldnt be worth it as the range master can kick on full auto

also when I was using wolf ammo the bolt was fine (but still moved) however when I changed to surplus It began to stick and refuse to slide back, I had to yank on it up to 15 times for it to move back, however it would do it first time other times

is this due to steel case ammo not expanding as much as brass?

any help would be appreciated

For use with 5.56Nato (SS109 62grain) You will need a 1:9 or faster twist. The older military 55r bullet is ok in 1:12

If it's coming unlatched on firing there's something wrong. Get it checked out.

yeah the twist in the barrel is good but what moa can i expect?

what could be causing it to unlatch?

Is it something like this one?


This one belongs to my mate's wife. She let me shoot it for a while. :)

Wear, broken parts, over pressure cartridge.... ?

No, that's not a Mini 14...

Many straight-pulls will unlock under the inertia of the working parts (L98 included). It shouldn't be a huge issue, but a stronger spring is all you can do.

Accuracy-wise, if you're getting 4MOA you're doing bloody well. Expect MUCH worse, unless it's a heavy-bbl version. You can buy a stabiliser (or could in the past) which supposedly helped.

Wolf 55gn is very lightly loaded, and yes the steel will spring back more than brass. Handloading is the way forward, but the rifle will prefer some brands of brass more than others. Keep it clean and don't load it too hot.

Could've fooled me Stoaty. I got told It's a Ruger mini-14 Police carbine.
All ok with you and family? Long time no see mate!

its clean and well oiled, but do you know what might be causing the second bolt problem? also my wolf is 62grn not 55

as for 4moa, i managed to hit a figure 12 twice with 20 rounds rapid fire at 600 yds while aiming high with the sights, personally i think that when It has a scope 4moa will be a thing of the past.

what causes it to have such accuracy problems?

Cheap rifle made to a price then bastardised to suit UK laws. If the bolt comes unlatched every other round what do you think that does for consistency?

It's never going to be great.

Ruger Mini-14



Looks like the kid brother of the M-14 Service Rifle

A very light, whippy barrel, and tolerances to ensure functioning (i.e. loose).

The hand fitted heavy barrel match versions will do around minute of angle.

With the standard ones,v 4MOA is the absolute best you can possibly expect, and it doesn't matter what you put on top of it. 6-8 MOA with one is nothing to be ashamed of if you have an iffy one. They're not intended as target guns -- they are simply the world's most expensive plinker, intended to do "minute of tin can", or "minute of feral pig".

I carry a sports bottle with me and pour it on the barrel to cool it down, 60 rounds makes it heat up very fast, a couple times i have put a 150+ rounds through it and the oil starts to burn, still makes for a bit of fun as its a great rifle

not something id buy if i had the chance to go back but still a bit of fun all the same

what is it that makes the mini 14 so inherently innaccurate? other weapons with the same barrel length and calibre do far better, mine is one of the older ones that originally came over, still im happy with it

As I said before, a very (in fact extremely) light, whippy barrel, and tolerances to ensure functioning (i.e. loose). This is also compounded by a very dubious bedding system with the metal held into the wood or plastic essentially under spring tension, and the relatively loose fit between the metal and the stock does not ensure that they are in exactly the same relationship every shot, which compounds the problem of the light whippy barrel since it affects the consistency of the barrel harmonics.

As the meerkat says, simples!

now i just feel stupid for buying the damn thing in the first place :( , maybe its a bit of kit to deactivate or stick on guntrader and hope someone else buys it

still with a few hundred rounds of ammo left for it there's only one thing to do and thats burn through it all and torture the gun to death haha

I think il keep it and use it as a spray and pray gun

Ive had a Mini 14 ranch rifle for over twenty years and never had any problems with it as long as I dont fire off hundreds of rounds with a half tidy scope and Choete furniture it does the biz for me, for any longer range I use my Parker Hale 1200 7.62 also over twenty years old, they aint broke so why get rid

Over twenty years? Over twenty years ago (Pre 1988) you could have had a semi-auto one. Did yours slip through the net?

The Ruger mini 14 isnt an accurate rifle end of. The latest incarnation has various tweaks such as a muzzle brake (tuneable) and a thumbhole stock but its minute of deer accurate i.e 4" at 100 yards. I have used a straight pull model and its ok at 2-300 yards but dont expect miracles as its usually a 1 in 12 twist. Federal American Eagle red box ammo is ok for this but the bullet drop at 300 yards is about a foot!

Sorry, I know I'm a year late to this party but here's my £0.02.

The mini-14 is a good rifle but will never be as accurate as a bolt gun or AR, generally speaking, and the price reflects that. There are many problems in the BAO version and it is generally considered a tool for relatively short range work (or if you're in the A-Team and don't want to actually kill anyone). I have seen them do very well at the McQueens competition (fig14 snaps at 300yds) but much beyond that and you're lucky if you have a consistent one.

With the reports of the bolt moving back, do you mean the bolt handle? The bolt itself should never unlock as you fire - this is a recipe for disaster, get it looked at now if you haven't already. The L98's (GP) bolt should never move either but the charging handle moved all the time.

With stiff extractions the straight-pull design doesn't allow for the primary extraction that you get with a bolt gun or would happen if the rifle was semi-auto. Using RG or other surplus SS109 can give rise to it as the design of the SS109 is slightly different to the .223rem commercial ammo the rifle is most likely chambered for. By reloading ammo the problem can be eased or stopped and a chamber polish/ream can often help as well. I've made many barrels for straight-pull rifles using the same chamber reamer and headspace dimensions and no two are exactly the same, some will function with any ammo, some will be a bit temperamental with surplus and one or two will regularly stick especially after some rapid strings.

Hope this helps.

My Mini 14 can get 2.5" at 100 mtrs on a good day using Sierrra HPBTs, but at 300 mtrs I would have problems hitting a barn. It's a cheap and cheerfull gun, digests just about anything I feed it with. If they are still available, Kart make a 22 conversion which with the wrong ammo goes full auto! Found out the hard way when 5 shots dissappeared in one go. The queue behind me to have a go was impressive.
As has already been mentioned with such a thin barrel no great accuracy can be expected and heat build up can be impressive.
