Re: Ruger mini-14...why is it not accurate?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Grump</div><div class="ubbcode-body">Mid-1980s, my only real experience with one was a friend's stainless model with something similar to a Weaver K-4 on top.
First guy I ever knew who had rifle ammo in bulk in a .50-caliber ammo can.
It shot 1-1.3 MOA every time either one of us benched it, with those not so special 55-gr SP reloads. The stock fit tight enough and the trigger sucked. He tried to reduce it by drilling one spring hole deeper and broke the drill bit...but some after-hours time with the EDM machine there at BYU fixed that. He had GOOD friends.
Those were some fun times.
Anyway, the two more credible reasons I've heard for the more typical 3-5 MOA un-performance of the Mini-14 are occasional bore restriction from the clamp-on gas port/fixed piston, and an unfortunate barrel whip harmonic made worse by how light the barrel is in the first place. Bad combination.
Several over-priced remedies have been developed and sold to "fix" the Mini, but no one I personally know has ever tried one. Notably, one of the first Soldier of Fortune 3-gun matches was won by a guy shooting a *rebarreled* Mini-14. </div></div>
It's interesting that you bring up this story, because my dad has an old Mini-14 that shoots very similar to what you describe. I have little experience with Mini-14's besides my dad's, and 2 ranch rifles. The 2 ranch rifles I shot couldn't shoot worth a F*@#. I was trying to sight in a scope and thought something was wrong with my shooting, then I realized it was the rifle. I couldn't believe how inconsistent the rifle was, because I had always shot my father's Mini. Then one day I went to help another friend sight in his Mini-14 ranch rifle, and it shot similar to the other one, not worth a damn. I don't know the the serial number, but I know it's before they were making ranch rifles.
The trigger on the thing is heavy, and pretty rough. It's had an aftermarket flash hider on it since before I was born. One of those "screw on" flash hiders that is held in place by an allen screw. Dad said it helped quite a bit in how it shot, and he's never taken it off since then. I can bench the rifle and with handloads it'll shoot right at 1" or just over that for 3 shot groups at 100 yards. Occasionally it'll print something a bit smaller than 1", like around .75" or so. 2 of the bullets will sometimes be touching each other, and the other is thrown out a bit. Dad's is just an old mini with the single blade front site. But still, if I focus on the sights and how I pull that awful trigger, it'll always put up something around 1" groups (sometimes a little larger). Obviously it's not something that you would compare to an AR or a "precision" rifle, but it's something my dad has had since before I was born. Apparently dad got one that was a "shooter" or special, because EVERYBODY says I'm a liar. It happens so often, that I don't even bring it up most of the time. The only reason I mention it here is because apparently someone else has had a similar experience. Other than the flash hider, the rifle has never been modified, and to be honest, I'm afraid to touch anything on it because it shoots the way it does, and that's apparently VERY rare. If any are interested, I'll find out tomorrow the first 3 on the number.
