Thank you, Gentlemen. I will try the Accustrut first as it seems to be the simplest way to go. My friend recently bought a Stainless Ranch Rifle which we sighted in with a Bushnell 3-9 scope. Absolutely no problems except he kept adjusting the knobs. My old Mini will group just fine when the barrel is cold. Shoot one shot, lay the gun down, smoke a Kool and fire another one. I have accumulated scads of assorted .556/.223 ammo which is what I play with.
My other question is regarding the difference between .223 Remington and .556 military ammo. Somewhere I read (long ago) that there is a difference between the two. My last AR has a .223 Wylde barrel (don't recall the twist). What gives with this ?
again, try your questions as a polite and thoughtful person,...and I have no problems doing my best (I admit I am no expert) to try and help you. FIRST...information on your part is helpful.
1) when you were unable to zero your rifle, and you shot shotgun patterns at 50 yards...did you try and contact ruger regarding your issues? what did they tell you?
2) due to the design, the mini is known for recoil that will shake loose both the open sights and scope rings. one time my groups were all over the place (as bad as yours) and I noticed one of my rings shook completely loose. I thought my optic was effed, I just overlooked something simple. were you using an optic or irons? have you tested both optics and irons for accuracy? were all locked down completely? Loctite is your friend.
3) what ammo did you test? tula, wolf, or premium match/hand loads? hate to be obvious, but even the factory ammo I have tested has as much as a 2" difference at 100 yards. the mini is ammo finicky, more so than some other rifles, most admit it. what brands? what bullet weights? are you trying to match bullet weight to twist and running various premium ammo to get the best results? if not, what hand loading data can you provide?
4) how many magazines did you test during your shooting? what type?
5) have you inspected the front sight for potential canting in the manufacturing? the inability to zero is more likely something to do with sights or optics the vast majority of the time.
6) your inability to zero the rifle has often been fixed by properly torqueing and evening the gas block. have you inspected the gas block? does it appear to be uneven or "wrong."
many feel that if it was put on sloppily at the factory, this will help improve several issues with zero and accuracy. my first mini's gas block was WACKED. just even it up and torque it properly.
7) when you added your strut, did you notice any improvement in groups at all?
8) what stock do you have? have you changed it at all? the factory stock is known to be a sloppy fit. as you know, a stock change can and will improve or worsen accuracy. mini shooters have gotten awesome results by bedding their factory stock (a common practice for accuracy improvement in many rifles). when I went to a wood stock, it locked up so tight, I passed on bedding the stock.
top 3 most effective accuracy mods among most mini owners: quality ammo or hand loads, bedded stock, strut (mostly for thin barrels), change of bushing (this is more for settling it down than accuracy imo), torque and even gas block.
feel free to respond. as I said, I am no expert or gun smith. if you have considered all the possibilities here that might be obvious to most relatively experienced shooters....then my personal diagnosis is YOUR MINI IS A LEMON. IT HAPPENS. no way it should shoot this bad out of the box, much less modified in any way. TALK TO RUGER.
every firearm company has made has its share of lemons. go to you tube and watch exploding AR's and malfunctioning guns of every type, including mini 14s.
sucks you got one.
I have personally sent 2 brand new firearms back to factory for malfunctions/defects (neither a mini), and was very happy to find they were DEFECTIVE and were easily repaired.
good luck. if you have nothing further to add other than the glories of other rifles compared to your defective mini, then please seek help elsewhere. my advice again, is a technician at RUGER will be happy to talk to you..
I haven’t shot it in this configuration, yet.good looking mini! if you shoot that well off hand, your mini is a shooter and so are YOU!
With you, there, Hawk. Just picked up a Henry big boy in .41 mag. Man, what a shooter. I have no qualms taking it hog hunting. Great companion for the OM Blackhawk.don't forget levers! super easy to maintain! I find myself spending more time with them for the reasons you said....so easy to clean and maintain.
good question. I couldn't answer that with any certainty, but I would say from just reading casually, more seem to be satisfied overall with the gb's as opposed to the standard pre 580 minis.could it be that the gb802's were mostly destine for govt use, that gave them more attn. to detail? mine was fine. or was it hit or miss across the board on all mini's?
fyi... back in 1980ish, the gun dealer wasn't going to sell me one but when I showed him my military i.d., he sold it to me since I was govt employee.
as a 185 series your mini is definitely not a tapered barrel.-How do you know which generation Mini one has. Mine is in SS and the barrel appears to be tapered, that is, thee is what can best best be described as a "ring" about midway down the barrel. It's very difficult to discern but it appears to be a taper point, or rather the barrel diameter is a bit smaller at that point. The serial number on mine is 185-68xxx.
