Ruger Mini-30 Accuracy Range Report

Mini 30.jpgHey guys. I've seen several threads about the Ruger Mini-30 accuracy so I did some testing this afternoon. I fired 5 shot groups at 150 yds with a Weaver 3-10 by 40mm set on 10 power. I shot in a prone position with the forend resting on my range bag. I used a variety of steel cased and brass cased ammo. Here are my results.

Steel Cased
Golden Tiger 124 gr FMJ= 6.4"
Silver Bear 122 gr Hollow Point= 2.5" I thought that was a fluke so I did another one.
2nd Silver Bear 122 gr Hollow Point= 4.75"
Brown Bear 125 gr Soft Point= 6.5"
Hornady 123 gr VMAX= 7"

Brass Cased
Fiochii 124 gr FMJ= 5"
Federal American Eagle 124 gr FMJ= 5.5"
Federal Power Shok Soft Point= 6.25"
MFS 124 gr FMJ= 5.5"

I would call my Mini a solid 3 to 4 inch shooter at 100 yds. It's not great, but have to keep in mind the Mini is a semi auto carbine using cheap ammo. I thought there would be a greater spread b/w the different ammo types.

I used a Ruger 20 rd factory mag in this test and had problems with the mag feeding the last rd part of the time. That was frustating. I've had the mag less than a year and it's always worked before.

Well I thought everyone would appreciate the info.

Nice to know. Would like to see a test with some higher grade match ammo to see what happens.

Typical mini accuracy.

There are some modifications that can be performed to improve accuracy:
  • Uniformly gap the gas block
  • Replace the gas bushing with a smaller port
  • Add buffers for the slide
  • Add an Accu-Strut/Mo Rod

The upgrades mentioned by Dnprk and I would add a trigger job, it really helps alot. Other than the silver bear which is a suprise, the brass cased ammo performed better. If your rifle is stock, I think there is plenty of accuracy you can wring out of it. Still nice shootin...

"...with the forend resting..." Move the rest back to in front of the mag. Not that it'll help much.
"...3 to 4 inch shooter at 100 yds..." Ludicrous for the money demanded. You shouldn't have to do anything to a rifle with a thousand dollar price tag.

The new Tactical is supposed to do much better than that.

DnPRK and Bamashooter: thanks for the tips. Has any of your guy's mods caused reliability problems. e.g. using a smaller gas port?

I have a recoil buffer on the gas tube(wilson 1911) and one on the op rod. My rifle shoots my handloads and brass cased ammo great. Never had a jam, but it will not shoot the wolf or tula ammo. I could take the buffer off the gas block and it would work fine with the steel cased ammo. I like it with the recoil buffers on so I will just stay away from russian ammo.

A number of years ago, I was looking for a stainless Mini 30. Every one I looked at had lathe marks on the barrel behind the front sight. I must have spent a few months and looked at at least 100 rifles before I found one that had a perfectly smooth barrel. No lathe marks. I bought it!
To this day it shoots one inch groups at 100 yards consistently. I called Ruger about this and spoke to one of the engineers. He told me that I got lucky and found one that was machined to near perfect specks.
He tried to explain what that meant but I was lost. I did not comprehend the technical terms and what they meant. In closing, he just said to consider myself one of the lucky ones. That was the end of the conversation. Anyway, even with the Wolf 154 grain ammo which I don't use but just wanted to see what it would, I was still keeping my groups under 2 inches. With Corbon 150 grain, I am spot on!
My scope is a 3x9x40. I almost sold it a year ago to a guy who wanted it real bad, but this Mini 30 is a keeper. It will be passed down to my son.

Typical.

I have a Mini-14 Ranch Rifle .223 stainless. Purchased in 2010.

I installed an accurizing rod to the barrel also.

my BEST 100yd is 3.5". Typical group is 4"-5.5"

sad sad sad

it sure is a fun gun to shoot though. 100% reliability. The thing is built like a freaking tank.

take note

Note that the groups were fired at a reported 150 yds, not 100. Since its fairly typical to analyze groups shot at 100, don't critique these 150 yard groups to heavily. All would be smaller at 100, obviously.

Missing from the ammo types is WW FMJ, which shoots best in my 189 series Mini. Also, I've not done it yet, but have a handful of Lapua FMJ which I will shoot for group in the near future. Too, a handload worked up with the Sierra 135 Match King could be quite interesting, but pricey.

All said, I don't expect more from a Mini-30 than what most reports indicate, so not disappointed.

Thank you bamaranger for pointing that out. I probably should have shot the groups at 100 yds since most tests do that. From my results at 150 yds I estimate 5 shot groups would be in the 3 to 4 inch range at 100. Still I would call my Mini 30 a good 150 yd deer or coyote gun.

i had a mini 14 and it shot 1" to 1.5" all day long at 100 yards but the 30s is a heaver bullet and i have never shot one yet so i would asume that its group would be a little bigger but i dont know
