Took the 581 Stainless 5.56 to the range today.

Well, mixed results....

My Ruger 10 round mag was a bust. Continuously jammed using the 10 rounder. This was the first time I used it. Got it on eBay without package. Switched to a Ruger factory 20 and it fed perfect for about 150 rounds....

Next, it did not like my 77 grain handloads. Not consistent at all. While some 1/9 will like it, this one didn't 4-5 MOA at best. Even tried my 2.5x Bushnell. Best was about 1" to 1.5" at 25 yards when sighting in. I'll have to try some MK 262 MOD 1 factory next time.

Federal Lake City M193 - AWESOME! One ragged hole at 25 yards with both the 2.5x Bushnell, and almost as good when I battle sighted with iron sights. I annihilated clay pigeons on the berm at 75 and 100 yards with iron sights. Even annihilated pieces of clay pigeons on the 100 yard berm.

I guess I will stick with the 55 grain 5.56 for for now.... Good thing I have a lot of it. 1,000 rounds of factory and about 500-600 of 55 grain FMFBT reloads with IMR 4064.

L C brass is my favorite for reloading once it is all prepped.

Too bad you sold the 1:7 twist barreled mini. They don't come along everyday. But yes, the 181+ series mini with the 1:10 twist barrels and the more modern 1:9 twist barrel mini 14's are famous for shooting M193 very well.
Also ridiculous now that 5.56/ .223 ammo sells for 50c or more per round. I'm getting happier by the day that i took your advice and picked up a 5804 mini 30 ( and also a 5803).

Are you sure it was the mag?

Maybe a stronger wolf spring will solve the problem.

I have a 10 round Ruger mag that is giving me problems. I want to put a new spring in it.

Yep. Started with the 10 rounder, and jammed 4 out of 5 shots no matter what ammo. Prior shooting outings, I had used Ruger factory 20s and 30s, and Tapco 30s for 300-400 rounds with zero malfunctions, with a wide mix of ammo. As soon as I tried the 10 rounder for the first time, it was a serious problem. Switched to a Ruger factory 20 (and a 30) and again had zero malfunctions.

With the 10 round Ruger mag I replaced the factory spring with an ar15 spring cut to one more turn. The extra turn makes up for the goose neck at the top of the factory spring which I believe is the problem. The follower is now supported in the front much like the Ruger 5 round mag.

Try one. It fixed all four of my 10 round mags.

Just to be clear. I am discussing Ruger 10 round mini 14 mags not mini 30 mags.
With the mini 30 10 round mags the problem is not the spring. The problem sometimes is the bottom of the spring moves forward and follower tilts back enough for the bolt to override the last few rounds. My fix is pushing the spring to the rear with a thin screwdriver down the front of the follower. When I see the rear loop of the spring thru the hole in the bottom plate, I put an 8-32 x 1/4 inch nylon screw in the hole. The screw will keep the spring from sliding toward the front. The screw is easy to remove before disassembly.
I have not found any such problems with either 5 or 20 round mags for the mini 14 or 30. The 10 round mags seem like not well thought out after thoughts.
My fixes work for me. If anyone else has other solutions I am open new ideas.

I have some (as-yet untested) aftermarket 10-rd Mini-14 mags. Your approach is simple, and appears potentially useful. The nylon screw idea is an elegant one.

I had a problem with 4 new Ruger brand 10rd. mags for my Mini 30s. In all 4, the mag spring was not strong enough to push the bolt lock all the way into lock position. This occurred in all 3 of my Mini 30s
Ruger said to send them in but before I did, I tried a cut-down AR15 mag spring. Just like you, I left 1 extra coil in and it worked perfectly. I did the same with the other 3 mags and have not had any feeding problems in any of my 3 Mini 30s.

What "Tactics" did you use while testing these magazines?

If you haven't noticed War is coming, and coming fast.

On the 20s and 30s, I did about one shot every second for a couple mags. Any fater than that, and I'd get tossed out of the range!

Well, I decided to have a re-do at the range today. This time I had two factory 77 MK262 clone loads with me (CBC aka MagTech, and IMI Israeli Military Industries 77 grain "Razor" factory loads). This time I did a rest and sandbags to get the most stable shooting. I also had the 581 stainless in the vintage 181 series (shorter) carbine style Mini-14 stock I picked up on eBay.

First I double checked Fed/LC M193 for battle sight at 25 yards. Just over 1/4" center to center at 25 yards with POI 1.25" above POA. Should be dead on to 250-275 yards. 200 yards was closed but I busted some clay pigeons on the 100 yard berm with 6 o'clock hold with iron sights, with the M193.

Then my 77 grain Nosler reloads. At 25 yards, they gave me a 3/4" group which would spread to 3" at 100 yards. Much better than the last time.

Then CBC 77 grain factory. A little over 1/2" at 25 yards with iron sight, so maybe 2 inch at 100. Still good combat accuracy.

Then the IMI 77 grain RAZOR. OMG, one small ragged hole at 25 yards with iron (actually smaller than the M193!) . POI was only 1/4" to the right of the M193 55s. That's about an inch at 100 yards. Without adjusting the sights from the M193, I nailed four out of four clay pigeons at the 100 yard berm.

I continued to plink more using the 77 grain handloads, and still nailed the majority of the clay pigeons on the 100 yard berm. Good enough for practice, anyway.

I am totally satisfied with my shooting this time. With the 77s being only 1 to 1.25 MOA different from the M193, I don't need the tech sights. I did about 200 rounds over the course of an hour, all from Ruger factory 20s and 30s. Zero malfunctions, and no noticeable change of POI as the barrel heated.

I hope this 5.56 ammo shortage foolishness ends soon. While I have 1,000 rounds of M193, about 400+ rounds of the M193 clone reloads, and still have 600 rounds of my 77 grain reloads, but only have about 160 rounds of the CBC 77s and about 60 rounds of the IMI Razor 77s. When they come back available, I'll grab another 500 rounds of either.
