I own a Mini 14 223 rem and wanted to know what is the best ammo for self defence. Should I go with a heavier or lighter gr. I currently have Winchester JHP 45gr in it. Is that ammo good or should I go heavier.

It all depends how far is your "self defense" object.? If close range like in your home, than it doesn't matter, all does the same job.:21:

Heavier, unless blowing little chunks off of intruders is your primary intention.

Too much blood for my liking, heck a melon shot would take days to clean up.

I believe all current Mini 14s have a 1:9 twist. Older ones might have been 1:12, but don't quote me on that. You might find the info in your owner's manual for your particular rifle; I just checked the Ruger site.

You also want to heed Ruger's warning about only using 223 Remington ammo. It is not designed for use with the hotter Military 5.56 ammo.

Older mini`s had a 1:10 if I recall correctly.

Mine was made in the 90's. So what ammo do you guys use for .223 rem.

If sargenv is correct--and I have no reason to question him--then do not use 5.56 x 45mm NATO-spec ammo like XM193, XM855, the 5.56 Hornady TAP, Black Hills Mk 262 Mod 0 & 1, etc.

As long as the ammo is .223 Remington-spec, it should be fine in your rifle.

As sargenv indicates, 5.56 is a hotter load with higher pressures than allowed by SAAMI specs. IIRC, there are also minute differences in chamber dimensions around the neck (leade, perhaps?). So, just stick to ammo that's labeled .223 Remington and you and your Mini 14 should be fine. There are plenty of good options in .223 Remington for SD/HD use in the above-mentioned FAQ.

Minis had a several different twists over the years. Here's a set of guidelines I got from another web site, but you may want to measure to be sure.

series 180- made in the 70's
rifling 1:10, has a wood hand guard with metal band and the bolt lock is protruding

series 181-182 made in the early 80's
rifling 1:10, wood hand guard no band, current bolt lock design introduced.

series 182-185 made mid 80's
rifling 1:10, plastic hand guard introduced

series 186- made late 80's early 90's
rifling 1:7, ranch rifle introduced about this time

series 196- made 90's 2000's
rifling 1:9

series 197- made 2005-current
rifling 1:9, new front and rear sight, new stock buttplate, new receiver design styling

This doesn't address the OP's question but thought I'd share some info directly from the Ruger Owner's Manual to help clear the FUD that I see all over the internet regarding newer Mini-14's and 5.56mm ammo:

AMMUNITION
The RUGER® MINI-14® RANCH RIFLES are chambered for the .223 Remington (5.56mm) cartridge. The Mini-14 Ranch Rifle is designed to use either standardized U.S. military, or factory loaded sporting .223 (5.56mm) cartridges manufactured in accordance with U.S. industry practice. See “Ammunition Notice” & “Warning - Ammunition,” below.
USE ONLY FACTORY AMMUNITION LOADED TO U.S. INDUSTRY STANDARDS

Instruction Manual for RUGER® MINI-14® RANCH RIFLE (http://www.ruger-firearms.com/Firearms/PDF/InstructionManuals/55.pdf)

I'd like to adress a couple bits of misinformation about the mini that I see here.
first is the twist rate, from Ruger.
****************************
TWIST RATE FOR MINI-14

1978-1985 = 1 in 10" (e.g., 181 series)
1986-1994 = 1 in 7"
1995-2004 = 1 in 9" (e.g., 197 series).
2005- = 1 in 9"
So if you know your year of mfg, you're good to go. (Ref above post)

TWIST RATE FOR MINI-30

ALL MINI-30 = 1 in 10"

Otherwise, you can check by pulling out a tight fitting patch from the bore with the cleaning rod marked so you can count one complete rev - then simply measure the distance the rod came out. I did this and came pretty close to what my 196 actually is (1 in 9").
************************8

Next is this statement


You also want to heed Ruger's warning about only using 223 Remington ammo. It is not designed for use with the hotter Military 5.56 ammo.

Go here, http://www.ruger-firearms.com/Firearms/PDF/InstructionManuals/55.pdf, and go to page 11. This statement applies to all Ranch Rifles, including the Target model.

Here is what it says.

AMMUNITION
The RUGER® MINI-14® RANCH RIFLES are chambered for the .223
Remington (5.56mm) cartridge. The Mini-14 Ranch Rifle is designed to use either standardized U.S. military, or factory loaded sporting .223 (5.56mm) cartridges manufactured in accordance with U.S. industry practice.

See “Ammunition
Notice” & “Warning - Ammunition,” below.
USE ONLY FACTORY AMMUNITION LOADED
TO U.S. INDUSTRY STANDARDS

In addition, if you go here, http://www.ruger-firearms.com/Firearms/PS-InstructionManuals-RI.html, and look at EVERY model of mini 14 listed, even out of production models, it says the exact same thing.

For me, I'd use a std 55gr soft point. It will open enough to do considerable damage and not limit your longer range effectiveness like the 40gr pill would.

i just measured my twist on my 186 and it is a 1 in 9

how i tested it took sharpie put straight line on side of "cleaning rod with brush" marked muzzle where line met slid in letting it rotate when the line matched my muzzle mark i stopped and marked the rod it was 9 inches between the marks

so check your own but 186 having 1 in 7 is not absolute

186-70xxx

I see where a poster noted that the manual says 5.56 is ok...

Pretty much whenever the name "Mini 14" comes up it appears some people say that you can NOT run 5.56 in it...

But where did you find it to say that?

I ask because my OEM ruger manual says you "CAN" shoot .223/5.56 and the most importantly the head engineer at Ruger told me the Mini 14 is actually chambered in 5.56 but that .223 was put onto the rifle... (don't quote me but i think he said .223 was put onto the Mini 14 to make it have a more "civilian feel" to it...

Again, study the AR15.com FAQ. With a 1:7 you can easily run 77-grain, but the lighter 45-grain bullets should also be very shootable.

That said, you need to test the loads with your own rifle, because each firearm has very particular tastes. While one load will shoot poorly in one weapon will be outstanding in another, even if it's an identical model.
