    Is there any benefit to shooting LC. M855 62 gr. ammunition over the LC XM 193 55gr. in a newer Mini 14? What if any, is the advantage? The barrel is a 1:9 twist.

    From what Ive learned the heavier stuff is sometimes more accurate.

    If it puts holes in something 100yds away, I shoot it! My mini isn't for hunting, it isn't for marksmanship competition. Until I do an AR build, it is my 5.56X45 NATO platform.

    Not sure that the heavier or lighter bullet would make much difference......unless it's cheaper ammo!! :D

    I've been using federal XM193 and it shoots quite well. I just wondered if it was worth the extra expense to go to the M855 62grain ammunition.

    I think I'll stick to the cheaper stuff. After all, the Mini is what it is. Although I have a huge fondness for them, warts and all.

    The 62gr in theary, should be more stable a longer ranges and therefore slightly more accurate. At shorter ranges it would be a toss-up. Use what your Mini likes best...

    200 yards and in, you should see no difference.

    1:9 is best for 55 gr
    1:8 is best for 62 gr
    1:7is best for 72-77/

    I've had better results with the 62gr vs 55gr. You will pay slightly more though.

    5.56 NATO vs .223 Ammo

    Here is a question for anyone who knows...My Mini 14 is about 10 - 15 years old. Can I (Should I) shoot 5.56 NATO ammo through it? I have only been shooting .223 and lately I have heard that .223 is the only ammo I should shoot.
    So what is the truth? Is it okay to shoot 5.56 NATO or not?

    AFAIK, the first Mini's were .223, and only the newest were 5.56.

    It should be stamped on the gun itself. If it says .223 Rem, then only run .223 in it.

    Wiplash,
    Been through this many times. All Mini-14s, with the exception of the "Target Model", are chambered to use both commercial .223 and Nato 5.56. The difference between the two rounds is that the .556 Nato is loaded to a higher pressure. The external dimensions of both rounds are the same. The Nato chamber has a longer feed throat than the .223 chamber. This gives the bullet a longer distance to travel before contacting the rifling lands in the barrel. Some of the different types of bullets used in the Nato ammo have different bullet shapes. Even when seated to the same overall length, one type may contact the lands in a .223 chambered rifle where the other may not. When this happens, it creates a high pressure spike because the bullet has not started it's travel before contacting the rifling. This can be very dangerous in some rifles.

    But, for your question again-------it is safe to use both .223 and 5.56 ammo in the Mini-14. Do not use 5.56 Nato ammo in the Mini-14 "Target Model"...............................................................................

    Thanks for the info guys. I'm going to look at the receiver on my Mini 14 to see what it says regarding ammo. Don't know why it didn't occur to me to look there first.

    I've heard the M-85 is not all that accurite.

    When it comes to AP ammo, better to just find what shoots the best, it's available from several different manufacturers.

    Keep the AP for if it's needed and shoot the best commercial ammo or your best handloads in it.

    My 1-9 Tactical really likes 55 grn FMJ with 25.0 grns of AA2230 and CCI 400 primers.
    Quite a few people say this is a great load. It may need a little fine tuning for your weapon.
    In 69 Grn, the 69 Grn Matchking, 23.0 Grns of IMR 8208XBR, CCI 400 primers shoots consistant .9" 5 shot groups at 100 yds in my Tactical.

    Usual disclaimer, these work in my gun, use reloading info from the manufacturer, don't use my loads unless you do so at your own risk.
