    I just started loading for my Mini14 223. I purchased IMR4198 powder. What loads and bullets have you found to have very good accuracy (<.5" MOA at 100yrds)?
    I have a bull barrell on my Mini and its accurate within 100yds. I have a post of it in Ruger Forum. Will try to post here.

    I load a 55 grain Hornady FMJ-BT with 24.8 grains of H-335 and get this from a stock Rock River carbine at 120 yards.

    Just out of curiosity, why'd you pick 120 yards to shoot at?

    I can't quite shoot as good as RustyFN, but my findings concur with his, and my RRA also shoots 55 gr VMAX and Hornady SPP equally well at that loading

    The target stands were already set up there. I didn't know the exact distance but figured it was close to 100 yards. Another guy came to shoot and shot the targets with his range finder and told me they were at 120 yards. I belong to a private club and the range doesn't have yard markers.

    Mt favorite 223 load is 25.0 grains of H-335 with a 55 grain bullet and a magnum primer. Either Remington 7 1/2 or CCI 450 primers. The Winchester, Federal and non-magnum primers have thinner cups and can pierce in 223 rifles. Avoid Federal cases are they are very thin in the case head.

    Is your IMR-4198 made in Canada or Australia? The older version is made in Canada and this is the IMR-4198 that most load guides use. The newer version is made in Australia and is the exact same powder as H-4198. Hodgdon claims that interchanging the load data between IMR-4198 and H-4198 is safe though.

    Same here Horandy 55g FMJBT w/c, 24.5g TAC at 2.200 is my go to tactical match load. At 150 yards and closer it's does well enough for me, I don't use a scope with just a red dot or irons can consistently hit the A zone of a USPSA/IDPA target.

    I'm going to be getting a new 1-4 scope soon and have been playing around with 62g Sierra match kings with 23.3g of TAC. I'm going to chrono first then check out accuracy after I sight in my rifle with M193 after the scope is mounted.

    I load the Hornady 55grain FMJ-BT bullet over 26.5gr. of Hodgdon's BL-C(2) for great accuracy in my AR loaded at 2.225"col.
    H335, WW748, and TAC all produce very accurate loads in .223 and meter like water in powder measures. Experiment with these and see which works best for you.

    That's my standard loading for 55gr too. COL may vary depending upon trim length as I seat to the cannelure.

    25.9gr Tac - 55gr V-max - 3043ft/sec avg.

    In my rifle this load just shoots more accurately than loads above and below it. It seems to have hit the resonance of the barrel.

    25.0 gr of Ramshot Tac under a 55gr m193 pulled bullet. I get 1.5 inch groups at 100 yds with 14.5 inch barrel.

    DanaT - your load is way above Ramshot recommendation (max 24.7gr) per their chart. Any details on the rifle you are using and brass.

    I when to the range yesterday, I had worked up some loads from 20.5, 20.7-best, 20.9, 21.1 21.3 (10 rounds each) . None all that impressive. I would manage to get a few tight groups but then would have a flyer. See picture below. I plan to go up on the charge to where some of you have provided (>22gr<25gr). This time will only use LC Brass............

    I've used Varget (25 gr.) and TAC (24 gr.) in my Mini-14 and both produced very good results. I chose TAC as my primary powder because it's less expensive and it meters very accurately, so I don't need to drop single grains like I did with Varget.

    That said, I don't get .5 MOA, but I'm petty much shooting the Mini for combat type of accuracy only. Mine isn't a target model so I don't expect it to drive tacks.

    I've used 55 gr. Hornady 55g FMJBT w/c, 55 gr. Montana Gold and M193 pulls. The Hornady were probably the most consistent, but even the cheap military pulls worked well enough for my purposes. I don't think I would recommend them for yours though.
