    Hi all,

    I've looked around the site and while I found some other threads referencing some of my questions, I couldn't find answers to them all. Please forgive me if I missed something.

    Here is the deal, I am comfortable loading shotshells and pistol rounds. However, I've never loaded rifle rounds.

    I am carrying M855s on duty, and want to load 62gr (though not necessarily M855s) for range time. I'm running them through an M&P15.

    I saw some recommendations on loading 55gr, but not 62s.

    Also, the thing that really is confusing to me, is what dies I'll need. I see collet and full size dies and having not reloaded these don't really understand what the differences are. I typically use Lee stuff, and see different rifle die sets and am not certain they are complete or which will be the best for my particular use.

    I would appreciate any help you might offer!

    For an AR you need a full length size die or a small base die. No neck sizing for the AR.

    If you get the newest Sierra or Hornady loading manual they will have a section specifically for the AR. My hornady manual lists a 68gr bullet in their service rifle section.

    Crimping is optional some do some don't I would get the factory crimp die and do that if you want to crimp. RCBS rifle dies all come with a roll crimp installed.

    Ditto what CP said. With the Lee 3-Die set you will get everything you need, including the Factory Crimp Die, which I reccommend for ALL semi-auto reloading, even the relatively anemic .223 as far as recoil. I have had uncrimped bullets end up INSIDE the case. My most accurate loads are with 68 gr. Hornady BTHP or 69 gr. Sierra BTHP Matchkings using H335 powder. If you have a 1:7 to 1:9 twist rate you should get better results with the heavier bullets.

    I normally use 55 gr. Sierras in my V-Match. I have been working on a 69 gr load using H335, 4895, and 4064. I shot some of the 69 gr. loads last week and they were just alright. I had loaded some 55grs with 4064 and started shooting them because I was having so much fun. The 55 gr loads with the 4064 shot far superior out of that gun than any thing else I have ever used. There was one big hole from ten rounds at twelve o-clock.

    Another nod for Lee. I use the 3 die set with the factory crimp die. It crimps very well and will never buckle a case unlike other brands of roll crimp dies. In fact I had to pull a bullet the other day after it was crimped and couldn't pull it with the inertia puller. Would not come out after 20 whacks on the concrete floor!!!! I use the Lee 4 hole Cast turret press and use the Lee rifle charging die with the autodisk powder measure. I can crank out about 300 rounds an hour if I don't have to trim cases.

    For general shooting, I use the Hornady 55 gr. FMJ with H4895, H335, 748 or IMR 3031. For serious accuracy, I use the Sierra 60 grain Varminter HP and 748 powder. Have shot mutiple .6" groups with this load at 100 yds. out of my Armarlite flattop with a 20x scope.

    +3 on the Lee factory crimp die, I'm new at this, but, I've had good results using this die on .45/70, .44mag, and .223. Well worth the few bucks.

    Thanks for the responses guys.

    I think I'll go with 62g armscore bullets and about 25gr of 748.

    I ordered the pace setter die set...we'll see what that does. I think it comes with both the factory crimp and full length sizer.

    I"m thinking I'll just run this through a single press and avoid buying another lee pro 1000 for the time being :D

    Right now, I only have a Lee hand press, works great. Not fast to be sure , but dependable!

    25 gr of 748 is what I use. Where do you work that you carry M-855 on duty? That would be one of my last choices out of a carbine. W-W 64gr Power Points are FAR superior.

    Different tack, which bullet is better, in your opinion for my lar, 55gr or larger. I guess what I'm asking is , what in your experience works best in a RRA lar? I'm not shooting over 200yds, and this is loading for SHTF situations.
    I don't have the time, money or experience to work up too many loads and availability of components, at the moment is somewhat limiting.

    well...for me

    if money is a little tight...and its a SHTF round...i have had good results using any 55gr,62gr fmjbt or tracers with same weights...alliant 2400 powder is a very clean & dependable powder for the .223 or 5.56's.(good for 44mag too)..there is 7000grs. of bullet loading powder in every pound.so when i dont need 1/16th groups @200yrds and want to stretch that lb of powder i go with 14grs of alliant 2400 using 55gr fmjbt winchesters bullets...take a gr. off for the 62gr.fmj's...dont have to worry about a double charge either..the case will over fill...the little 55gainers clocked in @ 2790fps on the chrony...this reminds me...i need to get back to reloading some more 223's...dont have the 15k rds. like i used to...stay safe & keep at it!

    I work in a very small town with very little backup. We field one officer per shift. So, I keep M855s in my AR. If I need to reach a bit on someone inside a car, I can. Likewise, from what I hear, those rounds are devastating in soft tissue, typically producing multiple wound channels. Thereby the argument is that misses are my concern for over penetration. Making even softball size groups at 100 yards still workable. Short of barracades or active shooters, the likelyhood I'll ever use it is slim.
