Thank you in advance.

    You will have better luck with the federal primers. BLC2 is very heat sensitive. Be aware of this if you are near max and it is a hot day.

    Thanks, that's good to know ... I was looking for Varget but BLC2 is the only powder I can get locally. Do you have a powder recommendation that you don't mind sharing, just in case I ran into one.

    Thanks again.

    DON'T MIX HEADSTAMPS. Different manufacturers have different brass thickness, which equates to different internal capacity. One case by one manufacturer, may be fine near max, and one by a different manufacturer, may have a lower capacity, thus raising internal pressures beyond acceptable limits.

    When working a load, use only 1 headstamp. When switching, back off 10% from the accuracy load, and work back to it with the next type of brass.

    I figure you already knew this, but maybe a newbie is reading this post.....

    Load overall length to fit in a magazine, regardless of what a book says. Develop max load using the same length. Where is your primer pocket swage?

    I use win 748 ( 26 gr. ) & H-335 ( 25 gr. ) with a 55 gr FMJ for plinking with the bushmaster .

    Also , check the OAL of your brass , all the brass I picked up here & there were between .010 to .020" over max length .

    Have fun and enjoy that evil black rifle [:)]

    another 748 user here. love the stuff. I always shoot 55gr bullets out of mine and regardless of bullet brand, medium loads always shoot the best groups. No need to load to max for anything other than testing and seeing what it does.

    Thank you all for your sound advice.

    Size correct. Check that sized brass chambers and ejects easy(before primer or anything). If doesn't , most likely didn't push shoulder back.

    Components should be fine. Although I have never used that powder. I like X-Terminator or A-2015 for 50-55gr bullets. Also use TAC and XBR-8208.

    Never had a slam fire, but have heard Winchester primers are the softest. Tula/wolf primers seem to do well, I also use many CCI in my AR

    I use same load in Win brass, LC, Federal, PMC and some European brass, never had an issue. I also run at max 223 loads. As 5.56 runs at higher pressure, check Ramshot's or Accurate's web site. They now list higher load data for 5.56 and rifles approved for "NATO ammo".

    I've had good luck with 50-55gr bullets with twist as tight as 1/9. I am currently getting a 1/8 barrel to try with 60-64gr bullets for some hog work. Maybe that new Nosler bullet!?

    I fully agree, just making sure I'm not forgetting anything on the safety aspect and avoid dealing with Murphy.

    Thanks again to all, I really appreciate your willingness to share your personal experiences.

    Sorry, I couldn't resist.
    You'll 'prolly need to full-lenght re-size, maybe even small-base...I don't reload for an AR, so my .223 powder favorites might'nt work for you, but I've had good results with Ramshot Tac, X-terminator, W-748, yada, yada...DDO segregate your brass as mentioned previously, and of course, start mid-range or lower with listed powder charges......Good luck, be safe and have fun!

    Good point. Lots of charts and graphs out there on 223/5.56 H20 case capacity. Here are a few examples. Note the 5.56 Military brass has more case capacity then it's civilian brother.

    here is a good read on the 223. Note the case capacity chart, 5.56 has more capacity than 223.

    Also note that the difference in case capacity from 223 to 5.56 of several different manufactures is minimal at best.

    I have loaded up a few hundred with BLC-2 using the recipe for 55 grain bullets on the jug. They chrono about 40fps under factory ammo and group out just as well.

    Thanks for this post! I'm going to start my first run with reloading .45 ACP and clearly, I'm going to have to rethink this!
