    Conventionally lubed boolits in a 300 BLK AR

    The overwhelming preference for cast in the 300 BLK seems to be powder/Hitek coated. Has anyone shot conventionally lubed and gas checked boolits in their rifle?

    I plan for a target velocity around 1,600 FPS. I have no issue driving conventionally lubed and checked boolits to 2,000+ FPS in lever actions, but this will be a first for me with a gas operated rifle. Cleaning isn’t an issue. Even "really dirty." Rifles need cleaning no matter what you shoot and patches are cheap. Heavy leading or some functional problem on the other hand…

    I’ll powder coat if I have to, but I’d like to get away without that extra equipment and process. What are your experiences?

    I shoot conventionally lubed boolits through my ar15 in 6.8spc with no issues. They are gas checked.

    after having lubed bullets (alox) collect dirt and other grime like it was velcro if not shot right away (you have to have all grooves in the case and not loaded to max length for accuracy or else the lube collects crap), i tried powder coating and never looked back in all my calibers, even the 50/70, which looks cool with purple bullets in that big case

    as a side note, with the 300 b/o, my loads (both super and subs) became way more consistant and not smokey anymore and got tighter groups with the same loads when i pc'd them and i even dabbled with pc in the garands, the yellow and red heads kinda look cool in the enblocs and shot almost as good as fmj. i will never go back to conventional lubing

    I have to agree. I PC everything now. I still use the sizer, but just don't use the lube.

    I have read up on the powder coat process and watched a number of videos. The process looks slow, tedious and messy and requires a nice pile of dedicated bins, trays and racks to be added to my current pile of bins, trays and racks. I don’t want to do it if I don’t have to.

    So… does anyone other than 7br have experience shooting conventionally lubed and checked boolits through the AR platform? I would like to hear about your experiences, whether failure or success.

    I have used straight clip on wheel weight bullets with gas check and LLA lube in my .300BO and 7.62x39. I've also used PC.
    My .300BO with its 1-7" twist did not shoot well enough with either type to keep me interested- so I just use jacketed bullets in it. The 1-10" twist 7.62x39 shot great with both types.
    I only tested at 40 yards- if it won't group at that range, I don't bother trying it at 100yds.

    Thank you for the report. I’m hopeful that I can get the Lee C312-155-2R to work. The long body binds on the forward rib in .223 magazines. I have a couple of dedicated 300BLK Lancers on the away. Fingers crossed.

    I push 145gr GC BLL (2 coats) to 2k fps. in BO. No problem. No problem with PC either. Use a good lube, not straight LLA. Bore is shiny with either and BCG is no more dirty than jacketed. You can also sand down the Pmag ribs. Pmag ribs only contact the next 2 rnds in the mag, may work without jamming. You may need to tinker with seating depth on the lancers to get feed right.
    PC is not messy. Do the shake&bake, cook on a decent hot plate. I stand them on the base, use a 45acp plastic holder (bottom of holes sanded out) to load, then pull it off to cook. No cooking racks. No 'transferring' to an oven. 100 fit on my hot plate easy.

    That’s a little heavier than my preference, but I will certainly keep it in mind if my first choices don’t work out. Thanks!

    I usually go with Lar's White Label Carnauba Red in rifle loads. I have it in the sizer, so that is what I’ll try first.

    Good tip on the PMag modification. I’ve been using USGI 20s.

    If I have to go to PC, shake and bake is the way I’ll go. But I still want to avoid it.

    If I had a good lube/sizer I probably would not have gone the PC route.

    I would say to just use the lubed bullets and see what you get.

    ive done it but its messy. Works if you dont mind cleaning guns in the middle of shooting. REAL dirty if your using a can.

    All I shoot in my 300 AAC AR carbine is the Lee/Harris TL-312-160-2R. Tumble lubed, zero issues at standard velocities (16 grains of RL-7 if memory serves)

    That is EXACTLY the load I was hoping to work to, but with the traditional lube groove boolit.

    A couple of Lancer 20 round 300BLK magazines came today. I have a bag of the Lee C312-155-2R that a friend gave me. They load and feed through the dedicated magazines without binding. Guess I will soon have my own experience.

    Thank you to all that responded.

    I tried it but my PC bullets are so much easier to keep clean and work properly. For some reason accuracy with my 8” 1:7 twist was much better with pc as well.

    Been using the Lee 312 160gr cast in hardball, checked and dip lubed with strait mini crock pot warmed LLA for close to a decade... and while I dont like to give loading recipes,, I push them pretty stoutly,, at like a grain under the powder manuals max for 168gr jacketed.
    I've experienced no gumming up of anything and no smoke I've ever noticed shooting outside.

    I put 20 rounds on target today in proof of concept. The load was 16 grains of RL7 and the Lee bullet that was 165 grains lubed and checked. The book says it should be 1,500 FPS, but I didn’t bring my chronograph, mostly because I don’t care.

    Feed through the Lancer magazines was flawless. Function including last round hold open was perfect. Not a ton of shots, but the barrel is clean, and no excessive dirt anywhere else. I do need to do some tuning on the loads/group with 20 shots into 3.6 inches at only 50 yards.

    Looks like I have another cast bullet shooter. Thanks everyone for your replies.

    I shot a couple hundred of the NOE 247 with a GC in my 10.5" Ar. Everything ran fine but the bolt carrier was full of lead at the bottom of the hole, where the bolt is inserted. It appears the gas port was stripping a tiny amount of lead off and sending it down the gas tube to deposit in the carrier. I powder coated them now and hopefully, that will fix it.
