Bull81 RRT



  • Been following everyone’s range report threads and find them interesting. I shoot pretty much daily and decided I might as well start one myself. Worked on load development for a precision AR I have. I’ve had the rifle for a while but never really worked a dedicatedload up for it. Started at 23.2 grains of 8208 and the 73 eld’s and went up to 24. Looking pretty good may load up a 24.2 and 24.4 charge and see how wide this node is. Groups were fired from left to right starting with 23.2 gr.

    This is 23.8 and 24 grains thinking about going higher to see how wide the node is, there was also a velocity flat spot here only 7 fps difference.

    Good! It's amazing how many myths get destroyed when you start tracking performance and measuring things analytically. Turning it out in the public domain keeps you honest. :)



  • No groups today, it’s cold as hell and raining. I did test 24.2 and 24.4 grains over the chronograph though and the velocity flat spot wasn’t there. At 24.4 grains I had some primer flatting but no ejector swipes so I know I was getting up in pressure. Probably settle in at 23.9 right in the middle of the velocity flat spot from yesterday.



  • Tested the Nosler 130 gr RDF’s this morning with varget from 36 grs to 37.5 in .3 gr increments. Not going to test any further, I ran into pressure signs at 2800 fps which is only 45 fps faster than my go to load with the 140’s. These are jumping .050 right now and I can’t get closer to the lands and still keep a reasonable amount of the bullet in the neck. Could probably eliminate the flyers with seating depth adjustments but I don’t see these being worth the extra testing.

  • Well yesterday I picked up my BigHorn TL3 .223 that @tscustoms built for me. Found a good deal on another CG Extreme trigger which showed up yesterday as well, so last night I installed the trigger and mounted the optics. Got it out this morning to do a barrel break in on it with some 55 gr Nosler loads I had laying around. My hats off to Travis, this thing flat out shoots! I’m not going to post any target pictures because I don’t believe they will do the rifle justice. We had 15 plus mph winds todaY and my target hangs from the stand so it kept swinging back and forth ruining random shots. I just gave up and started using the same POI for probably close to 30 rounds. When I was done there was one hole a dime would cover up with single holes all around it from the target swinging back and forth. I’ll start load development hopefully tomorrow and post results. Thanks Travis for an awesome build.



  • Started on load development today for the new rifle Travis built. Wind was still kicking up pretty good today so I used some sticks of fire wood to set at the bottom of the target to help minimize the swinging, it helped but didn’t completely eliminate it. Tested 8208, Varget, and H4895. Just like every other .223 I’ve ever loaded for this one hated Varget, accuracy was terrible and the number were all over the place. 8208 showed the lowest ES and SD’s and H4895 showing the best accuracy at this point. All these loads were with the 80 gr eld’s. Gonna fine tune the seating depths and see if the 8208 load will tighten up. Also got some 80 gr vld’s I want to play with as well. Very impressed with this build so far. Green is 8208, pink is Varget, and orange is H4895.

  • @bull81
    Have you ever tried Ramshot Tac for heavies in .223? I have had good results with 55-60gr loads with it, better than Varget. For some reason I have a pound of H322 and H4198. I don't remember if I bought it for .223Remington or .222. I haven't pulled the handle on my press in months and have lots of new loads to go shoot I just can't get a little monkey off of my back to go shoot. But it's fixing to change.



  • @bigfoot I’ve never used Ramshot but heard it does good in gas guns. I always try varget cause it’s always highly recommend for .223’s but I’ve yet to find one that likes it. I’ve always had really good luck out of 8208 and it’s usually the first powder I go too for 69 gr and up pills. H4895 is shooting better accuracy wise out of this rifle but isn’t as consistent on ES and SD’s. I’m gonna mess around with the seating depths and see if I can tighten up the 8208 load.



  • @bull81
    I shot the Tac loads in my CZ 527 and I might have shot some in my AR but I don't recall. I have put a lot of effort into trying Varget mainly because I have ten pounds of the stuff. It does ok in my 308 but the .223 not so good. I get a lot of horizontal spread with Varget and the Tac loads were easier to hit a node. I haven't shot anything heavier than 64 grains but they were Winchester Power Points and did terrible. I might grab a pound of 8208 for heavier projectiles and see. The CZ has a nine twist barrel so it may not do too hot over 60 grains. Heck, I have a couple of pounds of CF223 I don't think I have tried yet either.



  • Finished load development on the BigHorn TL3 today. Settled on 23.8 grains of 8208 and the Berger 80 gr VLD’s.

  • Looks like you're a contender this weekend!

    Timin' has a lot to do with the outcome of a rain dance.

    Well my positional shooting could use some work so all this proves is I can’t blame the gun or load for my misses.
