    I'm in the process of working up 30-06 loads for a July 2020 Limpopo Plains Game hunt, to (hopefully) include BWB, Zebra, Gemsbok, and Kudu, plus some smaller animals. Looking for favorite 30-06 load data with the 180 grain Swift bullets, or similar.

    These are my top bullet choices for a new Tikka 30-06 with 22.4" barrel.
    I'm using new Lapua Brass and F210Ms.

    I'm using H4350 to start with and getting "fairly good" results so far (~MOA) with the 180 Scirocco at .080 off "just touching" the lands, (with 54.0 grains H4350). A couple with this load did 2,703 fps over a Magnetospeed.


    Initial with the 180 AF has been pretty so-so thus far at .051 off and .076 off the lands (best was 56.0 Gr H4350 at .051 off).

    Additional powders on hand include RL16 and RL17. Any 30-06 experience with these, especially with Swift bullets, would be most helpful.

    Thanks!
    Joe

    I prefer the 165gr A-frame. Usually they shoot well backed off the rifling. If you have shot regular jacketed bullet you need to super clean the barrel before shooting the pure copper jacketed Swift bullets. I start with Wipe-out then Sweets 7.62 or Barnes CR-10 and last with Butches Bore Shine. If the barrel shows a lot of fouling I repeat until really clean.
    That is all the help I can give. I used A-Frames when we and I alone went to Africa with excellent results. We(I) took 257R(120gr), 257W(120gr), 30-06(165gr) and 338win mag(225gr) for our(my) hunts. The 1st trip was with my daughter and the 2nd I went alone. Had a great outfitter and brought home a bunch of book animal as well as had a great time with spot-n-stalk hunting for PG.

    Looked at my records and I ended up using 150gr Barnes TTSX in the 30-06. Sorry for the confusion. I did try the A-Frames but wanted more speed in a short barreled rifle. The TTSX work well also and require the same tips as for loading Swift bullets

    Absolutely correct on the bore cleaning, Divetnhunter. I use Bore Tech normally, and used it plus J-B bore Paste just before starting the Swift loads.

    I had good luck with 165 gr A-Frames in a .308 (using RL17), but thought I would go heavier for the 30-06.

    Thanks for the information.

    With 180gr bullets in an ‘06, I tend to get the best combination of accuracy and velocity with H414. IMR4350 gives me slightly better accuracy but H414 gains me ~60fps. CCI200 primers. Note: My ‘06 has a 21” barrel.

    While accuracy is important, IMO dependability trumps both velocity and accuracy if both of those are good. I don't mess with bench rest loading max accuracy techniques too much and prefer to stay on conservative side of pressures/velocities. Both of those bullest will do fine just pick the one that is most consistent somewhere between 2500 and 2700. I also like the temperature insensitive powders for hunting purposes. I'd try 4831 SC.

    Yeah, the goal is not to get 300 H&H velocities, but I am a bit of an accuracy freak.

    FWIW, this is only my second 30-06 - but the first one was from about 50 years ago. :yikes! It was also my very first centerfire rifle.

    I continue to tweak the H4350 / Scirocco 180 gr load. Today's, seated a bit deeper, shot close to MOA at 100M on paper (4 shots), and did 3" at 325 Yds (3 shots), on steel.

    Also tried a few with RL16 just to get a feel for this powder in the 30-06. And it's pretty zippy as expected. Alliant has some limited load data for this powder, (none specifically for Swift bullets.)

    FPS makes for a flatter shooting round which make guessing ranges less trouble. Speed also gives better terminal performance. I look for speed with accuracy in my hunting loads and it has worked well for many years.
    The Sirocco really likes bullet jump. My groups shrunk with more jump---Just like Barnes bullets

    I'll have to give Redding a call. My competition seater die was max down with today's loads at .086 off just-touching the lands (180 Sciroccos). Screwing the die body down as far as I dare only gets me another .007.

    The box of factory Remington/180 Sciroccos I bought were .116" off.

    The "zippy" RL16 load (loaded four, chronograped just one), ran 2,764 fps. No pressure signs, but group size was so-so.

    In my experience the Sciroccos can be very finicky to load for - think is because of the veery thick copper jacket. My best results (165gr in a 30-06) were with at least 2mm of jump - both with IMR4350 and VV N550 - although I’ve now moved to the Accubond.

    The 180 Scirocco work-up appears to be in the books. The Tikka-H likes the 180 Scirocco at .087 off the lands with 54.2 grains of H-4350 and F210M primers.
    In fire-formed brass it did 0.6 MOA (1 1/4" or a tad more) for three shots on steel at 219 Yards, (my usual target for setting Zero). This followed three at ~0.63" at 109 Yds.
    V for 3 more over the Magnetospeed averaged 2,716 fps, which is a little higher than the Swift manual shows.

    The 180 A-Frame shows promise at 56.3 gr H-4350 and about .040" off the lands, but no cigar just yet. Unfortunately, the A-Frame does not print to the same POI as the Scirocco.

    180 grain Swift Sciroccos, 180 grain A-frames and H4350 are all I use in Africa. I use them for culling and have shot over 150 animals with these loads. Mostly zebras, wildes and gemsbok. 56.5 grains of H4350 for both. The A-frames print about 4 inches lower at 100 yards than the Sciroccos. I have a 24" Pacnor barrel with 1/10 twist.

    Thanks, JMM.
    Your comments on the 30-06 / 180 grain Swift performance - in a couple of threads, were a big part of my decision to go this route.

    Thanks. I just got back from a culling trip. Nothing but Sciroccos and A-frames. I shot wildes with Sciroccos and zebra/gemsbok with A-frames.
