    Some years ago I bought a Baikal 9.3x74R O/U. It's somewhat agricultural but has given me a taste for doubles and for the calibre. What I want to do is upgrade to a better quality rifle in SxS with ejectors.
    From a paper ballistics point of view, the 9.3x73R and the .375 Flanged Magnum are very similar. Although I haven't seen much info on heavy for calibre projectiles. Any thoughts or experience would be appreciated.

    For me one issue is the availability of ammunition and components.

    In my country I know I can reasonably easily get 9.3x74R cases, but haven't seen .375 Flanged Magnum around (until now I haven't been looking). .375 projectiles are much more widely available and in a greater variety of weights and construction.

    What I don't know is how easily available factory ammo would be in Africa for each of these.

    Realistically, there is little to chose between them with respect to actual performance on game. However, the .375 flanged is pretty much universally legal for DG in Africa - not so the 9.3. Factory loaded .375 flanged is relatively hard to find. In this country, Nosler loads it's 300 gr Partition in it, and it is currently available for about $8.00 US a round through places like Midway Arms. It would be very hard to find in the RSA. The 9.3x74R is a much more common caliber, with a large European following.

    If you reload, the flanged .375 is a great option - particularly in a double where you likely will have to come up with a load that regulates in your new rifle. As you note, lots of bullet options out there. Unfortunately, .375 Flanged rifles are almost as scarce as the ammunition for them - though perhaps that is not the case down under?

    Norma does sell 375 flanged, but it’s not cheap.

    hunter,
    you can find 9.3 bullets in oz - you just have to look harder.
    brownells is one source if you are prepared to wait.
    swift and barnes are to be found as is woodleigh and hornady and speer and norma if you ask a dealer to order for you.
    the 286 swift would be a good all round bullet and one that might be likely to regulate in a double, as long as it was not set up for lighter bullets.
    although the 9.3 x 74 is a little less powerful than the 375 flanged, use of good bullets in the 9.3 can narrow the gap.
    bruce.

    They are almost a ballistic twins. factory loads in the 375 are 300gr at 2400fps, and the 9.3 is 286gr at 2380fps. My 9.3 double I have a 300gr Swift aframe load that is super accurate in my rifle. It is 2370fps at the muzzle. I have owned 4 different 9.3's and handled 50-60 others. the 375 Flanged I have only ever seen in person 3 of them and never had a opportunity to shot one. Both of these rounds will hunt any of the plains game and depending on country legal for dangerous game in the 9.3. The 375 meets the letter of the law in min of 375 for dangerous game hunts. Both should only be used on dangerous game by a very patient hunter that will wait for a good shot to the vitals and be a competent enough shot to make the shot under pressure. I would also make sure you and your PH are in agreement on you using either one on DG.

    Ammo and brass are much easier to find for the 9.3's.

    dave, that 300 gn load sounds like a good one.
    i can vouch for that bullet at 2400 fps on 600+ kg game.
    it handles that game so well i would not hesitate to use it on somewhat heavier targets.

    @bruce moulds It is very effective, I have shot everything from Klipspringer to cape Eland with my 9.3 and nothing has required more than one shot.

    I love my little Borovnik 9.3x74R. Handles like a shotgun and kicks like a sissy. 20180621_211336.jpeg
