    Default 6.5 Swede velocities

    For you 6.5x55 Swede shooters, what velocities do you get as compared to the published values?

    I loaded some 140 grain Sierra Match Kings with a 43.7 grain load of RE22, as per the Sierra manual. The manual says that should give me about 2600 FPS.

    My ProChrono gave me me a very consistent 2290 FPS - way low. I am always suspicious of my chronograph, but have no way of knowing if it is giving me bad numbers. I am shooting a very accurate M96 Swedish Mauser with a 27 inch barrel, so I'm not losing velocity from a short barrel.

    What kind of number do you get?

    Thanks

    My Swede is a Model 70 (22 inch tube) so take it for what it's worth. I get 2800 fps with 140 grain bullets and RL 22, but I'm using a good bit more powder. I gotta admit I've not checked it against published velocities in a good while.

    US loading data is based on SAMMI specs and as such is somewhat low. European ammo is loaded to European specs and is hotter and travels faster. Go to Midway and check out the difference in velocities between Norma and Remington ammo. I've never personally used RE-22 to load this round as I believe it's too slow for optimum performance and good velocities. I do however load for a M-94 and they have a shorter barrel.

    RE22 is slow, but that is what I had on hand and it listed some of the better velocities in the loading manuals. Brav01, you're right about the loading specs, and the Sierra manual lists substantially higher loads for a M96 military action as opposed to the Speer manual military action loads. I know some of the military action loads are incredibly slow, but I'm showing 200-400 FPS slow. Next opportunity I'm going to borrow one of the range's chronographs and reshoot the same loads.

    Mine has a Carl Gustav action built in 1915. Got it in 1995 when guys were selling stacks of them at gun shows for $125 a piece. I bought two and kept the better one. Absolutely mint and really accurate. Collectors wouldn't be happy since I sporterized it, but it is a fantastic gun.

    Thanks for the link. I'm thinking my chronograph is in need of replacement, my numbers are just too far off. I'd be at the range now, but the wind would blow the targets and chrony over. I'll take -5 degrees and no wind over this mess.

    The M-94s and early M-96s were pressure tested for 66,000 psi and were made of a special Swedish steel designed to allow a small action to perform to large action specs.
    MY M-94 has a 17.5 inch barrel and requires a faster powder to make velocities over 2300 fps, RE-22 just doesn't fill the bill.
    As far as sporterizing a Swede, if you hadn't somebody else probably would have; Unless you intend to shoot militay matches with it or sell it to a collector you've still got a great shooting rifle.

    You're welcome. Dead calm and +20 here north of the hill.

    The Barrel of an unmodified m/96 Swedish Mauser is 29 inches with a 1 in 200mm twist rate.
    The m/38 rifles have a 23.5 inch barrel and a 1 in 200mm twist rate.
    The m/94 carbines have a 17 inch barrel and a 1 in 200mm twist rate.
    The CG-63 Target Rifles have a 29 inch heavy barrel and a 1 in 220mm twist rate, unless they have a Schultz and Larsen barrel which has a 1 in 9 inch twist rate.

    Some of my loads over a Chronograph. I just picked out some with a 140 grain bullet for you... I have LOTS of data for the 6.5Swede. But most of it is in written form in my testing log book.

    REMEMBER SOME THINGS CAN MAKE A BIG DIFFERENCE IN VELOCITY. 1. Brass brand 2. Primer Brand 3. Rifle bore /chamber condition 4. Seating depth 5. crimp pressure, 6. air and ammunition temp.

    Thank you Float, this is one of the caliber I'm loading for and I didn't realize the difference the various mausers made on what you load.
    It makes sense, I just hadn't thought of it...

    I have a couple 6.5x55 Swedes. 2-96s and one on a 98. I standardized a long time ago with Lapua brass 51-4831 and 140 gr bullets and I get 2800 fps (=,- 25 fps depending upon rifle). When I use Win brass, I drop back to 50 gr and get similar vel. 2777. Approach carefully because this is above most books. I have never had brass stick and primers are solid and clean. The Lapua brass has been reloaded a dozen times and primer pockets are still tight. So it works for me. But maybe not for you. J.

    Slug your bore. Swedes can very by several thousandths in groove dia, so if you have a wide groove barrel, your velocities will suffer. You're shooting .264" bullets and if your barrel measures .266" or more, it will definately cost you velocity.
    Those that are successful in Alaska are those who are flexible, and allow the reality of life in Alaska to shape their dreams, vs. trying to force their dreams on the reality of Alaska.

    If you have a tenuous grasp of reality, Alaska is not for you.

    Just checked the muzzle with a micrometer. It is .264. I'm going to shoot over two chronometers side by side this week to get a good comparison.
