    I just picked up a Swedish mauser in 6.5x55. I was working on some loads today and tried some 4064 with pretty good velocity numbers. It has the original 29" barrel and with 38.5 grains of IMR 4064 I'm getting 2550 f.p.s. which I read was the standard factory load velocity for these rifles. I also tried some IMR 4350 up to 42 grains and got 2500 f.p.s. Since I'm not real familiar with these rifles I wanted to know if these were safe loads for the old Swedes. Forgot to add that I'm using 140 grain Sierra matchkings. (Guess that would have helped, huh?)

    Thanks,
    Marty

    Used to use both when I had my Short Swede along with 3031 - all gave good groups with mid-range loads

    Oneounce,
    Do these seem like reasonable loads for a 1910 Carl Gustafs Swede?

    That's the same load data I use for my CZ 550, with 130 grain Nosler AccuBond bullets. I get good accuracy and very little recoil. Not much of a comparison to your older rifle, of course, but it feels like a very mild load.

    Mine was a 1907 with the carbine barrel - I got 1 to 1-1/2" three shot groups at 100 yards - you have 11 more inches than I did...........mine preferred the SMK 120 and SMK 140

    Most folks like RL-22 or 4350.

    Military ball would be 2511 fps at the muzzle from the 24.5 inch barrels of the M-38. With 139 to 142 grain bullets, Reloader-22 is your best friend. I use 45.5 grains in my sporterized Swede with 140 grain Sierra Matchkings and Hornady SST's. My average velocity is 2513 fps. I was trying to duplicate the velocity and keep the pressures safe for the action. The last group I shot was with a new lot of brass at 200 yards with the SST's. 3/4" from the original barrel.

    I tried IMR 4350 it shot well. No reason IMR 4064 should not work but I really think this case is better suited to a slower burning powder.

    I consider my load to be equivalent to Swedish ball. It shot well too.

    If you consult the Hodgdon online database, www.hodgdon.com, they list 38.0gr of IMR4064 as a Maximum load for the 140gr Speer and the 142gr Sierra. I would not test your action with any higher load of IMR4064.
    As to IMR4350, your 42gr loads are on the mild side and that powder may still have more potential to offer.
    I have used H414/Win760 (same powders), H4350, Alliant Rel-19 and Rel-22 in my Swede, and all have good potential. I have a tendency to avoid the older IMR powders due to their temperature sensitivity issues.

    Thanks for the replies. I just loaded 10 of each so I may just go with the 4350 if I get good results with the groups.

    I would agree in my M700, but to someone shooting a vintage Swedish Mauser I think it better to leave it at ball equivalent. The Swedes used plain carbon steels throughout production and I don't know where the edge of the envelope is, and don't want to find it. I assume ball equivalent is perfectly safe and that is what I will recommend for a M96.
