    You'll see the factory velocities are fairly low compared with Hodgdon load data. I bought some surplus ammo sold as "144 grain" and the bullets did measure 143 grains. The velocity measured from long barrel m/96 - 29.1 inch Mauser was 2576 fps. Other sources show a velocity of 2380 fps from the shorter barrel 23.6 inch m/38 Mauser.

    from what Ive seen in a modern or mauser 98 action that the 6.5 x 55 can really be loaded up. in fact some of what im seeing it can meet or exceed the 260 remington if loaded up to higher pressures. .. it seems to have won a lot of compitions back in the day.

    There aren't many 98 actions in 6.5x55 as most are 96's. The case won't quite handle as much pressure as the x57 Mauser cases as it's just not as strong. It does have more case capacity than 6.5x57 (a hunting cartridge) and this helps keep the velocity up to modern levels. So a 6.5x55 case is larger than a 7x57 necked down to 6.5 but it's not as strong.

    interesting. some of my books show the 6.5x55 only 50-100 fps slower than the 260. I was refering to a 98 action rebarreld to 6.5x55 btw not a original gun. I know a guy who has a 6.5-3006 wild cat and he claims he he used to shoot out to 1000 yards with it. it on a really nice mauser action.

    I have been eyeballing the 6.6-284 possably instaed of the 260 rem for conversion on my saiga 308. I really want a 1000 yard AK. and the 6.5 rounds seem to be the ticket for long long range varmit hunting. im not sure how the 6.5-284 cases will fit in a stock Saiga mag. sorry not trying to high jack this thread.

    The 284 Winchester is very fat. It has a rebated standard rim but the diameter of the case is larger. That might be a problem feeding a Saiga. The 284 Winchester has nearly the case capacity of the 280 Remington. In 260 Remington the length is the same as 308 which might limit bullet weights to about 140 grains but that's not a bad thing. Heavier bullets might fit. The 7mm-08 (7x51 or 7x52) is close to the 7 mm "Liviano" (7x49) that had a 140 grain bullet at 2755 fps. 6.5 bullets do carry a long ways though. It would be interesting if you could get the 6.5-284 to work in the Saiga.

    IM GOING TO REBARREL THAT DAMM SAIGA 308 INTO SOME THING LONG RANGE. IM TRYING TO FIND A FEW 6.5-284 CASES TO PLAY WITH JUST TO SEE IF THEY WILL LOAD INTO A STOCK MAG. ILL START A NEW THREAD FOR IT SO NOT TO CLUTTER UP THIS ONE.

    Well some good news finally. The Remington 140 grain rounds are slightly too long for a G3 .308 magazine. So when he got home and checked, Voila! ... the 110 grain rounds he loads fit *perfectly*

    After looking at those MG links (THANKS for those BTW!!!!) I think the magazines to use will be either the Cetme magazines with their slight curve or the Saiga .308 mags.

    I have some of thsoe 7.5mm mags on order as well. Doubt we'll use them but for $20 it is worth it just to have them to compare things. Since the 8mm mags are a bit too long, these 7.5 mags should be closer to the factory bullet sizes.

    Looking more closely at the follower, I doubt we'll need to do any mods to the magazine.



    Now he is positive he wants to build it up like a PSL. Parts count will be followed "just in case", but I figure with the receiver, barrel, floorplate, muzzle brake and piston it won't be hard to find 1 more part.

    We are talking about making our own handguards because I can't find any PSL handguards anywhere! Does anyone have any idea where we can find PSL handguards? I was hoping that *maybe* someone with a synthetic stock may want to get rid of their wood handguards.

    Interesting discussion. Do you guys think a Romy could be converted to 6.5x55 if light bullets and loads intended for the old surplus mausers were used? My Speer Manual lists 45000 psi as max pressure which isnít too far from the 43000 Iíve seen listed for the 7.62x39. Still, the mild mauser load data shows a 100 gr bullet at 2800-2900 fps which is right there in .243 Win territory.

    read all the info in the 308 conversion threads. the chamber pressure is around the same but the bolt thrust will be higher due to the larger rim diamiter. if you keep the pressures down you can likely use a rommy. how ever there is no guarentes with this stuff. there have been 308 winchesters built on rommy bolts and trunions and so far none have failed. any time you excede the maximum bolt thrust of the round that the gun was designed for you are in uncharted territory. I have several conversions and I feel safe with them but I cannot advise others to follow in my path. there is no hard facts on what a rommy or any ak trunion can take. it is known/ reported that a two lug sagia trunion will not pass the european proof tests in 308 win and that is why there is 3lug trunions in those guns. the m77 and 76 uses a two lug that is very simular.

    I bumped the 308 conversion thread up to the top of the list so you can find it. lots of info for you to read and base your decisions on
