RL-22 in a Ljungman?

[jfred]

Hey everyone.

On the advice of some people here I picked up a pound of RL-22 to try some 6.5 loads in my Swedish Mausers. I'm thinking of bringing along the Ljungman whenever I make it out and then I got to thinking that maybe RL-22 burns too slowly for the Ljungman to handle? I've only fired factory ammo out of her so far, and I hear these things prefer faster burning powders.

34.4 grains of RL-22 (starting load for 6.5 in the Hornady Manual) over a 129 grain Hornady soft point. Do you think that will give me any problems or should I pick up something a little faster?

Thanks for helping a novice reloader

Get yourself some IMR4895 or H4895. RL-22 is too slow. In fact, most all factory ammo is loaded with powder that is too slow burning for the Ljungman. I used H4895. Load to 2500fps with a 140gr bullet and you will be very close to factory velocity with the Ljungman.
Even with the correct powder, this rifle still flings the cases 20 feet or more on ejection, so if you intend to reload the cases, get a tarp or netting or something that will help keep them in the same time zone.

This is a Port Pressure issue with the Ljungmann rifle.

FAST powder, like the military used.

In military service, Ljungmanns were set-up to function in 40 below weather. You do NOT need to use that much gas for warmer weather.

Install a Gas Regulator of some kind on the rifle. The fast action indicated by the distance the brass is being flung indicates that the action is MUCH too fast. It also wrecks the brass. Slowing down the action will give better accuracy, less damage to the brass, less stress and battering on the mechanism.

Yeah more speed and power on the action are not really something I need. Don't want that safety assembly to break. Seems to be the last line of defense between the bolt and my eyeball. How would I go about installing a gas regulator on this thing?

Cheers

I have to chuckle everytime I hear about how far and fast the brass flies out of the Ljungmann rifles.I no longer have mine but we used to joke about guys with these rifles using two targets when shooting them,one for the bullets downrange and another about 30 feet off to the side for the empty brass.I used to lose about half my brass every time I shot the darn thing unless I had a "spotter" for the empties.

Well...you do what I did on mine, after I got tired of chasing brass. The little screw on top of the gas block can be removed, and a new longer set screw, or specially manufactured screw used to block the gas going to the gas tube is used. The portion of the screw that extends down into the gas block has one side filed at an angle, the top side of the screw needs to ne long enough for a jam nut. The solid portion of the angled shank faces the gas tube and blocks the gas entry to it, to adjust, you turn the screw until the angled part of the shank allows gas through the tube. Single load a round and fire. Adjust until you get positive extraction. Load a few rounds and see if everything cycles properly. You may again have to make an adjustment. When you are done, lock in the setting with the jam nut. Your cases should now land about 5-8ft away, (same as garand).

Yeah more speed and power on the action are not really something I need. Don't want that safety assembly to break. Seems to be the last line of defense between the bolt and my eyeball. How would I go about installing a gas regulator on this thing?

Here is what a lot od Swiss shooting ranges use to cath the brass from Stg57s and Stg90s.
Not too hard to make.

like smellie mentioned , replace the small flat bladed set screw on the gas block with a longer allen head screw and nut so you can adjust the amount of gas pressure going back to the action .

once you do this you can run the same slow burning powders that a bolt action will burn , and also control how many miles away the action flings out the brass

in the past with a stock ag42 , I found imr 4064 worked very well .

could you pm me with some weights/loads?
Most places i've seen say minimum load or +10%

I've used varget in my Hakim without any issues, and I have the gas system on it dialed down as low as it will go without turning into a straight-pull rifle.

I've had good luck with 37 Grains IMR 4064 under a Hornady 140 Grain SP bullet (#2630) loaded to a COAL of 3.030" and primed with a CCI-200 Large rifle primer. It does so well I've never felt the need to try others. Keep in mind that this load works in MY rifle, you may have to fiddle with it.
