Anybody have quick load? 22wmr and 22lr

[rm_rang]

Hey guys

So i have started reloading rimfire cases with the match head and match paper method. Yes its crazy but I wanted 22wmr subsonic but it’s hard to find and when you do it’s insanely priced

I have got them to fire but i am trying to keep them in the 7-800 fps range and I would like to avoid any further rounds stuck in the barrel. In trying different powders trail boss seems to be the go to as the pulled powder from 22wmr won’t ignight with this priming compound(il assuming its not burning hot enough)

My question is if anyone has quick load could you possibly run a 60gr pure lead bullet sized to .224 through both 22lr(im loading with a 22 short case otherwise my 60gr heeled bullet will make a 22lr case too long) and 22wmr with trailboss and let me know what the charge would need to be for these velocities.

Thanks in advance guys!

The 22wmr is being fired from a 6" pistol barrel and the 22lr from an 18.5" rifle barrel

Gordon's Reloading Tool is free and pretty user friendly.

Okay thanks for that! I guess a couple more stuck in the barrel to work it up.

I should have actually checked before I said that because my memory failed me. It is in GRT, not sure about QL. In order to do things properly you'd need a few measurements of your bullet to build a proper profile. Your OAL is necessary too.

I would try tightgroup it burns so easy and isn't position sensitive and you should have no issues lighting off even .5gr in that case.

Or blackpower and a wad or two to get the fps

What is the length of the bullet?

What are your over-all lengths in each case?

What are your case capacities?

Just for S & G's, I used the proven scientific method of S.W.A.G. and came up with a case capacity of 4.0 grain, a C.O.A.L. of 0.800", a bullet length of 0.600" [yielding a 1 calibre seating depth] for your hypothetical 60 grain bullet out of an 18.5" barrel & ran the numbers through QL.

It does NOT look good. In order to attain your desired muzzle velocities, your muzzle pressures are going to be VERY low, ~400 psi, no matter what powder you choose.

It has been my experience over a lot of years, loading the old British Rook rifle cartridges, that any time you have muzzle pressures of less than 700 psi, you're going to get bullets stuck in the barrel. Mind you, those barrels were usually ~26" long or longer.

The other problem you are going to run into is bullet stabilization. The 1:16" twist used in .22 RF barrels is designed for a 40 grain bullet. Even running quite long for calibre 60 grain bullets out of a .222 Remington with a 1:14" twist at substantially higher velocities than you can generate in a .22 Short, Long or .22 WMR case, bullet stability is non-existent.
