I have several Ruger rimfires, and the .22 drought has been frustrating.

When one of the online retailers had Aguila Super Extra Lead Standard Velocity for .07 per round shipped if I bought a case, I went for it. Aguila seems to have a decent reputation around the net.

As far as accuracy goes, it's better than I am, but I'm having feeding issues. The 22/45 often fails to pick up the second or third round in a magazine, sometimes stovepipes or catches the cartridge at an angle coming out of the magazine.

My old Standard Model that I used to shoot bullseye with (back when I had less money and better eyes) is somewhat less finicky, but has similar issues. The 10/22 sometimes fails to feed, but I haven't shot it much with this ammo.

I thoroughly cleaned both pistols and still have the same problems.

Both pistols only seem to have problems with the first half of the magazine. If I only load with five, no problems, so I assume it's a combination of drag on the bolt from a fully-loaded magazine, the weight of the bolt and the recoil spring.

I got a new recoil spring from Ruger, removed the springs from the two pistols, and using a digital scale compared their strength. Pressing down on the spring showed the old Standard Model was about 4-5#, the well-used 22/45 a bit over 5# and the new spring almost 6#. Hardly a precise way of measuring, but it gave me an idea of the relative strength.

Swapping the lightest spring into the 22/45 didn't improve the FTF issue. I'm not sure if cutting coils off the spring will help, and how light I dare go, but I have a case of ammo to use, so would like to find a work around.

Anyone else found a way to get any of these firearms to be more comfortable with Aquila Super Extra Standard Velocity? Am I stuck loading with five rounds?

I saw a reference to modifying the 10/22 to be happier with standard velocity and will have to chase that down.
