These are called Low recoil low noise shells not lite. Velosity is only 980 FPS. Lower velosity means lower preasure. 980 FPS is also subsonic.

I have some experience with them (the 980 fps Winchester loads). They probably hit a target just fine, but don't always sound good. I'm afraid that the powder they are using is not as fast as it should be for such loads. I have freezer tested the lightest RST loads and found them to be reliable and of good "sound" even when frozen. RST must have access to very fast powders that Winchester does not choose to use.

Lower velocity does NOT mean lower pressure! That is a logical assumption but unless you have measured the pressure you cannot be certain of this. Luckily Sherman Bell conducted a test on the subject ammunition and provided the results in writing, albeit that was 14 years ago.

How do we find out the pressures of box ammo?
I have been on the Winchester site and it does not state the pressure of most of there shells.
