I wanted to ask if really the kleenmore primers better than cci or the Winchester's? I read the forumn about crud and not being so and they are not near as hot,but it is hot what you really need to burn 3 pellets or 110-120 grain of powder? The 777 or Pyrodex is not smokeless powder and we use so much more of the stuff. Has anyone use the 209M by CCI?
I have good luck with the Winchester, but used the Kleenmore and I feel they arenot any cleaner than Winchester.

Are you sure the Remingtons you used were Kleanbores... not the Remington STS's?

It's alsopossible that a mixup occured at the packaging plant where both areboxed & your Kleanbore box contained STSs by mistake.

There's a noticeable difference between the remnants of both primers. If the remnants were the same for both, then what you shot was not the Kleanbores.

I HAVE TO AGREE WITH TRIP-7 THERE IS A DIFFERENCE
IN THE PRIMERS. I'VE USED CCI WINCHESTER BUT THE
REM KLEEN-BORE REALLY WORK FOR ME MY SET-UP IS
100GR. 777 IN PELLET FORM 225 AERO-TIP POWERBELT
WITH THE REM KLEEN-BORE PRIMER. I THINK I WOULD
CHECK MY PRIMER BOX YOU MAY FIND THEY WERE NOT
KLEEN-BORE.
