Autocomp and w231 powder puffs


Recommended Posts

I loaded 2 loads for comparison today.

1st was 124 grain copper playted with 3.5 grains of w231. Cycled fine in a 1911 with ported barrel and made 850 fps.

2nd load was a115 copper plated with 4.5 grains of autocomp. Chronoed 900 fp.

Ther was a ver distinct feel between the loads. The w231 was soft at 850 but the autocomp was way softer at a higher velocity. Felt like a airsoft gun. I'm going down to 4.2 of autocomp just to see how fast and if even softer. Using for steel challenge.

The 124 was at 105.4 PF and the 115 was at 103.5 PF, so the lighter

bullet was a little "less powderful".

I'm surprised there was a "way softer" feel, when they're so close

to one another.

Both are very soft. I've shot some 100 PF loads in my 9mm and

they are a LOT of FUN to shoot - but I never notice a large difference

from one powder to another - they're just silly soft - and FUN to shoot.

Be interesting to see how low you can go. :cheers:
