Shot my first reloads this morning.

To add to the theme of the thread...

Just got back from shooting my first reloads:
-I took a box of factory Winchester .38 special
-20 rounds of 6.6 grain Power Pistol and 110 grain bullets also,
-20 rounds of 6.8 grain Power Pistol and 110 grain bullets.

Winchester primers

Shot 8 of the factory ammo thru the S&W 627 - light recoil
Shot 8 of the 6.6 grain with similar or slightly more recoil w/ increased flash
Shot 8 of the 6.8 grain with a bit more kick and flash.

There was quite a difference in those .2 grains

I did notice that the factory ammo is very easy to mount in the moon clip but the reloads are a bit of a bear to get them to seat

One round in particular had what looked like a comet spinning off to the side and was wondering if that was some remnant walnut shell from the vibratory cleaner?

It's fun to shoot your own!

Smokeless powders react to pressure. Without a cartrige to contain it smokeless powder just burns.

Some powders react differently than others, ie 6gr of a powder probably won't give twice the pressure as 3gr given the same case volume and the difference will vary from powder to powder.

Not sure if I'm making sense...

So, if I notice quite a bit of kick difference in .2 grains, taht means there is still pressure build prior to the bullet release? Are you saying that at some magic point, the increase in grains yields no real pressure increase (and I would presume out of the case burning -ie lots of flash). Just trying to connect the dots.

If you noticed a true, significant difference in 2/10 of 1/7000 of a pound of powder, you might be close to the limit for your piece. Are you real sure about this? Could it have been towards the end of your session when you were getting tired from the recoil? I've shot most of the common rounds from .380 to .44 magnum and I don't think I could tell the difference. I will confess to being insensitive, but only about some things. Recoil usually is not one of them.

I don't think I noticed a difference in the weight of the round difference (2/10 of 1/7000 of a pound of powder) - but I'd swear about increased recoil

I did take a vid of the session. Although the usefulness of the vid is nil (camera angle should have been wider to actually include the gun) - maybe you can detect the variation in loudness....? Ok, I'm going to have to go back to the range and prove it to myself again, I don't detect any difference in this "edge of the seat - gripping videography" presented here.
The first vid is of a moon clip of factory ammo (8 shots) followed by 6.6 grain (8 shots) then 6.8 grain (8 shots). Two shots in the third moon clip of rounds, embers are seen down range after the shot
The second vid has a mix in the moon clip:
factory,6.6,6.8,factory,6.6,6.8
For whatever its worth....certainly not a discussion on being able to hit the broad side of a barn or not.
