Help!

My EMF 92 blows back a nasty powder residue with each shot. I've been cryin' about it since yesterday. Actually I took my first shot without my safety glasses on and it feels like weld slag on my retina. Anyway, the gas is going past the casing and the ejector configuration throws it right in my face. Anybody else experience this? I'm new to reloading and I guess I'm sizing them too small which lets gas around the shell -or- my load isn't powerfull enough to expand the case and seal it off.

Any suggestions?

thanks

I'm gonna post this under lever actions and reloading also.

What's it chambered for? If it's a straight wall case, try just "necksizing" yer brass to cut down on blowback. Also stick with a heavy bullet weight to help give yer powder charge a chance to expand the case into chamber walls before the slug moves out. And use a stout enuff load, not a "gamer" charge of powder. Finally, and I have no idea why this works but it does, put a card wad under the slug before you seat it.

Howdy,

The crimp is important. Also bullet weight for the caliber is a factor.

Adios,

Howdy:

I found a strudy crimp helped a lot. I still get blowback every now and then. To be condid, I think that is why they make safety glasses - no saracasm intended...it just seems to stop the unexpected poof in the eye and the day or two of "ouch" that goes with it. :grin:

You may not be using a strong enough load to seal the front of the case to the chamber walls. If using a .45 Colt use 255 gr bullet with 8 gr Unique. One other thing you might do is heavily inside neck chamfer the brass. This helps seal the case to the chamber. I use the .44 mAG 1892 EMF Blued Hartford Carbine with very little gas blowby and I use BP exclusively. There is a big difference in blowby, when I inside neck chamfer.
