What powder will have the least blowback for 5" 1911 45 ACP

Using Octane 45 HD and 230 grain round nose jacketed. My blowback is real bad using Power Pistol and Win. 231. Baffles are ALL correctly lined up . Does anyone have a powder suggestion? Would Bullseye have less blowback because it burns fast?

Try a VV powder if you can find one. I switched to N320 in my 9mm and it's much cleaner, much less junk in my face.

So I'm having the same issue with AA #5. I've had a few flame outs as well. (un burned powder igniting in the can).

I'm thinking of trying Titegroup if I can find any.

I've been running 700-X with a 230 grain FMJ and so far the blowback has been very minimum.

What is your charge weight on the WW231? I run that all the time and never really noticed the problem.

Titegroup is my go to for 9 and 45.

In my experience, lighter loads seem dirtier than a more moderate or stout load.

+1 for N320 if it works for 45ACP. I also run it in 9mm and it's mad cleaner than AA7, and a bit cleaner than CFE-P.

N320 runs just fine in 45.

I am using a 231 charge weight of 5.4 gr. The blowback for 700x and bullseye is very minimal but my uniflow with case activation on my piggyback2 clogs, so I have been testing Tightgroup. 4.7 GR. of tight group seems ok, but still has blowback. Has anyone tried VIT. 310, and if so how is blowback? Would I have less blowback if I used lighter bullets?

Bullseye is not the answer. 700x has the least blowback so far and Tightgroup is 2nd best for blowback. Its to bad 700x meters like cornflakes but I will still use it because it has the least blowback from what I have tested so far. I had to add a second spring on the opposite side of my RCBS Uniflow with the new case activation system so that I can use 700x in it smoothly.

Titegroup works pretty well in my 45s with the Osprey and Octane.

I found out that the Redding duel ring carbide sizer for 45 ACP actually helped a lot to reduce blowback. I am going to try the Rugged suppressors pistons because they will work with the octane and don't have the slot cuts for gas to come back at me.

Outstanding. I was thinking about this the other day but didn't know about the Redding die. Thanks for posting

edit: HOLY CRAP they're $100 :cry:
better extend brass life a good amount at that price
