I've had some extraction problems with my STI DVC open gun for a while. I played around with the stock extractor and also installed a Aftec extractor and followed all the instructions but still have some intermittent extraction issues. So I am wonder if ammot power factor or powder burn rate can have any effect on this. Any ideas ?
I'm shooting a DVC open gun chambered in 38SC using Starline brass, Montana Gold 124g JHP and 7.5g Winchester Autocomp powder for a power factor of approx. 176.
Would this high of a power factor cause extraction problems ?
Is the burn rate of WAC too fast ? Should I try a slower burn rate powder like maybe VV3n38 ?
Thanks in advance for your help
