5 Great Powder
Posted by Fred Honeyager on Dec 29th 2022
I bought this powder for 38 Super and 9mm as I could not find my long time favorite Hodgdon 700X locally so I thought I would try this as I have heard a lot about it. Works great in 9mm and 38Super with a 125gr. LSWC gives great performance and accuracy with both calibers meters very well and burns extremely clean. I managed to get my hands on 200 Large Pistol primers so I tried it in my Springfield V-16 Long Slide and my Springfield Range Officer Elite all I can say is that this is a great powder in 45 auto, it makes it very accurate and in my opinion makes the 45 auto capable of all it has to give. This may become my favorite powder for this caliber and that says a lot as 700X has been a powder I have been using for 27 years. Also works extremely well in 40 S&W.

This is easily my favorite powder for 9mm. Good velocity and very low ES and SD. I tried it for 38 special as well with less success. For 9mm, I don't know of a better powder. It also meters very consistently in all of my powder droppers.
