? 7-30 waters and 135 grain cast Boolit

[flipajig]

Hey y'all is anyone out there loading the 7-30 with any of these powders
2400, Unique , IMR 4227 with these powder shortages these are the ones that I have most of on hand. I'm wanting to shoot these out of a 15" tender.

Never tried 2400, but I have the other 2 you mention with the Lyman 287346...

Unfortunately, I never really experimented much with Unique or 4227 as the accuracy was not good at all from a Super 14"...

I had the best accuracy with H-335, WC-844 and for extremely light loads, Trail Boss...

Good-luck...BCB

I shoot a 22" contender carbine in 7x30 Waters. I use 120Horn sp and 130 Speer btsp Jwords with 748 and H335. I have not attempted cast nor any powder as fast as in your question.
