Re: 7mm-08 and 140gr. TTSX?
Going by my reloading manuals, it seems the best velocity for the 7mm-08 with 140gr. rounds is 51gr. of RL-19, usually from my experience, monolithic bullets reach their max at around 1gr. below lead bullets, so it would seem to me that max for the TTSX would be 50gr. of RL-19 and 46.5gr. of RL-17.
These two powders are all I'm working with at the moment, though I do plan on getting some H4350 when the shop in my town stocks it and I can get some before they run out (usually runs out within two days of receiving the shipment here), nothing wrong with reloader powders here though, I live in Cali with mild temperature swings, so I don't really experience the negatives of temp sensitive powders, and reloader powders offer the best velocity and great accuracy.
