HillBilly,
Just got home after an evening at the range trying the 120TTSX with your recommended powder charge. Started @ 59g of H4350 and shot 4 on a clean barrel. Grouped about an inch. No pressure signs so I moved up to 60g and shot 3 that grouped 1 1/2". Again no pressure so I moved up to 60.5 and fired 2 in the same hole and again no pressure. Moved up to the last lot I prepped @ 61g of H4350 (your load) and fired 3 more that impacted in and around the previous 2. No pressure signs and the 5 shot string measured .383".
I did not set up the Chrony but will have that data the next time. Really won't make any difference cause when I stumble onto one that is as accurate as this load is horsepower is no longer much of a factor. Thanks for the recommendation!!
Dave
