Thank you Steve.
The one really neat thing about the Tac powder is that it has much lower pressure vs the FPS it produces than other powders do. For that reason, the higher to max loads of Tac don't worry me as much when it comes to high pressure.
It's a really neat powder if you find a load that shoots well in your rifle with it.
I have tried the Tac with the 69's, but not the 62's. I better get on the ball.
I just got a Crony with the printer, I'm really looking forward to the data that I get from it.
Having a cronograph is almost a necessity when working up loads and figuring bullet drop.
You can find out a lot about your loads shooting over the screens.
Very good info. I have not seen the BC numbers on the SS109's, they just look longer than most and I'm not sure if the bearing area is longer or just the ojive. I'm thinking it's just a longer ojive.
