Welcome to the world of HANDLOADING. It can be fun and frustrating at the same time. I would like to give you one word of caution using the TSX. Barnes and others always recommend you start with their starting load. This is a good practice to begin with. I usually exceed max loads listed in manuals with my rifles and back down 1 full grain if I run into pressure signs. I recently acquired a 30-06 that my Grandad owned for over 20 years. He didn't hunt much and said he fired less than 3 boxes of ammo through the rifle. I like Barnes bullets and happend to have a friend give me a box of the 180 gr. TSX. I seated the bullets .050 off the lands as Barnes suggests. When using the Barnes bullets you can go from .070-.030 off the lands but don't get closer than .030. To make a long story short I was .5 gr. under max load when I started seeing pressure signs. So always start at the bottom and work up. I also use the 140 TSX in my 280 Remington. I can only exceed max load for the Barnes X by .5 gr. or I start having too much case head expansion. So please especially when new to something exercise caution!!! Good luck and I hope you enjoy reloading (especially when you get your first sub .5" group) as much as I do. Another note for the Barnes bullets is that you can often start at .050 off the lands and if your accuracy is terrible you can improve it by moving the bullet fore & aft towards the lands.
