That’s about identical to the build/purpose I had in mind. What do you figure your velocities look like, and how do those TTSX’s expand at “long” range? Can’t imagine they’re moving too fast when they hit; that’s been what’s keeping me from trying them in .308I got a lot of experience with 358 Win as well. I have a rebarreled Savage with an 18" Shilen barrel. It is a great brush gun that I use for bear, but I am currently working on lightening it up and taking it out for mule deer and elk. I handload 225 grain TSX for bear and am working up a load with 200 gr TTSX for elk and deer. It is a great round. My 200 grain load will have more energy at the muzzle out of an 18" barrel than a 200 grain 30-06 out of a 24 inch barrel. You can hunt anything in North America with it.

Work up to that slowly. That’s gonna be a hot round. The TTSX bullets act like a lot heavier/longer than they are. You certainly can’t use traditional load data for a 200 gr bullet.I havent finished load development yet but I think I'll get just under 2600 FPS with the 200 TTSX and 52 grains of TAC in my 18" barrel. There is another member on here that I got load data from to work up a load for my rifle. That should get me out to 400 yards pretty easily at Rocky Mountain altitudes with plenty of velocity for expansion on elk and deer. Haven't killed anything with that bullet or at range with it, but I plan on taking it for mule deer next year in Utah. It should flatten any buck I decide to shoot.

Sounds like you are on top of it. I load 50 gr of TAC. I saw pressure at 51 gr and the 180 ttsx but that’s out of a custom gun with a tight chamber and minimal freebore. Accuracy was best in between 49.5 and 50gr.
I also loaded H4895 with fabulous accuracy but I had a hard time getting decent speed without a pretty compressed load. I wanted some speed given the copper bullet.
