I’m looking at building my first semi custom rifle. At the moment I’m thinking on using a tikka t3x action, carbon six barrel prefit barrel and undecided on the stock. The purpose of this rifle will be occasional long range target shooting and mountain hunting. I am wanting to use my suppressor and keep barrel length between 20-21 inches. I’m thinking 300wsm using possibly Berger 200.20x bullets, as I will be hand loading for this rig. My question is for those of you that have built custom rifles, what would be y’all’s recommendation on carbon vs steel barrel? Do I just need to find a good gunsmith to put on the barrel. I’m really wanting this rifle to be very Capable out to 1000 yards. Opinions on long action vs short action tikka? Open to any and all opinions at this point. Thanks
