I’ve had fun reloading an old box of 100g Hornady SP in my 270 Win. I just bought a bag of 110 TSX in .277 and want to develop a 400yd laser. Barnes lists H100v as one of the recommended slower burn powders and I have a sister powder (staball). Has anyone got experience to share with the lighter Barnes in a 270 or 6.8 platform?
