Now that the weather's getting bearable, I'm doing my first test ladders for a stainless steel Tikka CTR in .260 Remington in a Manners stock. I'm loading Berger 120 gr. bullets over 47.8 to 50.3 gr. 4831SC (that's a pretty full case!), Berger 130 gr. bullets over 44.5 to 46.9 gr 4831SC and 139 gr. Lapua Scennar over 43.6 to 46.0 gr. 4831SC. I've colored my test rounds (my granddaughters covet my markers) in the hope that I'll be able to identify which charge weights hit where. I'll post results of the testing when I can get out to the range.
