Thread: T3 300winmag loads

Hi guys, I have a mate with a Tikka T3 in 300winmag who Im going to do some load development for.
Was looking at using a 180gr Speer BTSP fitted to mag length for the close stuff and perhaps single feeding the 208 Amax for long range.
Hopefully both pills will perform with the same powder?
Just wondering if anyone on here is using a similar setup and/or can offer any advice with regards to this calibre, setup?
Any info much appreciated. Cheers
