Thread: what weights?

so my new tikka t3 308 loves 150gr sst hornady superperformance, but i refuse to pay $73 a box of 20! so the brass length is 51mm oal is 69.7 weight 24grams. got a decent amount of winchester brass so going to uses this, trimmed it down to 51mm and got it cleanish, got the same projectiles, now the question what powder? got a stock of 2206h which i would like to use but unsure as to what weights to start trying and what intervals to use.

realise that it is different for every rifle but what intervals do you guys use? according to ADI handbook 41gn lowest and 43.5 the highest last time i was reloading 2206h in a 308 case, i could only get 42.5 as a full case. so 0.5 grain intervals? 0.2 would make a lot of choices but at 0.5 could i miss the sweet spot?
