1-9t in actuality covers everything you'll realistically be able to and want to shoot in the cartridge; 180-230 grain. Quite frankly anything north of 230 is better served in a Norma Magnum. Additionally, in the big 30's a fast twist may possibly limit you to the heavy stuff, 230+, as there are plenty of guys who have their 1-8's turn the lighter stuff into dust mid flight as jackets separate. I have 230 A Tips, they are plenty for out to a mile. My understanding there as well is that you should take the speed of < 230 grain projectiles since at most distances you will not really even be able to take advantage of the added BC from the 250. Norma makes sense for the 250 since you can get it moving faster. Hornady made there OTC Match load based around a 225 grain for a reason. It's a balance of speed and BC at a given distance. I would actually go as for to say that inside of, say, 1000 yards you are actually hindering yourself from a technical / performance standpoint taking the 250 over the 230. There are a couple 300 PRC threads on here that are really good reads on all this, here is one:
