Spinning up a 1-8" 6br barrel to try shooting some matches this year. I've got 500-ish 105 vld's, but will need more bullets soon enough. I'm pretty new to PRS style shooting, so bullet choice won't be a limiting factor in my performance for while, but would love to hear what has worked for others. Rifle is a Tikka in a Whiskey 3, with a 5-20 Razor Gen 1. Been shooting 139 scenars out of 6.5 creed up until now.

The twist rate recommendation for the berger 105 hybrid is 1:7.5. The Hornaday ATips are 1:7.7.
Might consider the 115 dtac as well.
So you might want to consider having the twist rate at 7.5 to shoot all the bullets that have been mentioned here.

My 2 cents, all future 6mm barrels for me will be 7.25 twist. 7.5 has worked... but in the cold winter matches I have noticed my stability rating was under a 1.5 and that it could impact my elevation predictions. While this hasn't been seen in my 6mm's performance I have had it impact my 223's performance, so it is a real concern. That said, back when the 105 Hybrid was new to the market my 1:8 twist would not group well if the temps were 50 degrees or cooler at my altitude and a second 1:8 barrel would not group them well at all regardless of temperature. The 1:7.25 twist in my data modeling down to near 0 degrees and 500 feet ASL will work well with all bullets currently available to the 6mm excluding solids. My coldest match so far started at -3 degrees for the day.
Not only that, but the 107 SMK has been available through bullet droughts when Berger was unobtanium unless you were sponsored. I used to shoot only Bergers, and on one of the price hikes I got pissed and switched to Sierra. I always try to buy components in bulk, but before Covid I got a line on a crazy deal for a massive amount, and basically bought a lifetime supply of the 107s.
Once you pick a bullet and go through all the trouble of setting the gun up to shoot a combination that's money, I find I'm loath to change anything lest I have to go back and do it all over from the beginning. Some people love load development and finding what shoots the straightest. I used to like doing it, but now I find it to be a hassle and would rather keep doing what is working than going back to the drawing board.
