My 6BR in 300yd F-class. Which bullet?

I have a newer 26” Shilen 6BR no turn neck barrel with a 1:7.5 twist that I’m using for strictly 300yd F-class. I’ve been using 107 SMKs and getting decent accuracy, but thinking maybe lighter would be better at this closer range? Your thoughts please?
Right now I’m using Rem71/2 primers, Lapua brass, 29.5 Varget, 15k off the lands. Thanks!
90 gn Berger BT 26" barrel 500 yards, 31 gn Varget EDIT: 1/8 twist Bartlein.
BTW my first ever match over 300 meters. Happy? Yes, more than happy!
I'll be using this load and gun for the 200/300 yard state championship

Do you mean the 200/300 UBR Nationals...at Somerset in July? That match is why I'm toying with a similar setup...a 10 twist 6 Grendel with either 87 or 90gr bullets. After last Saturday, I'm convinced it's working pretty well now, after a little tuning and load work. It's REALLL close.

Yes, Nationals, you know KY is as big as the nats! LOL you know its not just a Texas thing!
 
Im very surprised more people arent using lighter 95gn bullets for 300y. If you check the ballistics of lighter 95gn loads at the higher velocity possible, the wind drift is about the same as 105s at 300, but you have the advantage of lower recoil and less hold/bag set up sensitive.
Recently shot a club match using 95 gr Berger BT in my 6BR. I was very pleased with the results at 300 yds. Actually shot targets at 100, 200 & 300 yds. Did that all with the same bullet and load. 300 yds was a real challenge with really bad mirage and some wind. 100 & 200 were great. If I had my choice however, I would have preferred to use 108s at 300. Had some loaded but failed to bring with me to the match.
 
A bit late, but I'll throw in my 2 cents for people searching. I would use something in the 103-107 weight range. You can get excellent accuracy, and wind still matters a lot at 300. I don't think the slight accuracy advantage (potentially - if you've got a slower optimized twist) of the 90s is worth the little bit of wind you give up, but that's a personal choice.

There are several customs available in the 103-105 range, the Berger 105s, and Sierra 107s. Are all good choices in my experience.
