You're thinking good Pharm.
Btw....100 yd testing might not be real ideal for those longer bullets..... sometimes they settle down alot as they go down range. Years ago I almost passed up 180 grain Barnes load for my 300 Weatherby this was in the pre TSX days. Best group I could get was about 1.5 inches at 100 yards and I was looking for more until one day just for Giggles I tested it at 300 and it was easy under 3 inches.
