Looking for advice. I am going to start working up a load for a Tikka I bought for my son for X-Mas. I exclusively use Barnes for my hunting bullets and love them. I have never loaded for a Creedmoor but have plenty experience with other calibers. When I load the 100gr TTSX to 2.700" COAL the forward groove in the bullet is completely exposed, this is a new Hornady Case and is trimmed to 1.920. I have never seen this on any other caliber. Is this normal for this combo or is something totally off?
