Hi Tone and others
I was just looking up your load,i see its just at the starting load for the 55gr bullet.
Id just like to add that in my experience loading for my .223 the starting load like the max load is not always the most accurate.My advice to you would be to move up gradually and of course never exceed the max load with your bullet weight.
I use sierra blitzking bullets 50gr and 55gr with Varget powder only because it had fairly good load data for the range of bullet weights i was going to use.
Like the previous post on where you can expect your shots to land on target at 100yds
