As the title suggests, I am curious to hear about peoples experience with 69gr Nosler BTHP loaded with Ramshot Tac, particularly out of a 5.56 chamber.

In the past I have had a lot of cases not fully seal my chamber when loading to max 223 specs, resulting in carbon on the sidewalls of my cases. So I am going to be cooking all my loads at the upper end of 5.56 loads so long as accuracy and pressure signs are permitting.


Planning on shooting ladder loads in .5 increments from 23gr of tac to 25.5, using CCI450 primers seated to mag length. Once I find the best accuracy load with no pressure signs or non fully sealing signs in that range, I will tinker with things like seating depth.
