Finally taking my first steps into rifle reloading. Trying to work up a load with a Hornady 75gr bullet for my AR. I've been reloading pistols for about a year, but tend to run those at low pressure for the caliber. Now I'm looking for a load to shoot 400yd and don't want to have to fight the wind more than I have to, so just loading enough powder to cycle the action won't cut it anymore.
Anyways, following book recipes but the primers are looking a bit flattened to me in comparison to what I'm used to... The load is Federal brass, CCI SR primer, Hornady 75gr BTHP seated to 2.26" and from 23.5-25.0gr of Varget, working up 0.5gr at a time from left to right. I do see a bit of cratering on the 25.0gr load, but they all have squared off the shoulder of the primer compared to before firing, is this OK/how much is OK? Unfortunately, had chrono problems so no velocity data... I also attached a pic of how factory Hornady 75gr TAP FPD leaves the primers in the same rifle for comparison.
