I am nearly complete with my 300 PRC build I am curious if anyone has any info as far as load data & what this cartridge seems to like bullet, powder, primer & etc.
Rifle is a McMillan A-3 edge stock, 26" Krieger 1 in 10 twist barrel, Defiance deviant ultra light action, Huskemaw 5-30x56 scope, triggertech trigger & stinger worx emporer suppressor

With 1-10 you might be a little handicapped on shooting the heavier bullets like the 225's and up. That being said I bet Berger 215's and and 74.5 to 76 grains of RL26 would be a good start. Start lower and work up. Also, double check with your suppressor manufacturer to see if they have a specified limit of grains you can run on your can.

the suppressor should be ok its rated for full auto on a 300 win mag with as small as an 18" barrel
 
I have only shot 215s in mine, also a 10 twist. I also have 181 hammers and will be picking up some 210 vid. The 215s shoot good, still early on this barrel and no hard load dev yet, still on virgin brass

Im shooting rl26 in ADG brass. Mine prefers 215M in my load but cci 250s still shoot very well

How much RL26 with the 215 hybrid? What length barrel and what kind of velocity are you seeing?
 
2900 FPS 21" barrel pm me for charge weight but I just called Berger and used their data to find pressure and then backed it down 2 grains from max. It went over 3k before pressure

21"! That seems so short. I have heard that the bigger magnums are hard to tune for with short barrels but I have zero experience with it.
 
has anyone tried the factory Hornady 300 PRC ammo the precision hunter 143 ELDX shoots pretty good out of my Howa 6.5 prc?
