Best get a neck crimper to as you do not want the projies to move under recoil, I crimp all mine as the last thing you need in a speed shoot is a projie in the case and an action full of powder. Besides keeping things in the case you know that the neck tension is all the same for each round, yes I know we are not F classing here but it is just one variable I eliminate. I use Fed - 210 primers and they work well. Hornady 150 Spire points work really well apart from being a FB they are also .312" good accuracy up to 350m ~ 400m I used AR - 2209 I found 2208 a bit sharp welcome to the world of Lee Enfields and as had been said before prepare for them to multiply as they grow on you
