Thread: Trying something, Eric Cortina method of load development

@zimmer had a good watch, very informative. Going to struggle with out an accurate seating die, two calibres on thier way as I speak though. This time I also watched Cortina's video. Should have done that in the first place. @dannyb case lube on the projectile makes a huge difference. Measured jam with 5 different projectiles 3 times each one. Max variation of 3 thou. Pleasantly surprised. As soon as my flash seating dies arrive I'll be into it. Rifle already shoots two loads MOA but I've got two boxes of other projectiles that shoot OK but not brilliantly. I'll try and tune them. Got pleant of 2209. Going to do the load ladder, chrono it, then back them off 20 thou from jam and work backwards. I use 760 with the two winners but I'm sure 2209 will do the job.
