Your process is good with one exception. If you load with coarse powders, you could find yourself with a squib load in one case and a near double charge in the next. I had this happen to me recently with H4895. Yes, this is a rifle powder. But the risk is still there. The powder bridged in my Uniflow and only dropped a few granules into the pan. I thought that it might have bridged on the powder side and not filled the drum. But I put the pan under the measure and cycled it again and got damn near a double charge. So, the powder was bridged in the spout portion of the Uniflow.
I have a different method to assure no double charges. I have a dowel that gets a line drawn on it for the correct load in the case. I then charge all the cases. With the cases full, I go around with the stick and check the powder assuring no double charges.
At our club, we had two double charges, both in Springfields, thank God. One was me. My standard load is 17.5 gr of 2400. So, there was 35 gr of 2400 in that case. It was much louder and kicked like a mule. I could not open the gun. We had to pound the bolt open with a piece of firewood and a hatchet. The primer fell out on the bench. The primer pocket in the case was a good 20% bigger. The bolt face was brass plated.
The other was a .308 Criterior rebarrelled 03. This one was more violent. Blew the floorplate out of the rifle and jet blasted the spotter sitting next to him out the gas relief port.
Both rifles suffered zero effects (other than my brass plated bolt face). I think mine even shoots a tad better.
I always stick checked my cases. But I got complacent. I skipped the stick check. Afterall, I've been reloading for close to 60 years. Bullshit!! Had that been a lower grade receiver (I read that 03's were proof tested to over 100,000 psi) I might be called Blinky, now.
