Are you having issues with them then or just looking for feed back also?
I’ve worked up loads for a few over the last few years no where near as many as yourself, Mike etc just mine, colleagues & range rifles. Some have needed a minor tweak after a number of rounds be it a very minor charge or seating alteration.
This ECM barrel is being used with one of the dirty powders & the loads grouped quite well during the work up to the final load. Not one of them would have failed the accuracy guarantee most rifles come with bog standard. I’ve always favoured accuracy over speed & the last group I shot I stopped at as five in a single circle is normally more than most are happy with. This is for target though so when our range wheelchair access is finished in a few weeks

I’ll see if seating will offer anything further. Why not?
I use the same cleaning products as I’ve a couple of large bottles etc from the shows & this cleans up pretty sharpish over my others.
I’ve fire formed 300 cases, using three powders & different primer combinations. The fired/resized cases are the same as the load found during fire forming so more than happy so far.
I’ll be honest, first time fire forming. Weren’t keen on it or looking forward to it at all, but it went smoothly & it went well, The cherry on the cake was finding the load during forming & it being repeated aftera clean, resize/reloading.
I’ll chrono the final load for the Kestrel.
Have you had any issues then
