OK guys, PLEASE no one get their dander up and start throwing stones my way. I'm in this game to hopefully have good results just as I suspect most of you are.
However, a number of times when the powder coating subject came up I posted that I desired to see side by side - lubed /powder coated - accuracy tests with my interest being the best accuracy possible.
Either no one has made such tests or simply didn't wish to post their results.
I'm not - hear me now - not posting to dissuade anyone from powder coating if that is their preference, I just wanted to see side by side accuracy results as I have been sizing/lubing for too many years just to jump into another process without clear gains expected.
So, recently I picked up a February - March 2018 Handloader Magazine in which was published a hands on article by John Haviland on the subject of powder coating.
In this article he explores different process and then tests for accuracy a 7mm/08 with a 147gr RCBS bullet along with a 30/30 and a .45acp.
Of those three cartridges and firearms, the 7/08 gave better accuracy with the sized and lubed bullets, the 30/30 gave a slight edge to the powder coated bullets and the .45acp gave a clear advantage to the sized and lubed bullets.
AGAIM, Please don't start throwing those stones my way, but this is the first time I have read anything close to answering my questions about the accuracy potential with powder coated bullets.
Anyway, being the Ol'Coot that I am, and having sized and lube thousands of cast bullets for many years, guess I'll just stay where I am.
Yep some advantages to this new process with the cool colors, lack of messy lube etc. but considering the additional steps required to complete the process and the fact that I'm well set up for the old size and lube process, guess I'll just ride it out until/unless I see a clear accuracy advantage shown by side by side tests. Same bullets, same firearm etc.
I'll repeat, don't get your collective danders up as I'm criticizing or trying to say to anyone not to use the powder coating process, but finally I have read some of the info I'd hoped to read, a side by side - although limited - comparison.
