So, I am slowly working through cleaning the collection of brass I have accumulated over the last year. Yesterday, I tumbled roughly 150 cases of a mix of 38 Special and 357 Magnum, but placed 4 quarters of a used dryer sheet in the mix this time. I am quite please with the results! The outside of the cases looked a little cleaner than the batch without the dryer sheets, and the insides appeared free of any buildup. I think, for now, I will consider this to be good for my purposes, but I'll reevaluate as time goes on.
Perhaps I will look into more thorough cleaning methods if I get into more precision shooting. Right now, I'm wanting to reload to have ammo to have fun with at the range, so precision accuracy is not on my radar at this time.
I appreciate the comments! I am enjoying learning about the different cleaning methods, and I really appreciate all of the advice!
As a new reloader, you all will probably see future posts from me asking more questions on various topics!
