I understand this topic has been brought up before but ive already eliminated most of the comments people have suggested, Loading 147 gr polymer heads with N320 3.3 gr which used to work flawlessly in an M&P Pro. I now am getting about 1/5 rounds tumbling in the Shadow 2. Crimp is not removing any polymer off the heads. Tried reducing the powder. can anyone help me with this as i am stuck. Note: i would like to stick to 147 gr heads
Hello Everyone, I just got done doing a informal Non-Scientific experiment to see what would get me the best results using the Stainless Steel Pin Method of cleaning Brass and Walnut/Corncob. I used Range brass , mostly 9mm fir my test. And I did not I first started with Corn Cob and Walnut combinations using Nufinish and all the other similar products out there. I was able to get to a 80 Percent of a new finish using 50/50 split of Walnut and Corncob Nu-Finish car wax for 2 Hours. The insides where not real Clean. But that does not mater to me very much. Next I tried my new Frankford Arsenal wet Tumbler with10lbs of Pins and 8 Lbs of brass. Using Dawn and Lemonshine and let it go for 1.5 hours. That came out at about 90 percent clean. Then for my last comparison I used the Cleaning solution that came with the Tumbler for 1.5 hours.. WOW>>>>> That came out like new at 100 percent. So I tried it again using that solution on some really bad brass that was 45cal. Again I compared it to some brand new Starline Brass. This is what I'm going with. So I know that other people will other results and this is not the "do all" for everyone but it works well for me. If you want super Clean/Shiny Brass the Wet/Stainless Steel Pin method is most probably your best bet. But just my opinion of course. Jan
I use a rotary timber with stainless steel pins to tumble. I add a little Dawn soap, and a little Lemi-Shine to the water. I generally let the tumbler go for about 4 hours. Yesterday, I started the tumbler, and lost track of time and the casings tumbled for about 5 1/2 hours. The color of the casings were almost copper in compared to the 4 hour tumbled casings which were brass colored. My questions are: 1) what caused the color change? 2) are these copper colored brass cases still usable? I've attached a picture to show the difference.
