Stainless steel media is the best!

I did the experiment!!!

So does that brass that's all shiney/purdy shoot better?:nest:

I was wondering that myself, so i did the experiment... I loaded 10 rounds of winchester 9mm brass cleaned with SS pins and 10 rounds of winchester 9mm brass cleaned the corn cob way... I only chronied them.. did not look at accuracy because i wanted to see if there was any difference in powder burn and velocity.

Short story..

NO REAL DIFFERENCE in Velocities.

Only difference was the amount of variation in Velocity between round 1 and 10...

SS PIN.. lower Variation in Velocity (cant remember exact data but it was around 5 fps)

Corn Cob.. larger Variation in Velocity.. cant remember exact data but it was around 11 fps or about double)


All powder charges and projectiles were weighed by hand to make things as equal as possible.. Although i am a scientist.. this study was hardly SCIENTIFIC Just something i wanted to do out of curiosity. I only did this ONCE. Probably should repeat 10 times.. but i have too much fun shooting..

Cheers

The stainless tumbling media does NOT peen the brass, does NOT bend/ruin case mouths, does NOT wear out over time and is the BEST cleaning method out there. If you don't want to wait for the brass to air dry, throw them in the oven at 300F for 20mins or so, voila!

I will never use another method to clean brass
 
I dry mine several ways..
Heating registers, both forced air and radiant
Air compressor, then hit them with a heat gun/blow dryer
Oven
Stick them on top of air conditioner in the summer
Microbre and let them air dry, old used cartridge holders work well the hold the cases upside down and dry.

Hey where would a guy pick up some of this SS media? I really don't want to order from the states.

Order from Stainless Tumbling Media, no cheaper here and he is the one that went through the work to get this system to work. He is a small operation and could use our support up here in Canada. They also have the right size media so you don't wreck any brass.

I have a question for you guys using the stainless steel media, have you ever tried using the Lyman plastic mesh bags in the tumbler? If you have how well do they work.

I have a Lyman vibrator type and I use the plastic mesh bags to keep head stamps/lots and different sizes of brass separate and it makes it easier for me when emptying it out to keep it all sorted.

I am leaning towards getting a SS setup myself when I have the extra $ but I would like to keep the brass together so I know which brass goes into which case. I would hate to have to run small amounts in the tumbler just to keep everything straight.

It is ... and take a look at the FAQ section of his site. One piece of advice, much as I hated it, was to throw out the pieces that stuck in the flash holes or neck. You toss them, they don't get stuck again (and again and ... well .. you get the picture).

Actually, Trevor Dickerson (STM.com) copied the idea from Mark & Terry at Sniperhide. Nothing wrong with STM.com, they bundle everything up and ship to Canada which is very convenient. However, there are cheaper (arguably better) suppliers out there. I got my media from Mark (5lbs) for $55 to my door and my Thumler (model B) from Cabelas (USA) for $196 to my door. The reason I went with Mark is his pins are magnetic which makes for ease of cleanup, apparently (I can't confirm) STM.com media is not magnetic. FYI Lemishine is $4 @ Canadiantire.

Wouldnt magnetic pins make them have an iron content which would make thier rockwell higher resulting in more peening effect on brass as opposed to stainless pins (I doubt its 400 grade stainless for a pin, but you never know)
 
Cinch is right. Terry and Mark are the ones who startedthis whole ss media craze. I first about it there myself. And yes, the media needs to be magnetic, but only for ease of cleanup.
 
Looked on a metal list, 303 and 304 becomes slight magnetic when worked so maybe the friction during tumbling is magnetizing it. If its either of these grades though. Is there a specific source for these pins? McMaster carr doesnt seem to had the diameter of 3/64s is that correct?
