Did this video help you?

urbanmerc1: Why do you trim that way vs trimming to the datum point on the shoulder. I would think trimming to an overall length would be less consistent. Thanks Rex great video series keep em coming brother. 

batmandeltaforce: If you want consistency you don't reload to begin with.

SA Bjork: Great vid, Consistency is important. I found that Ultra Sonic cleaning get the primer pockets, and case internals, very clean without the manual labor. And secondly, you can also chuck the Lee cutter/trimmer into a drill press and vise the locking shell holder into a drill vise where you are spinning the cutter and not the case. This works for large volumes and saves your fingers from blisters and cramps. Good work.

tigersire: Hey buddy. Get your stuff in the proper specs.

Nunya Bizness: Who is this fellow? Firearm savvy, very articulate, shoots extremely well, and kinda sorta - pronunciation wise, even sounds like the Nuge. Alright Rex what's the deal with that, hair, sideburns, is Ted Nugent your pops? That shirt sorta seals the deal. All seriousness now, that was well done on the reload case prep tutorial. 

Villamor78: To make my reloading life easier, I use a stainless steel tumbler. Cases becomes spotless clean inside and out. It also deburs and chamfers the primer pocket and neck. The Little Crow Gunworks trimmer is also a great tool for trimming. Plug it to a power drill and you trim hundreds of cases in an hour with consistent results.

PaleHearse: Only thing that might also bear mentioning (not an expert here..just a process engineer who's interested in reloading) is that the reason those cases get stretched is that the material is moved up the case. Removing the excess length repeatedly will also mean that that material came from lower down the neck. Measuring the case thickness at the neck will also be important to make sure it's not too thin. You should probably do this when you measure the case to make sure you don't get all the way to the end after polishing and find the case won't pass.

Marc Bolger: What's your take on "Neck Turning" I need to learn this and I am also wondering if it is something we really need to do? When it is usually needed etc.. There is no end to what I don't know. I have read almost half of this book titled "Metallic cartridge Hand Loading" by Mic McPherson. In this book I learned to polish my neck after I have chamfered and de-burred to remove the rough edge of the cutting tool used by lacing fine steel wool around the brush. Run that through it a bit to make it smooth like glass for seating my bullet. I also wash my brass with a sonic washer before I de-cap and neck size and after. I guess I do it before so when I run my die through my brass it seems cleaner on my die's machine surface being a bit less friction and smoother sizing press action. "?"

TheCharillz23: thanks so much rex. I love you videos. for everyone out there check out the steel media works great. made my own tumbler for 40 bucks and cleans better than any media i've come across. also i buy box ammo for brass shoot it and reload it. mainly because i dont get shoot more than 300 more than 3 times a year=(

Bill Lynch: I do the samething as villanor78 best media ever. Some water lemi shine and done. And I use little crows finest trimmer as well for all my calibers. *\- .0010 trim length 

Jonno2summit: I tumble my brass twice. First tumble is the first step just to save wear-and-tear on my dies - just an hour. Then I de-prime/resize. For range brass I run the heads lightly over a metal file to take down the high spots and make my brass of various mfg more uniform, then I run a primer pocket reamer in there. Often the reamer will take out more material on one side. That is when I know I've just made my primer pockets more linear/straight with the centerline of the casing. For those who tumble in organic media like corn or walnut, you can dribble some Hoppes #9 in there, and Brasso brass polish to clean and polish. Having compressed air on hand to blow out casings with high pressure really helps to make things clean.

Ted Bundy: Awesome. Thanks for this video. Very useful information. You do sound like Uncle Ted!

Rudy Mendoza: Where's your safety glasses?

Jonno2summit: My thumb muscles are killing me! lol

ralph hainsworth: Where's your safety glasses??

Jacob S.: The funny thing about media I've noticed is that I've used the same pile of media for a LOT of tumbling! I only ever replaced it once but that was because I spilled it all over the ground lol You can get a lot of uses out of one pile.

Jay O'Connor: Great Vids, thanks so much. You say that consistency across the board is important so I think I already know the answer to my first question. Should I trim all my brass to the same length if it is under the Max Case length as this will affect the bullet seating depth? If so, how short is too short and are there safety concerns with 'shorter' brass? Thanks 

Samiam: Keep up the great selfless work you're doing sir. So I decided to go with a .260 Rem Savage Model 12 LRP mounted in the AWT chassis w/ Steiner glass. Two concerns of mine are finding materials to reload and throat erosion. Would it be easier/safer to resize .243 or .308 brass for a rainy day scenario ;o)? The other concern is how many rounds are you getting out of your .243 barrels before you notice throat/bore issues, i.e. the Ruger M77, and the wife's Remington?

Christian Mire: What do you think of the metal media polishing?

Mark M: Over 50k views! Mustangs are the best. I was opposed to the redesign at first, but it grew on me! I would definitely choose this color combination. It brings out the best in the car. I'd shine the tires up a little though because they almost look white in the sun. Nice video and even nicer Mustang!
