Brass Trimming Considerations - Part 2

I've always thought this was an issue in my Reloading process. Thanks for your info and knowledge

Got check cases trimmed on my Forster now. Gave me something to think about today. Thanks for the time you put into this series.

best video on the subject ive ever seen Top Man!

Awesome stuff

Great video legend. Very informative 👍. Keep the great content coming.

Very much looking forward to the next video on the interior of the case necks. Thanks Greg

I only use a Wilson trimmer I found out right quick what a Lyman was doing to the necks. Wilson makes case holders for unfired brass if you want to square up the case mouths on new brass. A tube micrometer is a handy tool to have if you are reloading to check neck thickness variations. I wouldn't mind having a trimmer set up like you use especially for high volume loading.

Great Video Greg. I would love to get some Alpha brass to try, but I shoot calibers that end with Weatherby and Ackley. I do consistently run my new Lapua and Peterson brass through my trimmer. I never considered using a loop to inspect it. Great idea!:_CrossWhite:

Thanks for the info

What I have found is dry lubing has helped me, especially when reloading hunting rounds that will not be shot for months. Without it as you mentioned the bullet and case make a bonding effect, you can even hear it crack if you resize it say .001 deeper after being reloaded for months.

Great. Now I've got to get yet another tool for reloading. It never ends.

I have good results using hand ID deburring tools BACKWARDS. This keeps the blades from biting into and gouging the mouth. It makes it less sensitive to how much pressure is used. It also keeps from ending up with a knife edge on the case mouth. I find I get a more consistent finish as the process becomes less sensitive to having to have the case absolutely perpendicular to the tool.

I just scanned some Alpha OCD and Lapua brass with a 10x Loop and you are right. They both look pretty good, but the Alpha OCD brass looks significantly better at the case mouth and neck. We pay a higher premium to get Lapua, so why don't they spend an extra buck and put the brass in a partitioned box like Alpha does? No doubt that Lapua is the gold standard and has a death hold on competitive shooting but why not just add this little feature? I am sure that would cure all the dents and dings that aren't seen on the Alpha brass. Also, the look of the inner chamfer that you presented showed thickness variation on the inner wall. Maybe it's better to neck turn and also ream to be sure the variation is properly removed. I am normally ecstatic with .25MOA but lately, I have set a goal to push the envelope and see if I can get to .1MOA and so I am incorporating the things that may matter the most, taking notes, and practicing my shooting more and more. Thanks, Greg for these great discussions.

Fantastic, just fantastic, I was speechless when I listened, this is the level of detail I'm looking for! But my choice is Henderson, any comments to that? BTW, I have your priming tool - there is no substitute! The best there is!

My shooting is by no means "precision" shooting but I do like small groups...who doesn't. Still, I found the video very informative. Anyway, I use a FA Case trimmer and do an ID and OD chamfer, which works well for my kind of shooting, on a good day I can get 1/4 -1/2 MOA from my Ruger American 6.5 CM.

I believe the Lee tool gives very similar results. Cuts the brass, trims the inside and outside. No pilot needed, just a dedicated die for each caliber.

Speaking of necks, when was the last time you seen yours?!? 😮 Solid beard bruh 👊😂💁‍♂️

Not sure if you noticed the seating force change after using Giraud to chamfer the case compare to traditional VLD tools. F-Class John confirmed that the deeper angle the chamfer is, the more seating force you will get from a Hydro press or AMP Press due to the increased contact surface size after chamfer, so more friction between the brass neck and the bullet.

What do you use to magnify your cases? Thanks for all the great information.

Great education, thanks. Questions 1. Case neck welding. Like so many of us crank out loads, and then they sit forever. As you mentioned when you finally shoot them. I would say your preasure and speed change. Will Neo lube used on the case mouth cure this welding problem. Or should I unload and then reload for my next day shoot?
