Brass Trimming Considerations

Your vids are always high quality and indicate things people don't always think about.

you are right . i noticed this myself only when i talked to others about it i was told i as crazy , and it didn't matter . and when trimming with a trimmer that trims off of the shoulder my loads shot better than ones trimmed off of the col . i made a holder/ jig that has a hole in it the size of the datum line on the case shoulder and takes a dial indicator with a insert that fits over the case mouth . slide case in and set zero . read all cases and you can tell the cases that will be 'flyers ' . i found in my gun cases with over .002 neck variance will be 'flyers' . and testing a new barrel it is looking like it will take cases with up to .003 before the ' flyers ' start . only my shooting is mostly at 100 yards . yea i know not far enough lol . can got out to 250 yards . but i like small groups . i'm getting just under 1/4 inch groups out of my varmint/ target ar with a 24 inch krieger bull barrel . the groundhogs around the house hate my rifle ! keep up the good work !

Excellent job. I was working this on and off to see the difference. Now I know from your video here. Thanks for the time and money you put into this. New Sub! Keep'em coming!

Now that was a dam good presentation. My hat comes off to you young man. You did not studder or even corredted yourself even once. That is a sign of proffesionalism

Aha…..finally a good explanation, I had that same issue sizing my 325wsm to 270wsm and could not find any info on that, my rifle shoots great for my needs with it but still had lingering questions…..thank you excellent video

Getting ready to start reloading 308 for PRS. First time reloader. A bit nervous is an understatement. Thanks for sharing this video.

Well done Sir, i have found the more consistent your process and brass before loading the better the results. It all matters.

Thank you for the knowledge

You can put your brass into a case gauge and measure the difference in neck length protrusion or extrusion in proportion to the rest. That is if they fit still after fire forming. Interesting how much variation in pressures due to friction of inner neck surface area to bullet. This is getting into squeezing the SD numbers down real low. Great informative video.

I greatly appreciate your videos Greg. Thank you! I would love to see you shoot a 20 shot 100yd group. I want to know what is possible.

Thanks.. New to reloading so pretty much over my head atm. I just got my apex 10 setup this week for 9mm and wanting to load 223 next week. Trying to learning all I can to minimize my errors lol. I got my Henderson trimmer in and Lyman pro die pack

As a newer reloader there is a lot her for me to learn from. I will need to rewatch it to pick out the finer details. One thing that would be helpful is at the opening a clear and simple statement of what your topic is going to cover and a restatement at the end. For me it was non until the last 5 to 7 minutes that I was about to understand what the information you were presenting was trying to convey.

Thank you very much for this information because many shooters don't know the difference and how difficult it is to work with the brass and each type of brass is different and has a different tolerance and has a different neck size and angle of the shoulder

New to the reloading scene, longtime ocd though with tolerances. Flyers seem to be just that, misaligned unit. Marksmanship can only cover so much when chickens are in a row. Anything mechanical that can be corrected, before proceding, is upon the human intervention, just as is the skill sets incorporated. Each has their own level of comfort when drawing down on fine tuning. One does not have to be in competions to find a need for better results, sometimes it's only what drives us in a personal satisfaction quest.

Way out of my league, but I did learn a few things, so....thank you.

Consistent head space after it goes through a full length sizing die. Mine is only a couple thou off of my chamber head space so I don’t think I will be seeing issues with head space variance. Are you neck sizing? Really interesting stuff. I’m going to watch more of your content.

People tend to forget that the ID bearing surface is also directly impacted by the chamfer.

What do you think of the hendson trimmer

Never heard so many disparities in such a short time 🙂 jk man, great content. I've been hand loading a long time and never gave that much importance to these disparities. Thank you

I have been reloading for 60 years, always updating equipment changing techniques and methods refreshing to watch your videos and not listen to people who think your techniques are over the top. Huge difference in bullets sitting force, especially start out with barns hunting bullets. What are your thoughts on this?
