Really enjoy your videos. Very thorough explanations plus gems included. Thank You
Glad you like them!
I’m still getting my system down - just started neck turning & sorting bullets - and pointing bullets is next. I’ve been reluctant to use my 650 for anything other than bulk 9mm and 223 but Erik’s bullet flow system is making me think about it.
What ensures that the shell plate is stopping at the same height every time. Do you screw the die down until it touches?
Great Stuff John 💯💥💥💥💥💥💥💥
Thank you
After sorting, you go straight to pointing? No need to trim to a uniform length first then point?
No, I'm not trimming anymore. Just sort and point.
I see you’ve flipped you tablet. Did you zip tie the cables behind it so it takes the pressure off the plugs?
No I actually forgot, so thank you. I just ran out to the garage and secured it.
heck ya!!!
Are you using the Armanov floating lock rings or locking the dies solidly to the toolhead?
Neither. I make my own floating rings but same concept.
Nice.
So you're sorting on length and not weight?
I still think for what you all spend on premium bullets, the manufacturer should be doing all this sorting for you and providing them in sub-batches. They could automate all that on the line once they are keepers, just kick out into different bins and bag them labelled with the range.
@jeffb.3052 I agree with you - I’ve had huge weight discrepancies of late with the top end bullet however unless I get 50 out of spec they can’t (or won’t) do anything. A premium product at a premium price should be a premium standard...
Weight discrepancy is hugely overrated. If you take the worst case discrepancy in a 500rd box and run them through a ballistic program there's virtually no difference in impact and BC, if I remember right, the last time I did that excersize it was less than an inch variance at 1000yds. I can tell you that if I wasn't sorting by OAL and pointing I would just load straight out of the box even for with zero hesitation for major matches.
@@FClassJohn so are you saying that the 1.3gn difference (in same box) is irrelevant and won’t matter and I should focus merely on OAL? Or OGIVE rather than weight? I’m intrigued.....I’m sure you have a video on this also so shall search the archives 😉
@@FClassJohn good to know because I got lazy and quit sorting a while back. I saw zero difference but I wasn't shooting long either and why I asked.
Is this sizing the O drive?
This is simply measuring the overall length
What happened to strait 284?
It went bye bye about a year and half ago when Lapua temporarily stopped production of the brass but to be fair, I'll never go back. The 7prcw is just too dang versatile for me.
So bullets are sorted by over all length? Not base to ogive?
Yep. I haven't sorted BTO in years. Some people do, and that works for them but not for me. I sort to length, point and shoot.
You want to sort bullets where the biggest variable appears. For most its base to tip. Also longer bullets will have an ever so slightly higher BC which will appear at 1000 yards, so batching by OAL will minimize your vertical dispersion!
Thanks guys
Hey John whats on top of the primer tube?
I add a weight to ensure the primers are pushed down with a little extra so that no primer is missed. Because I have the autodrive running I have to make sure a primer is loaded onto the primer slide every time. I'm actually going to make a newer version that's even better soon.
@@FClassJohn much needed. The primer system is the major fail point imo for dillon/mk7. Gosh that can that thing jump when a primer is screwy. And it gets on a roll of missing them and makes a total mess. 🙄
@@theturkeysopinion Once I have a better system for the primer tube I'll do a video. But I can tell you just doing the weights has helped immensely but it's a real balance to keep it from breaking the rod when all the primers are in because of the flex.
@@FClassJohn awesome. Looking forward to it👍👍
@@FClassJohn I was having to watch the last couple when priming on mine. I added a 45acp case with an area 419 funnel head tapped to it. So far seems to be working good. Was afraid to add too much weight to it.
It seems like somebody should make a bullet swaging die to make all bullets exactly the same.
Tough to swage bullets without risking jacket delamination or deformation.
I have a Corbin swaging system to make my own jacketed projectiles, you’ll never be exactly the same for all projectiles. If I can maintain within a one percent variance weight/length I’m happy
@@KS_Penetrator What did do make the jackets from?
@@WeTrudgeOn I’m currently buying from a distributor but in the future when I get tooled up I’ll be producing my own from coils of copper
@@KS_Penetrator That is pretty cool. I'm a retired tin knocker. I've worked with thousands of pounds of sheet copper over the years. Are there several steps in jackets with annealing in between?
Do you point first
No I don't
@@FClassJohn thanks for the info
