Bluetooth & thrower arrived. Works great, the thrower is definitely smoother & the Bluetooth connection is solid and easy - fast setup & operation. One wish is to have a single button press for a .01 trickle up for those times it finishes a kernel or two short.
(Felt odd throwing away the perfectly fine V1 board)
I’ve had work done by Accurate Ordnance and their product is reliable and built right. I’m lead to believe that you would benefit from doing a thorough OCW test to find a forgiving node. With a 24” 1:8 in a 6.5CM you’ll more than likely find it between 2720-2765fps or 2810-2840 fps ONLY if you don’t see pressure signs. I’m of the belief that if the rifle is sound (built right) it’s really a matter of tuning the load to achieve consistent accuracy.
Man you nailed both my mid and high nodes. 2750 and 2820. Berger 140 Hybrids.
I sent 300 pieces of Peterson brass off that was annealed on an AMP annealer. Couldn’t tell on most that they were annealed - but you can definitely tell when seating. Same batch the second go looked more like typical annealed brass.
I recently switched from a Rockchucker to Dillon 550 so I could more easily monitor seating depth on every round.
It's been working out great - my last 100 round batch all but 5 were all +-.001, and those 5 were re-seated to exactly .000 1st stage is an expander die .001 under bullet diameter, 2nd is for hand charging, 3rd for seating and 4th for measuring.
Thanks Henry. Currently I anneal every 3rd firing, I may step that up to every firing. I think I’ll find a better metering powder for my 223 and use automated drops for it, but stick to manual mode for the CM.
Can you tell me how you polished and modified the die?
I’ve read Scott’s paper several times, he makes some great points.
I haven’t measured runout yet, but I think I’ve got it performing at least as well as the Rockchucker. It too would vary +- .001-.002. You may be right about the shell plate though; that’s why I’ll have an instant indicator at station 4. I’m not going to worry about those that come up short, but if they end up a thousand or two long, I’ll back up and seat it a tad more.
I do think the 550 will speed up my loading process considerably.
Charging , seating & measuring becomes a single step, as does sizing and expanding separately with another tool head.
Now if I could just remember to have the ram up and case in place before I pour the powder, I can eliminate the vacuuming powder step as well.
Nope, thanks. It’s the entire shell plate, pretty much just stays where it is. Really curious if anyone else with a Dillon press and Forster die has run out of threads as well. Just seated another 50 Berger Hybrids and the +- isn’t so bad at .001 - .0015. A couple off by .003.
Moving from RockChucker to Dillon & per Forster (and Redding’s) instructions for their micro seating dies I’m trying to setup the die with the base of the die touching the shell plate. “...Continue screwing the die clockwise until you have fully compressed the sliding Die Chamber. “ The problem is using the lock rings supplied with the UniqueTek head and ram fully up, the the sliding die is exposed about 3/8”. Not enough threads left to screw the die down any further.
I notice the lock rings are “thicker” than Dillon’s, but I need the supplied rings for the pin hole.
I seated about 50 rounds of Berger Hybrids and CBTO varies +- .002 or so, ES .005 at worst. Wondering if not being able to fully seat the die might be part of the problem.
Thanks for any help.
(At least I’m getting better at ensuring the ram is up and a case inserted before I hand pour powder!)
The clamp screws below are not installed.
My planned setup is powder in station 1 ( auto thrower/trickler), powder check in station 2 (Varget in 223 & 4350 in 6.5 CM occasionally bridges & clogs the funnel), seating in station 3 and Redding Instant Indicator in station 4.
