  1. ...and here is the charge variance data for VV N310.
  2. Local gunsmith has a laser engraver. Had my magazines marked with that.
  3. Hornady is even noisier. I have wrapped my case feeders in: 1. Silent Coat butyl noise dampening mat: https://www.silentcoat.co.uk/collections/frontpage/products/silent-coat-2mm-deadening-mat 2. Closed structure foam mat, something like: https://www.silentcoat.co.uk/collections/isolator Also put a lid on it. Helps also Mr Bulletfeeder noise.
  4. I also have Alpha-X mag pouches. Cannot recommend. The dovetails keep getting loose, and if I tighten them enough, the dovetail in the pouch body will start giving up... Just a bad design. Wish they did similar with normal screw attachment for the ball joint and then it would be a great mag pouch. Now they're just garbage. And yes, I am running the model with the detent ball under the screw that was supposed to fix the dovetails coming loose.
  5. Spread of 0.130gr is actually, in my opinion, pretty good result. I didn't have the analytical scale when I had a Dillon so I don't have good data of the consistency of Dillon powder measure, but generally I would say that most vendors market their powder measures with accuracy of +/- 0.1gr... 0.13gr total spread is about half of that. 0.2gr spread I don't personally like, as then I need a higher average to keep even the low end in major... I don't yet have that data, but friend of mine is coming to load some with TiteGroup in coming weeks, I'll measure the consistency of that too.
  6. I updated the table with 20 measurements per speed and did a similar measurement with Winchester AutoComp. Surprisingly the speed-dependant powder charge variance is even higher with AutoComp!
  7. Would be interesting to see the engineering diagram of the revised linkage. Did they tell you whether it will be a drop-in fit or does the installation require sending the powder measure to them? (very interested in this since I don't want my powder measure to be out of use again for 1,5 months...)
  8. I captured this data with the press empty except for the single brass that i was using for measuring the powder charges. So I had the case sized, primed etc. and just weighed the charge I got with that single case in the press. Difference in charge weight variation with different speeds was already remarkable, so I didn't really see a need to do anything more fancy...

  10. For this measurement I used 3 for index speed, top and bottom dwells just to have as little as possible variations caused by other things than the powder measure. Normally when reloading I've used 1900rph speed, index speed 2, dwells 1.
  11. Today I measured how the speed affects powder charge. Powder was Reload Swiss RS24 which is an extured powder, very similar to Vihtavuori 3N38. Balance was a very accurate analytical scale, confirmed to have max 0,0001 gram error. Once I have time I'll do similar checks with TiteGroup and AutoComp also. Units in the table are grains.
  12. I do like mine. Would be nice if there was a quicker way to adjust it though. I'm loading lots of different loads (9 major and 9 minor with different powders and bullet weights) and having to use both wrench and allen key to adjust it is lame. Some kind of quick adjust with e.g. just one thumb screw would be even nicer. But once adjusted, it has worked very well for me.
  13. In my opinion these should be reversed because: 1. swage hold down is a great die for... swage hold down. 2. sizing die with pin removed centers the case nicely for succesful priming.
  14. I had the same issue with the 3D printed part and noticed that if I fill just ~300 cases to the feeder, it works as expected. Fill more and you start getting cases upside down. Now I'm working on a new "bullet sense", that doesn't require the mirror assembly...
  15. I have the chute for loaded rounds and the fix for case feeder. Links available in the original Mark 7 thread.
