So I read here on the forums about the "Quick Measure" powder throw and it caught my interest so I decided to purchase one. I contacted Tim Johnson from Johnson Design Specialties and spoke to him about the accuracy potential of the QM using Re-15, Varget, and 4831SC. Tim was a very pleasent guy to speak with and informed that the quick measure would throw the Varget and Re-15 to within .05 gr and the 4831SC to within .1 gr. I was excited to receive the QM from the UPS guy and was eager to try it out. I have a match coming up and have to load 200 rounds of .308 ammo so I was thinking this little jewel was going to make life VERY easy. I also shoot 50 or so rounds each Sunday after church at John Whidden's range and the ability to knock out some ammo on Saturday afternoon in a matter of minutes was an appealing idea. I purchased the "BR" model and a few extra charge tubes and they were shipped out immediatly.
I went into the reloading room and got everything geared up to start throwing some test loads to measure for accuracy of the tool purposes. My RCBS 1500 Chargemaster/scales stay plugged in for aclimation reasons and I recalibrate before each loading session. I pulled out 25 pieces of brass to use for my test lot and got them set up in the reloading block. I threw 100 charges to get familiar with the tool before using the scales to compare the charges for accuracy.
First thing I'd like to mention is the instructions are somewhat sketchy. I was able to get everything up and going but I'd like to see the instructions written for the common man, not the engineer type. After getting everything assembled and adjusted I began throwing charges in my target range of 43.2 gr of Re-15. I think it is a common thought that while Re-15 does not throw like a ball powder, it still meters pretty well. After throwing the 100 charges to get familiar with the tool I was ready to throw 25 and measure them on the digital scales. Scales are now calibrated and zero'd out. These are the results:
1. 42.7
2. 43.1
3. 43.4
4. 43.2
5. 43.0
6. 42.9
7. 43.2
8. 43.2
9. 43.0
10. 43.2
11. 43.2
12. 43.4
13. 43.4
14. 43.4
15. 43.1
16. 43.4
17. 43.1
18. 43.1
19. 43.2
20. 43.4
21. 43.3
22. 42.7
23. 43.1
24. 43.0
25. 43.2
So out of 25 charges thrown we actually hit our target charge only 7 times. We were within the .1 gr expected accuracy 6 times. That means that were more than 12 charges .1 gr from our target weight. To me, that's only a 50% success rate. Not real happy with those results. I am not going to send the package back yet, I want to give it some more time. My next tests will be with Varget and then with H4832SC.
Does anyone else here have any experience with the Quick Measure? Is there some kind of learning curve? I tried to make it a point to keep my technique the same for every charge thrown. Am I holding my mouth wrong or something?
