I load for accuracy and have no interest in rouding from the best load. Question doesn’t make sense to me. Zero 200gn L-SWC does best with 4.9gn 231/HP38, and PD 200gn L-SWC does best with 4.8 gn 231/HP38.
My question is why was 148 gn (9.6 g) selected for .38 wadcutter and 147 gn (9.5 g) for...
Measure bullets--they vary (besides length variation, even the shape varies as they don't all come from the same die or mold)
Measure factory ammo--they vary
Measure COL pulling handle hard vs slow--they vary.
All a manual tells you is their test COL. You find the COL best for you--then you...
Just a note:
If you can SEE a bulge, throw the case away.
If you can't see a bulge and the 'plunk' test shows the hang up is a bulge down near the extractor groove, you can bulge bust that empty case.
Some folks like me, after having their P08 "Luger" choke on a round with a raised ridge near...
I stopped all cast bullet sizing in the late '70s. Did a lot of testing and sizing never improved accuracy.
There is not, in general, a single correct size for bullets, other than what your gun likes.
For lead bullets, the bullets must be the same or larger than the throats of your cylinder and...
Dillon TELLS folks that they still have to lube their cases with the carbide bottle-neck dies and that they are only made for ammunition manufacturers who will be pumping out millions of rounds. The carbide dies will last for several million rounds, the steel dies won't. Yet, I heard one person...
If you are shooting at distances of 300 yds or greater, and you have two loads with "the same" accuracy, the lower SD will most likely be more accurate at long range. For most of us, SD is meaningless. It is the target that tells the tale. If the trajectory matters, then you will find that out...
It certainly should be a direct switch.
Maybe you need to adjust the sizing die, as it might be stopping the ram short, and the other dies will then be fine.
Not sure what the confusion is, but:
The case establishes how high the powder die must be. If it is screwed in too far, the case goes up the expander section and into the case mouth flaring section and, as you try to force the ram higher, it is forced to "rip" the case mouth open. Where your...
Really sounds like powder falling out when you open the breeze shield.
Watch it and see if you see any kernels fall into pan when you open the shield.
I have never had that issue.
If you are using it, remove the McDonald straw. If not, try it.
Talking about free repair/replacement on my three 1050s with Dillon. I was more than happy with my L-N-L, until a 1050 practically feel in my lap ($800 with four toolheads and caliber conversion for about six cartridges).
One of my three came completely disassembled to bare bones and I had to...
Lead bullets and a factory crimp die is one the really fast ways to get barrel leading, poor accuracy, and key holing. For lead bullets, use a standard taper crimp die and remove sufficient case mouth flare. Hold the case up to a white background and be sure you don't see any case mouth flare...
I love all three of mine, but I have had issues with the case collators.
All of mine are used and Dillon happily has done replacement/repair work on them over the last 15 years.
One of the sales folks say they can tell a COMMERCIAL machine when it comes in.
1239 fps? That is most likely somewhere between 5.8gn and 6.3gn, depending on your lot of Unique...
5.7-6.0gn is generally where best accuracy if found.
>Why do you prefer AA 2 over 5?
Just accuracy. All my .45s seem to prefer very fast powders.
