By the way, Starline presents instances marked “9mm” and “9mm +P,” but their construction is similar. They may be so marked only to differentiate involving loads.
Your a reloader get started reduced and do the job up. OAL might make a giant change in velocity and force. Deeper seating indicates a lot less place or powder capacity so A lot more/Bigger tension for similar demand.
Obviously, all kinds of other bullet/powder mixtures over the years have generated some pretty exceptional benefits also. Don’t be scared to experiment with it, I have discovered several mixtures that accomplish just along with WST ever did! As well as, it erases stinkin’ copper! :biglaugh:
How clean up a selected load burns is right related to the powder's melt away level for the precise software. If you can get a lot of soot, it tells you your chamber stress is just too low. In the event you chronograph "sooty loads", odds are they are going to have large velocity spreads.
Other variables involve distinct bullets, another COL, a distinct large amount quantity of powder, distinctive primers and diverse brass. As a result, the concern is just not a great deal of whether or not my benefits match the printed effects, but as an alternative is whether or not my outcomes present that CFE Pistol offers significant velocity efficiency in general. The general outcomes (demonstrated in the tables) suggest that it does.
Each bottle of Hodgdon Smokeless Powder is assured by a century of producing knowledge and also the market’s most stringent excellent Manage procedures. To take care of uniformity, the chemical composition, grain shape and measurement, and All round density are frequently confirmed and evaluated in a ballistics lab.
Copper has a great deal more barrel friction than direct - yes, even just a skinny layer of plating. A plated bullet behaves much more just like a jacketed bullet going down the barrel than the usual direct bullet. Loading to very low finish lead data is risking a bullet stuck in the bore.
Precisely the same result is in Participate in as you pull the cause. When you finally ignite the powder, the Room by which combustion happens is not just the Room In the scenario. The full duration of your barrel results in being combustion space.
This really is an older thread, you might not get a response, and will be reviving an previous thread. Please look at making a new thread.
And just a FYI, but with 9mm Important loads, you cfe pistol data don't reload the invested brass a 2nd time. It should be fine for standard 9mm loads, but applying it for one more +P sort load is simply requesting a situation failure; getting out a $3k rig on the location when the case allows unfastened. And loading for approximately a .003" bounce, hence the second barrel from the below Image, With my rounds especially loaded for among my rigs looking such as this in the long run,
I observed one particular exam inside the Hodgdon Reloading Journal, he went right down to 1.050 OAL and acquired a little bit superior SD than I did. I don't Imagine I'll go cfe pistol data there. Capturing out of a four.one" barrel, hitting the FPS that I did, I feel I am near to the Max stress of a regular load.
The rationale for the OAL variations is usually that I wanted to see if there have been any feeding difficulties from the P365, And that i experienced no issues with any fees or lengths within just this selection.
Should you be just learning the best way to reload 9MM, you don't want this powder, as you could accidentally put an excessive amount in a circumstance and go much past reserve encouraged pressures
Commonly I'm not inclined to force plated bullets toward the higher reaches of released data. I feel that if you buy 9mm in bulk jacketed bullets are pretty near to the cost of plated
