The 9mm has an incredibly shorter strain curve, with peak strain generally occurring because the bullet exits the situation. With this actuality combined with the bigger bearing surface and resistance while in the barrel of assorted 147-grain bullets, there just will not be adequate Power to reliably thrust them away from extended barrels.
TiteGroup isn't a good selection as it can get over pressure fast in 9mm when loaded hot. Id honestly Examine the BE boards, and look particularly at 9mm Main loads. Myself, I load 147s with TG for a cheater load :)
Recognizing these were being distinctive bullets of the exact same fat, I kept the powder demand over the low stop(using the outlined data for the HBRN bullet about the Hodgdon Internet site) at 5.0gr and played with seating depth until eventually it would chamber in the two the pistol and carbine I am loading for, had to lower OAL to one.055" before they would reliably chamber in each......very a difference between bullets of precisely the same fat and construction variety(plated).
The sole CFE data I could come across referrenced a Speer GDHP by having an OAL of 1.125. Just after managing a couple of They appear awful quick to me. In examining data on numerous other powders OAL is much longer.
Have to do a lot more perform with larger expenses, and try big vs tiny primers. The above data have been all smaller primer.
You really need to chronograph them. I am shooting a lightweight compact 9mm and was shocked by how Fewer snappy a good top conclusion load with 147gr XTPs was when compared to some 100gr plated I loaded. Sense is simply not exact. Motor
With these kinds of loads, there isn't a telling how again and again these 45ACP cases may read more be reloaded. They are really quite cozy to shoot a a hundred and fifty-two hundred round session within an lightweight/alloy framed Kimber Ultra CDP. My arthritis isn't going to like hardball loadings A lot anymore.
Notes: Recoil was just about every little bit as negative as loading up Yet another powder to +P pressures to find the very same velocity. Some soot on the outside of your situations tends to make me Imagine I used to be acquiring this speed at very low force.
Therefore the Room at the rear of the bullet in which the burning gasses are expanding, is escalating more quickly than it does that has a heavier bullet. More room involves a lot more powder if we've been to obtain exactly the same velocity, so lighter bullets use much more powder.
I centered on velocity functionality and report the velocities from my pistols for the most released pounds. Starting up with the most load isn't the proposed method for screening, and smart people will perform their loads up progressively through the beginning load anticipating pressure indicators. I also loaded A few other powders that list substantial velocities, for instance AutoComp, HS-6 and Longshot to compare relative performance.
In time, you will come to trust just one source, and maybe a few others as back again up. Another thing you've Doing work in your case is always that Newest 9mm pistols in great Doing the job buy, have lots of "head space" crafted into them. i.e. they usually are tricky more than enough to handle loads that exceed SAAMI spec - not that you're going to require it.
The main reason for your OAL dissimilarities is that I planned to find out if there have been any feeding issues from the P365, And that i experienced no concerns with any fees or lengths in this cfe pistol for 9mm array.
Blackhawk355 stated: Guy at LGS recommended some CFE Pistol to me. It works very well and I actually like it. Only trouble that I've observed is usually that it doesn't perform all of that very well with Solid bullets, which I use a lot of. Click on to expand...
Not posted in that thread, but I finished sticking with five.2gr because that's the place it felt finest for me.
