Hello my fellow reloaders,
I am having a heck of a time getting a good load for 147grain Xtreme Copper Plated Round Nose with CFE Pistol. I think the issue may be a lack of pressure in the case. The Hodgon website for CFE Pistol and 147grain XTP shows a max load of 4.2 grains at a COAL of 1.11". The Alliant Powder website shows data for a 147 grain Speer Gold Dot at a COAL of 1.13
It is a safe to assume (2) things:
1) rounds nose bullets are longer than hollowpoints and may need to be seated longer.
2) When adjusting COAL for a load, it is safe to start long and gradually seat deeper while looking for signs of overpressure at the primer.
I have understand that copper plated bullets should be loaded at lower end Jacketed velocities or higher end lead velocities.
I have loaded up these 147grain Xtreme round nose with 3.9 grains of CFE Pistol at a COAL of 1.160". After testing those, I loaded more up with the same charge of 3.9 grains at a COAL of 1.152". Both times I had a couple of failures to eject. Both times, I also had the firing pin fail to detonate the primer, up to 30% of the time 3x in one magazine of 10rds).
CFE Pistol is a medium-burning powder and 3.9 grains of it maybe fills 1/3 of the case of the mixed brass I'm using. I think that I may need to seat the bullets deeper, in order to decrease the volume the powder has to burn, in order to create more pressure, velocity, and blow-back.
I have fired a friend's reloads of the exact same bullet, using 3.9 grains of Unique seated at a COAL of 1.115". That load was more accurate while the load I'm describing are impacting to the right.
My Lyman 49th Edition Reloading Manual lists data for Speer 147 grain TMJ at a COAL of 1.115" and cast lead 147 grain at even shorter than that. It shows a profile of the TMJ and it appears flatter and shorter than the Xtreme round nose. Also, CFE Pistol is a new powder and I doubt if any reloading manuals list data for it.
1) Does anyone own the Hodgon Reloading Manual?
2) If so, it the same exact info that's available online, or is there data for more types of bullets?
3) Should my correct course of action be to seat deeper?
4) Anyone ever had the firing pin fail to detonate the primer while reloading for a Glock 17 (I'm using Remington 1.5 and Federal small pistol primers)?
5) According to other manuals, are 147 grain copper plated/fmj generally loaded short?
Thanks for any input.
