***Contains load information. All of these loads were crafted by me for my firearms. If you plan to reload, get a manual for the caliber and follow directions in the manual. Start low and work up. Never jump directly up to maximum published loads without doing a ladder for each load in your specific firearm.***
I have several years of 10mm handloads, using 4 different powders, and 7 different (all 180gr) bullets. Most of these are in the upper range of published load data. Yes, I tried to get as much velocity out of my 10mms as safely possible, because why not? Basically, I wanted to harness the same power of a full house .357 Magnum out of a wheelgun, but only I want that power out of high capacity, semi automatic firearms. These guns have practical purpose in both the hunting and defense worlds. If I told you these firearms were solely for practical purposes, and not for a degree of hobbying and some "cool" factor, I wouldn't be telling you the whole truth. Guilty as charged.
As I worked up all of these loads over the years, I noticed no real taper in accuracy as the charges got heavier or to the point of "diminishing returns" (plateau) so to speak in their velocity performance, nor did anything seem overpressured by any observation of mine. (Never really can know without Lab equipment)
I found this interesting, as my experience loading. 357 Magnum and .44 Mag over the years, the diminishing accuracy and point of diminishing returns comes sharply as I worked up to near maximum or sometimes at say 3/4 the way up the ladder.........but this never really came in the 10mm ladders. Not sure if it has something to do with being semi-auto vs. revolver?? But in the 10mm...everything remained very consistent with accuracy and steady increases in velocity as maximums approached, with nothing becoming erratic or "spikey" in behavior. (Did I mention I don't like Blue Dot in 357 Mag!!!)
I kept some data, lost some data, and some I never chronoed them... and it got me wondering what is the FASTEST load for each of these 3 guns...
I have 10 different loads I've worked up over the years, and 2 factory loads I have on hand to fire as call it a "measuring stick" just to see where they stack up.
Going from left to right (all 180gr. weight)
All CCI LPP except #4 is WIN LPP
Each load has matching headstamps once fired brass, though headstamps vary between loads.
#1 - 9.3gr. Power Pistol - REM JHP OAL 1.250"
#2 - 14.0gr. AA #9. -WIN SXT-JHP OAL 1.2550"
#3 - 11.0 gr. Blue Dot - Hor. HAP OAL 1.2550"
#4 - 9.5 gr. Longshot - Zero JHP OAL 1.2580"
#5- 9.5 gr. Longshot- Hor. HAP OAL 1.2520"
#6- 11.0gr. Blue Dot - Hor XTP. OAL 1.2520"
#7- 8.7 gr. Power Pistol- REM JHP OAL 1.2500"
#8- 13.5gr. AA#9 - FED HST-JHP. OAL 1.2550"
#9 - 8.0GR Power Pistol- Berry's JHP OAL 1.250"
#10 - 14.0GR AA#9 - Armscor FMJ OAL 1.2580"
Factory Load #1 Magtech 180gr. JHP
Advertized Muz. Vel: 1,230fps. (Not pictured)
Factory Load #2 SIG 180gr. V-Crown JHP
Advertized Muz. Vel: 1,250fps. (Not pictured)
What im going to do is chronograph all 12 of these loads (10 handloads, 2 factory) through all 3 of my 10mms (CMMG Banshee, Glock 40 MOS, and Glock 20 with barrel lengths of 8", 6" and 4.6" respectively) (Glock 40 has Alpha Wolf barrel and Glock 20 has Lone Wolf barrel)by firing 5 rounds of each load through each gun. I'm curious as to what load will average the fastest in each gun. Will fastest in one gun be the fastest in another? Will AA#9 shine best in the longer barrel because it's the slowest powder? Will Power Pistol be best in the 4" barrel because it's the quickest burning powder? Or Will Longshot or Blue Dot just reign supreme in all of them?
As I said before, all of these loads were superb in accuracy from both the Glocks and Banshee...honestly I couldn't pick a winner unless I got a gun vise and did a series of testing... these all shoot better than I can.. these all put 1 ragged hole through paper at 10 yds fired off-hand, and the Banshee when shot from a rest at 30yds...same thing. One thing I can say for sure Is the 10mm is the most consistently accurate handgun round when pushed to the Max. Ive ever dealt with. I cannot say the same about 357 Magnum, 44 Magnum, or even 9mm or 45 ACP for that matter....maybe I just got lucky with the 10mm. Has anyone else notice this?? I've found the 10mm one of the easiest cartridges to load for, and consistently awesome results just about every time...granted these powder combos are arguably agreed on by many as "the best" for this caliber when maximum velocity is desired; I did take that into consideration when doing my homework on these loads over the years.
Will post results after a range trip in the very near future.
