Hello to all:
The 10mm bug had been biting at me for several weeks now, and Friday I finally took delivery of a Glock 20, and one box of Remington factory cartridges to feed it. Tax return money came in Wednesday, and there was no stopping after that.
The recent snowstorm had collapsed the brass catching tent arbor on my pistol range out back, and with the cool weather here I was in no mood to chase and hunt brass on the forest floor. It worked on me all day yesterday, and there was no stopping the drive. I read about the 10mm being ditched by the FBI due to "unmanageable recoil", and got ever more curious as to what this "unmanageable" deal was.
Today, I went out, and propped up what was left of the tent with some forest scrounged poles and sticks, long enough to get some data. Chronograph set-up and ready. No way did I want to lose those precious 10mm casings, as they don't seem too plentiful right now. I did put in a back-order at Starline for 500, and maybe before the end of the month (I hope).
Well, gosh. What can I say. After 10 rounds, I was standing there, and saying to myself, ."What in the heck is so unmanageable about that?" To me, it was like a stiff 45ACP in my 1911.
I examined the chrono data. With 180 grain TC j-word, I got average of 1083 ft/s. A quick check of the brass, and yes indeed a bit of the Glock bulge was there, but I am making preparations to deal with that.
A Lone Wolf barrel is already on order, as is the Redding full length sizer for the brass. I'm eager to begin some experiments with 135-155 grain j-word hp's I have in my stock, and more so the two 175 grain castings I have.
My intention is only to shoot j-words through the factory Glock barrel, and cast through the Lone Wolf. It is my understanding these should interchange quickly after a field strip.
A question for the forum here. If I were working up to maximum velocities, lets say with AA#7 powder, or even Blue Dot, using 135-155 grain j-words, with new brass, would you see any issue using the factory Glock barrel with this?
Any other advice about reloading for 10mm? New cartridge for me.
Thanks.
