Need help understanding why the over pressure of a set of 10 cartridges fired from a ultra light Taurus Judge (2.5" 410 chamber) 5 shot
All 10 were hard to extract
3 of the 10 had primers backed out aprox 1/32~1/16"
All 10 had black soot back down case 50%~75% from mouth toward head about 33% of circumference
5 of the 10 had unusual primer indentations/shape (deep firing pin dent (2), flattened primer (2), primer cup outer shoulder raised lip around circumference (1))
All 10 had sharper report and harsh recoil compared to similar factory loads shot same day
All 10 left significant powder fouling and unburned power in the barrel and cylinders
Loads were produced in climate controlled house and shot on typical Texas spring day at 75 to 81 Degrees OAT from a modestly warm revolver (5 rounds of factory shot first from bench at a relatively slow concentrated shot pace)
New to reloading pistol..... similar loads with 6.7 gr Universal function properly
Set up with Lee single stage presses (3) and a RCBS for crimp stage
Very accurate RCBS Range master 750 and Lee balance beam scales
Every load weight checked twice (I am scared to death about double loads and inconsistent Lee so called "perfect shot measure")
Lee carbide deluxe die set (I think set correctly as other loads function correctly)
I used once fired 45 Colt C-B-C brass at 1.280" for 30 of the 50 reloads
and 20 New Starline (larger primer hole .140??) at 1.285"
Bullet works 200 Gr LRNFN--- Brinell 22
COL was set for 1.595 (load data indicated Min OAL 1.600)
Winchester Larger Pistol primers (cannot get any other brand locally and have been on waiting lists at every mail order house for months for CCI and Fed
Load was not "worked up" from starting grains (I accept the ire that will cause and pledge to never use this method again)
Hogdon web site for HP-38 had spread of 5.9 to 8.0 grains
I picked 7.0gr as assumed safe-- and checked my three load data books against the web site load data
Aside from chewing my *** for not working up a load please teach a old dog some new tricks
Most of my 45 colt reloads for the Judge and Uberti 5.25" leave unburned powder in the barrel
I have reloaded with Hogdon Universal, and HP38 with Tight-group and H110 available
not too sure I like the very small load charge in the giant assed case
I bought the starline new brass not knowing what .140 primer hole means or if it makes any difference in 45 Colt with Large Pistol primers ( the high pressure indicators noted above seemed to be spread evenly across all 10 shots (5 of each brass))
Too chicken to try a few of these in my new Uberti 45 SSA so I pulled all the bullets and dumped the loads
You may wonder why I shot 10 rounds with high pressure indications...
First cylinder full I deliberately chose the shinny new Starline brass and aside from louder and harder recoil... they shot well and nice group (2.5") where I was aiming 25 yds away it was during reload that the brass was hard to extract and had the sooty blow back
I looked over the revolver well and decided to shoot a cylinder full of same load in the once fired Colt brass... unfortunately they were also hard to extract so I segregated the ammo fired a box of Universal 6.7Gr loads, a half box of factory loads and went home to examine my spent brass and scratch my *** about why
Looking for more info on how to read spent brass for high pressure I ended up here where UncleNick excellent sticky post helped generate more question...mostly why would a seemingly safe load function with high pressure indicators....
I tend to wonder if the design of the Taurus Judge long cylinder has something to do with it...or more likely in my opinion a very low volume load in the large case may be the culprit as I keep reading about cowboy action folks doing some sort of shake the gun before firing to "stir up the powder"??
Gentleman I invite your thoughts and opinions and the inevitable *** chewing I deserve
Sorry for the excedingly long first post
