I learned during personal barrier testing that the Golden Saber is one of the toughest bullets on the market, followed by Gold Dot. Once in awhile GS will have a jacket separation, but it's rather rare compared to other brands.
Shot out one of the supports on my chrono, when the replacement arrives I have some 200XTPs to test out with AA #9 and KKM barrel.
I misread your post on bullet length.
180gr GS random sample is .635" long;
200 XTP random sample is .684" long.
The only Sierra bullets I have are rifle calibers, hope the above helps.

Since this is the Accurate Arms powder data post area, would you e mail me a synopsis of your barrier testing with the Golden Sabre's and weights tested...please. Barrier penetration is a area I am keenly interested in and I especially wondered about the Golden Saber's.
YOu could just e mail to: ppro.........@.....mychoice.cc
KKM sent a replacement 6" barrel because of accuracy issues with the first one, so it's back to testing again because every barrel is different. Stock recoil spring/rod.
Using data from Speer and Hornady manuals, started out with 11.4grs and both manuals have a maximum of 12.0grs with their respective bullets.
180gr Win JHP notched - 1373fps/753fpe, ES 24fps, SD 09fps
Power factor with both rounds in excess of 240 and a milder felt recoil than 10.7grs of HS-7 @1286fps/661fpe - old KKM barrel w/22# recoil spring/steel guide rod.
Replacement KKM barrel excellent on demand, freehand accuracy at 55 meters with both bullet loadings. No pressure signs.
I've started using the Win JHP notched more frequently in the last few months in multiple calibers; like what I'm seeing, especially in barrier testing.

at 11.4, all rounds had flattened primers, and had a case ring diameter of .434 (my gun's observed max).
at 11.1 all rounds had flattened primers (not quite as bad as 11.4), and diameter of .434
at 10.8 some flatter primers, case diamater from .433 to .434
I'd feel safe probably up to 11.1... but know that 10.8 is better. I'll do further testing in this area.

All cases at all loads have flattened primers. At 11.4, primers filled all voids of pocket, and hung the cylinder on either a stuck case, or stuck case on firing pin ring on receiver face
11.1 showed no tightness when removing cartridges. Would call 11.1 max load.
I shoot a G-20 with a stock length Barsto Barrel. I have been using a published recipe of 11.0 gr of AA-7. 1.250 OAL. WLP, and a 180gr. Rainier FP bullet. Without the benefit of a chronograph, I saw some of the same indications over 11.0gr. The published speed on this @ 11.0 is 1200fps, so I imagine you are seeing a bit more velocity with a 6" barrel. AA-7 is a primer flattener, no doubt about it, and it burns clean, and meters well. I have tried other powders, but I am still happiest with AA-7, no matter where it is made. Thanks for publishing your data.
I'm going to do some #9 test loads. I'm starting with my 180 Rem FMJ, but does anyone have approximate start/max load numbers for Rem Golden Saber 165?

Followed load data from two sources, Hornady book and Accurate web. Accurate listed loads from 12.2-13.5. Hornday started much lower and went up to 14.9
Glock 20, 6" Glock Hunting Barrel
at 14.9, rounds had semi-flattened primers (not squished). Rounds were maxing at .433 case diameter. Didn't make .434 (my gun's observed max).
From 14 up, recoil was assertive.
All loads seemed to leave a lot of crud behind unburnt or dirty powder... lots of little yellow flecks

Flattened primers appeared early. Have to reexamine cases for more detail at different charges.
If I fire one shot at a time and open cylinder, I didn't have problems with the cylinder not wanting to open. Cases always extracted smoothly, no bind. If I fired 3 rounds in succession, not opening the cylinder, I did see some issues opening the cylinder above 13.1 gr. Cases are never stuck to receiver face. It seems it has something to do with the gear in the center of the cylinder. Cylinder turns easily.... so not sure what's happening
ok, good to know. I haven't had any issues with the 1.26"
I've found a problem in my reloading practice. When I load longish 1.261-1.266; and when I have a longer than normal case, I'm getting a bulge in the bullet from my crimp. I'm fairly certain this affects my velocity readings in my pistols...and other uses.
Need to get a .40 bullet comparator or drop in round checker to avoid this
I'm waiting to see if it's ok to put non-pistol, 10mm data here... but as a tease, did you know a 180 Rem fmj on 14.5 gr of #9 will do from 1530-1550 ish in a 16" gas-op 10mm ar?
