I’ve had bad luck with Aguila brass from loaded ammunition. I have never bought their brass new.
Aguila 45 ACP brass is so thin that it sizes differently.
45 Colt brass had serious problems with split necks. I actually had necks split on the very first reloading. It also had very aggressively chamfered rims, which were noticeably more angular than any other brand I’ve seen. To be clear, that’s not a problem, just an observation. It does make the brass look more streamlined.
45 ACP using the 152 Grain Semi-Wadcutter Bevel Base “Penn-Maxx” 7th generation bullet. They are supposed to also be accurate at very low speeds.
I measured 10 of the coated version, and got an overall length of 0.5695″ (Range 0.5680 to 0.57) with a weight of 156.9 grains (range 157.4 to 156.5). Pretty good! The coating is more like a graphite dusting — it cuts down on smoke but I feel like there is still exposed lead in the air.
I found that some of the Hornady FTX seating stems — for hollow point, or nylon-tipped bullets — worked very well to seat these bullets, because the stem pushed only on the flat shoulder of the round. The nose is very small, and I found that bullets had poor concentricity when seating by pushing on it. I believe it does not “guide” the bullet in well because it is small and sharpish.

|Powder Charge (grains)
||S93. Never ejected or cycled the slide, but always fully cocked the hammer. Worth investigating with an ultralight action-spring
||S94. Mostly cycled, some failure to lock back slide with firm hold.
||S95. Cycled slide, but failed to lock-back on empty when limp-wresting.
||S96. Very clean holes in paper. Occasional gas blow by.
|#47.75 ≈ 4.5gr Clays
||S157. Very clean holes in paper. Still got occasional gas blow by.

||S136. Winchester nickle plated brass.
||S135. Winchester nickle plated brass.

From the table above, Velocity (fps) ≈ 91 + 184*grains_of_clays.
Most of these loads are below start loads for a 155gr SWC.
Hodgdon says, Winchester case, Fed 150 Primer, 1.230″ OAL, “155 GR. CAST LSWC”, 5″ test barrel:
Start: 4.9 gr Clays 1,040 fps @ 16,100 CUP
Max: 5.2 gr Clays 1,082 fps @ 17,700 CUP
The total loaded round is about 250 grains, which is neat.
500 Linebaugh loads using the Cast Performance 435 grain WFNGC “wide flat nose gas check” bullet (sized .511 nose .380 meplat .410″). This is the older version with blue lube.
Because of the gas-check I only pushed these hard. The wide nose and supersonic velocity means a lot of drag (I measured a loss of 2.2 – 2.5 fps/yard). But it also means a lot of damage on impact.
All brass is Starline and previously fired. All loads used CCI 350 primers, to match load data. I seated to the cannelure, not a specific OAL. 7.5″ mag-na-ported barrel.
||28 = 1244 – 1216
|Acc. #9 23.9
||134 = 1245 – 1111
||38.32 (10x) [11.82 removing only min]
|Acc. #9 24.2
||103 = 1255 – 1152
Approximate drag – 2.2 fps/yard at 1230 fps.
Notes: Lots of recoil. Accurate #9 performed well, but sometimes had an unusually weak load.
H110 is highly reccomended by gunsmiths, but no manual has data for it with this slug. I used 27.0 grains of H110 to start, and felt safe with this because:
Taffin Tests used 27-29 grains of H110 with 440 grain projectiles.
Lee Martin says his “top-end 500 Linebaugh” load is “29.5 of H110 with a 435 WFN”. (Almost certainly the same Cast Performance slug I used.)
Hodgdon says a 468 grain LFP is 31,700PSI with 30.0gr H110 and 35,100 PSI with 31.5gr H110. A 425 GR. LFP (w/GCK) is 29,100 PSI with 31.5gr H110 and 35,200 PS with 33grains.
This thread recommends Winchester WLP for the 500 (supposedly per John Linebaugh himself), because it lowers pressure.
“Brian Pearce shows a 13,500 psi increase from when switching from WLPs to 350s with a 100 fps velocity increase in ruger 45 colt loads using identical charges of enforcer powder.
“. (That’s in a Handloader article)
The CCI350 has always been the other stand-out favorite.
