I'm looking for 20-23k psi 45 colt loads with heavy LBT style bullets and Max OAL of 1.69". The hodgdon manual lists such loads as starting loads for 325, 335, and 360 CP LFN's with 4227, H110, and lil' gun. I'm wondering if such loads exist using powders like HS-6, AAC#5, or others. The bullets I am most interested in testing are the Beartooth 300 and 340 LFNGC, and the Oregon Trail 360 LFNGC, as I suspect these might prove to be accurate, based on what I've read. I checked loaddata.com, but couldn't find any such loads. Thanks for your help.

I'd check John Taffin's excellent book, bet you find something there.

Has the Book of the .45 been released already?

I'd check John Taffin's excellent book, bet you find something there. Dick I lent out my copy of "Big Bore Revolvers", but I was able to look through chapter 44 of "Single Action Sixguns". On page 327 I found a load going 975fps with The Oregon Trail 300 grain FP and WW231. This was the only load that I think might be in the range I'm looking for. Thanks Sixshot! |

I'll check this out. I did just find a 23k psi load in Handloader #217. It consists of a 305 Lyman 452651 GC driven to 1050 FPS by 21 grains of H110. Haven't found a load with heavy LBT's yet, but I'm on the right track. The pressure data from Hodgdon is actually in CUP, rather than PSI. Does this mean their pressures are lower in psi? |

My thinking on the particular LBT LFN designs I mentioned, is that more lead is outside of the case than other designs, could be safely driven a little faster. Tests will be conducted in 357-frame Blackhawk fitted with a long Bowen 357-frame cylinder.

. The pressure data from Hodgdon is actually in CUP, rather than PSI. Does this mean their pressures are lower in psi? Not really. I'm estimating its in the 20,000 psi range. No direct formula to convert cup to psi. I apologize for not stating it was an estimate, I've changed my wording. There are several loads that safely push a 310gr bullet at less than 1000fps in your pressure limits. |

Thanks Zac. About 950-1050 fps with 300+ grain bullets out of a 5" barrel is what I'm looking for. This would be an occasionally used hunting load. Not trying to loosen up a gun.

Ok, you guys had me worried that I missed a Taffin book release. My emotions are under control!

Handloader #275, December 2011 has that data up to 318 grn Bullets. Thanks. Zac sent me that article. It's that same Lyman bullet I mentioned before, but it weighs 318 when cast from wheel weights. The load in that article goes 1070fps out of a 5.5 inch Lipseys Flattop. That's a fire breathing beast of a load from such a small gun, but just what I was looking for. Thanks |

I would likely opt for the Longshot loads. High energy powder and has worked well for me in shorter barrels.
Had read the above information and have been working with similar guns.
After lots of experiments with different loads and bullets, I couldn't see the improvement with heavy bullets as I could with my larger, stronger guns.
Have been shooting blocks of wood, mounds of dirt, cinder blocks, etc just to see penetration and destruction.
Have settled on a wider meplat as opposed to more weight. I live and hunt in a heavily wooded area, but these bullets are working great out to 100 yards.
But, like most things, we all have our own ideas.
Best of luck to your endeavors. I look forward to reading about your results.

I checked loaddata.com, but couldn't find any such loads. Thanks for your help. I am addressing the 360 grain bullets. The 2 loads for the 360 using LIL GUN are 16.0 grains good accuracy and about 1000 FPS I went all the way to 19 grains and the accuracy was not as good, in my gun. That was disappointing because I think that 1200 FPS would hammer anything,, But things didn't come together for that with the accuracy. Maybe it will work for you. The other load was with H110 I ran from 19 grains to 21.5 grains and the 21.5 grains gave the better of all with the less deviations. The 21.5 gave about 1200 FPS Use a mag primer in both load Powders. I do like the 360 grain Bullets I can't remember if it was 6" or 8" high at 50yds but I do remember them printing higher. I had been using the 270-RCBS-SAA Prior to that shooting session. I hope this helps you. |
