Ross Seyfried may in fact have sent load data to Hornady for pressure testing in order to "safely" publish that information for consumer digestion, but I know for a fact he has loaded ammunition that would not be for the faint of heart, as I've used said load information in my stock and custom 5-shot revolvers in past years. I have in my possession "some" of said load data in print as obtained from John Linebaugh. Ross did things with the heavy ,45 Colt, .475 and .500 Linebaugh that looked quite impressive in print, but he was certainly not the first to do those things, just the first recognized writer and hunter to present it to the public the way he did. Ross Seyfried is quite the marksman and hunter and certainly proved beyond dispute his ability to take large dangerous game with them. If Mr. Fowler believes he did so without much "hot rodding" of those calibers and utilizing over pressure load data, then one is just simply being unrealistic. It's quite possible that his thinking has changed and it appears it has, like many of us, Ross has come full circle and is back to shooting stock Ruger S/A's and enjoying life as well:-)

There is a reason those published loads are at those levels, going beyond there is asking more of a gun than you should... |

Well,nframe I know that my dad loaded 10s of thousand loades as well and a few years ago a 480 alaskan blew up in his hand...while it seems he was an avid and safe reloader all his life it only takes one...and you learn that that extra 50 fps is not worth the push...I believe Axe and Fowler make a great notation...If you like hot rods so be it...and let it rest not everyone agrees but everyone has an opinion to share so maybe you ought to leave it at that.... By the way the 480 had an extra round go off do to a sticky primer...

In a back issue of Handloader magazine Ross Seyfried wrote an article about "Turbo Charging" the 45 Colt. He had been shooting a 5 shot Seville that was built by John Linebaugh. In it he states that he worked up to some extremely impressive loads, loads that had been fired over a dozen times & the primer pockets were still tight, the cases (Federal) dropped out of the gun easily, in other words no signs of pressure.
When he had them pressure tested the following year they were right up there with a 300 Weatherby for pressure, he said he was very lucky & reduced the loads. Many times a full 2 grains of powder will only make 100 fps difference in velocity yet the pressure doesn't make the same increase.....its much higher.
Also in a back issue of Handloader Brian Pearce mentions getting "over" 1450 fps with a 350 gr slug in a 5 shot 45 Colt, this with a 7 1/2" barrel, I'm guessing the pressure is just a bit high. Probably not unsafe but that seems very hot to me.
We're all just guessing when it comes to pressures with heavy revolver loads, very few have access to pressure testing equipment so its very important to pour in a little bit of common sense when pushing big bullets at high "relative" velocity.
If there's one golden rule in handloading its, know your powder charge!

In a Ruger Blackhawk, 44 &45, is it generally considered safe for a max charge of H110 to be a full case without compression? Cast boolits if course. Seems that all of mine end up there yet my 300s never seem to break 1100fps.

Here's a different thought. What about an under charge of H110. Most manuals warn of going below 10% of maximum. If you do, there is risk of detonation, or more powder ignited at once, causing a huge pressure spike. Maybe the reloader had his powder hang up in his dispenser tube, or maybe he ran out of powder, and only got a partial charge, before he noticed. I don't know for sure, just taking a stab at it. Be interesting to pull the unfired loads from that initial box of reloads.

Seems that all of mine end up there yet my 300s never seem to break 1100fps. I would say that is an unsafe assumption. Maybe for one application, but obviously not for others. Think about stuff like the .357 Max or .44spl. The thing people don't get is that the max acceptable pressure depends on the gun more than anything. You can load .45 Colt to several different redlines for example. Your low velocity probably has to do with your 4 5/8" barrel (from what I've seen you post pics of) and case neck tension. |

Dick Dick...I remember that article too, but the Seville was a 6-shot with the frame window opened. It's the same one he took the Cape Buffalo with. Ross' 5-shot was done later on a Ruger Bisley. And I agree....Ross and Brian's loads definitely shouldn't be used in a 6-shot Ruger. Top end listings were at or above 50,000 PSI. -Lee www.singleactions.com |

Hopefully I'll get to do a bit of testing tomorrow with my OM Super and OM 45 Brassie. They both have 7.5" barrels and I still have some 307gr 45's loaded over 24gr of H110. I went back and gave them a stout roll crimp as well. I still don't think I'll get the velocities others claim(even from their Alsakans). For the 44's, I have a few various 300gr cast and jacketed that are loaded with 22gr of H110. It's a good excuse to shoot them anyway since I have had them 2 years without firing a round from them. |

Be interesting to pull the unfired loads from that initial box of reloads. I couldn't imagine loading straight from the powder measure, or from a progressive for that matter. Each round is thrown light, then trickled to level on the 1010. Straight into the case and a boolit seated before the next charge is thrown into the pan. |

 I would have bet that it wouldn't have broke 1300 considering what it does out of my 4 5/8" revolvers. |

Curious. Mag primers? How worn out is the brass. The 2.5" 686 .357 i had for a while taught me some things.
New Winchester brass with a mag primer was fastest. What does the inside of your sizer die measure? What does your expander plug measure? How thick is the brass? See where I'm going?
How did they shoot for accuracy?

I am pretty sure that is 2x fired brass. Winchester, CCI mag primers, and I have no idea about the die measurements. It is a factory 4 die set from Lee(I know I need better, I think). I also shot this load in a 4 5/8 today and got 1167. I didn't fire either of the OM's for accuracy. I actually didn't even fire at a target, just across the Chrony. I have fired the 24gr 45 load in the 4 5/8. Right group here:  The left group was with the original cylinder that had oversized throats. |

The lee dies are known for minimum sizing. A good thing in some cases, not so much for magnum revolvers. That could be part of it. Did your chrono readings start high and drop off as you emptied the cylinder?
