No, the fastest shot was #5 out of the 45. #3 was 1300.
I only shot 3 out of the short 45 and it was 1167,1165,1167. I am sure if I shot more rounds the deviation would open up some. The OM 45 has rather large chambers compared to the NM pictured above, from looking at the swelling above the web of the case. The NM leaves no noticeable bulge. A nice bonus to the cylinder I fitted.

You can probably guess, but I was going for bullet pulling increasing case capacity there with the dropping velocities. Guns are weird. All I know is that my 5.5" Accu-Sport generally is close to the books. We'll see what happens post-fire-lapping.

All I know is that my 5.5" Accu-Sport generally is close to the books. We'll see what happens post-fire-lapping. I haven't seen any bullet pull yet(knock on wood). That Mihec 45 has a good crimp groove if you can see it in this picture.  The Mihec 300gr 44 has tiny crimp grooves and I figured it would pull, but hasn't yet even when you load it in brass that has the neck split (10+ max loadings). The 44 is loaded with RCBS carbide dies, if it matters.  The weight of my revolvers and the way I grip them my also have some effect. When I come across the right deal on a 329PD I may learn a bit more about pull. Sorry I got your thread locked over on castboolits. Hope your BFR can be repaired to your satisfaction. |

I'm surprised those split necks don't give you trouble. I can see from the pic that neck tension is pretty good, even with the split. See PM on castboolits...

They are in the garbage now so there is no chance of trouble. Of course they don't split until you seat a boolit. The only problem they cause so far is that they fill that particular chamber with lube when you fire them.

I've been watching this one sense it started and have resisted entering. My input is this, how fast do you need to drive a sledge hammer. If I need to drive a 45 cal heavy bullet real fast, I use a 454. That's what it's made for. When I had my 45 colt built, I already had an LBT 300 WFN mold. I looked up some load data for the bullet and it said 21.5gr of h110. I tried that and got 1 inch at 50 yards of the bench(best of several groups) and I stoped right there.

I agree. My Model 83 mostly gets fed heavy 45 Colt, with thorough cleaning of course. A 300 grain bullet moving at 1300 does all I'll ever need.

I agree as well. I have stayed out of this one. I too have a 454.....

Yep, me too. I load all of my "magnums" to 1100, 1200 fps tops. From 32's to 511's. No 454 owned here.

I feel like such a wimp...I only push the 270SAA (280grs) to about 1100fps...I had no problem chasing elk with that load. I shoot the load consistently well out of my Bisley so that's what I took, when I go heavier and push them faster my groups tend to open up...to each his own but I'm not big believer in speed in revolvers. My "warm" 44 mag load is a 260gr at 1200 fps and it's accurate for me, I know it punches right through a 300lb pig.

Well, I think the most important thing to take from this thread is the difference in seating depths of similar weight boolits. My 44 caliber 300gr Mihec seats far enough out that a 26gr load can be shot in my Redhawk, where as a 300gr SWC may be unsafe at 23gr. Same with the 45 caliber Mihec. BTW, on page 2 my hunting loads aren't even breaking 1100  |

My go-to .500 Linebaugh hunting load goes 1,100 at the muzzle......

Groo here
That gun looks like an underload..
This is showing up in the bigger guns like the 460 and 500 S&W's and cowboy action [like ppc]..
People are loading them down..
The bullet is driven out of the case before the powder has got a good light[primer] then when the powder at last gets going--the bullet is stuck in the forcing cone and sticking back into the cylinder
causes a plug [ pipebomb ] almost all of this type of k-boom show no damage to the barrel but
total the cylinder taking the backstrap with it [letting go at rear]
