Some Help Please

[44MAG#1]

http://www.myhostedpics.com/images/Digglejiggle/group.jpgHere is a group I fired this evening. A 43/4 inch FA 454/45 Colt Starline brass/24.5 gr H110/Fed 150/ 340 gr LBT-LFN-GC sized .452.
10 shots with iron sights at 25 yards. I let 2 get away from me as can be seen. The other 8 is inside 21/4 inches.
What would you guys suggest. I don't shoot as much as I used too so am out of practice so to speak.

Maybe a bit more practice :)

Looks good to me and FWIW, you are using the best powder and boolit combo there is. What weight boolit btw?

I cant advise much.Getting the same type/size groups with my new Ruger Lipsey 44 special with full house loads. I am hoping with a good trigger job (mine is terrible) and a little load tweaking i can improve the group size.I am a better than fair rifle shot but other than tacital shooting with my 2 Comanders i have not spent a lot of time with a revolver.
My buddy up in K.C. has a 4 inch Super Redhawk in .454 that can shoot ten shot 2"or less at 25yards all day.I just never could with that much recoil and muzzel blast.

so what are you worried about ???

I'd trade ya a good shooting Ruger 45 for it straight across lol :)

In all honesty, I'd like to see the progression of the group. This group was 3 shots. By the time I got to 10 rounds, I imagine I be a bit fatigued and they would open up some.

I see the ones you missed! :bigsmyl2:
If you held real good the low ones might be uneven neck tension, they will have been the ones that felt harder to seat the boolit. They are faster.
Velocity changes can move shots sideways too. Make sure boolits are not creeping out from recoil.
Suggestions for things to look for anyway.
I hate to mention primers but yes, the SR primer might be moving boolits before full ignition making velocity changes because of changing case capacity from shot to shot.
Now I need to look at the two top left. Was it really you? Did you know it when the trigger broke? If so, ignore them. If not they might not have had near enough case tension and moved boolits too far from recoil or from primer pressure. That slows them and changes the spin.
Learn to ignore all shots that are your fault. If you call every shot to the sights, you are good to go.

I'd say too clean a gun in too warm a temp for the load. Shoot the combo some more and then rework your load level after the gun settles down if necessary before you jump off the deep end worryin about this or that.

Probably to the down side slightly.

I haven't chronoed this load yet. Does anyone know what may be a ballpark figure on velocity. I am not wanting to peg it out just a smooth working load.
Those bullets were water quenched WW.
This load is one grain higher than Hodgdons max for the 45 Colt in the ruger and FA section with a 335 CPB that seats roughly the same depth in the case as my bullet. They were using WLP primers too and Winchester cases.

Try switching to 454 cases and up the load accordingly to remove the "jump" to the throat.

If you think part of that is you, dry fire some while you are group shooting. Load 3 instead of 5 and spin the cyl before you shoot so you can catch yourself if you are flinching. I would expect that load to shoot better... My ruger will put 6 into 1.6" with less powder. I'd guess 1250 for velocity, but that is just a guess.

Primer is good.
Uneven case tension from case to case causes most problems.
The shorter case can too unless the boolit nose is long enough to start in the throat when you chamber a round.
Short brass has that primary jump to the throat that might not be centered. In effect, you have two forcing cones.
Bass has a point. Muck and lead up the entrance to the throats! :-)

You might try a lighter bullet ,, around 300 gr or increase charge slowly.
