6 inches with a stock Ruger is pretty good isn't it? Will the rules allow a custom line bored cylinder and a matching custom barrel? ;D

Not for what I want to shoot with it. I'd like to trim group size down a bit before I enter a match with it, whta are 44 caliber throats supposed to measure?

NBY, are you using Elmers old load with the newer Alliant powder or the old Hercules 2400? There's enough difference with top end loads to cause pressure problems.
In recent tests Brian Pearce said that 20.6 grs of the new Alliant gave equal velocity (pressures) as 22 grs of Hercules. If you think you need more velocity with lower pressures switch to H110 & a mag primer.
Remember that you need "dwell" time on the target with your cast slug, if they break up too fast you need to rethink your velocity or your bullet weight.
I'll be shooting at Wickenburg every week in feb-march-april.

I have no experience with 44 mags but I know in my 45 colts I get the best accuracy out of heavier LFNGC styled bullets, especially at longer ranges. would think a 300gr LFNGC for your 44mag could be the cats meow but testing will prove that to be right or wrong. Max charges of H110 and a mag primer would most likely get the best long range accuracy but might prove difficult to shoot that much recoil over the course of a match.
I have never shot Silhouette so I don't know if you could mix ammo but if you were able to run a lighter load for the chickens and pigs and then go to a heavier load for the turkeys and rams (knowing the sight settings required for each ahead of time). Like I said I don't know if it is legal to switch loads in a match or not. Going with heavier bullets should get a more stable bullet and one that will hit the target with more momentum to knock the rams down.

I have dipped into my sockpile of HErcules 2400, and to the best of my knowledge there's no rule that says you cant switch ammo

In my long barreled supers, the RCBS 300 SWC (used to weigh 313 grains from the supplier that I got mine from) that you can get from several casters around the web shoots VERY small groups from the bench at 100 yards. In fact, I will not post the typical groups where I don't get called a liar, just see what it will do in your gun. I get about 1430 fps from the 10.5" guns with 21.5 grains of 296 with a WLP primer.

Sierra 240 gr. JHC driven by either 23 or 24 gr. 296, or 21 gr. 2400 & CCI 350 Mag. Pistol primers.

NBY, don't get to cought up in change for change sake. When working up loads for long range, you only want to change one thing at a time. IMHO the bullet you are shooting is not the problem. It's the powder. 2400 is great for normal ranges. Try 296, H110 or AA#9 with that bullet.

Went out today with a box full of Skeeter's pet 44 Mag load with Unique, didn't get better results, actually went the other direction and opened up by about 1". Might have to try some H110 behind the old Keith bullet, anybody got a suggestion as to amount? The manual I have doesn't list 110 with a 250gr. bullet.

Need to be thinking about sights.... Didn't Bomar make a Blackhawk rear sight just for the Silhouette shooters? You got a nice patridge front? I just picked up another ISGW rear for a FA... This is the rear sight that FA puts on their Silhouette guns... Early on they used a Bomar... My 32 mag H&R FA 97 set up for silhouette has a front sight that is adjustable for width and height....

I'm thinking about the Millet rear sight, as Bomar is out of business. I have the factory front and a Burris scope on there right now because I'm trying to figure out which load it's going to like. As it sits right now the Keith 44 Mag load is getting the nod, but I haven't tried the heavier bullets yet.

whta are 44 caliber throats supposed to measure? According to Jim Stroh, in his article on his website (www.alphaprecisioninc.com) entitled "Revolver Accuracy": "When cast bullets are used, the bullet should be .0005 to .0010"larger than the barrel groove diameter. Ideally, the cylinder throat will be .0005 to.0010" larger than the bullet. To illustrate, Douglas .44 handgun barrels typically have a groove diameter of .429". The cast bullet should be .4295 to .4300". The cylinder throats should then be .4300 to .4305". Jacket bullets are more tolerant and can be groove diameter + .0010. Cylinder throats .0010" larger than bullet diameter." |

Well, I settled on a load, 250 Keith over old Keith load minus 1 grain. Took the scope off and it's on it's way to the smith for a deep crown, fix throats, 11 Deg. forcing cone, and an action job, should have it back in a month. With Bo Mar being out of business the chances of me getting one of their rear sights are probably pretty slim.
