1894 Fg

[68 couper]

Hey,
I'll be working up a load asap for a Marlin 1894 in 41 mag. Do these guns prefer gas checks? I have some Lee 410-240SWC done I was thinking of running over some Unique. Anyone had sucess? The range I'll be using is about an hour from home, so I'm thinking it would be good to bring some good guesses...

Thanks,
Couper

I've got a 1894FG and an 1894CCL both in 41 MAG and have yet to fire a cast bullet in either of them !

I do however have a Lyman mould for the 41 MAG , but as of yet have not gotten a suitable gas check .

So with the 1894FG I have taken deer using the Nosler 210 grain HP . And I have shot quite a few of the Hornady XTP's as well .

I think I'm gonna get some Gator checks for the 41 and try the Lyman SWC's in the CCL this winter [smilie=1:

Out of 9 different 41 cal moulds 0nly one I have is a GC. I use air cooled WW's with 1-2% 95-5 solder and have had no leading problems. I size all of them with a .412 sizer die that barely touches them. I shoot them in my 1894 FG, RBH and T/C. I have a SC 41032 that drops them at .412-.413 that I picked up because it was $10. My DC 41032 drops them at .410-.411. I'm going to HP the SC one.

Hey Mark,

How fast ya pushing your 41 stuff w/o gas checks?

Thanks,

6pt,

Call Larry@Gator check he has 3 sizes of 41 checks, give him the shank size of your boolit, I'm sure he can help you.

My 1894CCL requires 413 boolits, and does not need gaschecks to shoot the max speed out of a 41 mag case using slow powders. In addition, the gun will cycle a rounded-edge wadcutter with a 0.200 nose at 413, and will do 0.245 at 412. This means this particular gun is throated like a cave. ... felix

Hey Felix,
What OAL do you set up for?

Thanks,

[felix]

The maximum length that will cycle. ... felix

Between 1200 and 1600 FPS. I'm looking for minute of deer at 75 yards. Mark

I'm with you on that. Indiana just made a reg to allow pistol cartrages in a rifle this year. I've always wanted to hunt deer with a lever. I just couldn't bring myself to try out west. 6 weeks to go.... :-D

mark every gun is differnt but what my 44p really likes is the rcbs 240 swcgc cast out of #2 or 5050 ww/lyno with 19.5 grains of wc820/aa9 or 21 grains of h4227 wth a fed mag primer. It will shoot under 2 inch at a 100 yards with that load. I had dismall luck with heavys in it and mediocure luck with 250 plain based bullets. But it all came together with that load. The two other bullets that do fairly well in it are the 280lbt lfngc and the lyman devestator and both of these are gas checked designs.

The trick with shallow lands is to make the boolit the biggest that will cycle without a true hangup going into the chamber. The longer the nose portion of the boolit, the less the diameter it will accept. So, shooting the longer noses to make them fully work, the ogive must be more rounded, i.e., longer design radius. A secant ogive helps matters with the longer nose projectiles, obviously. We are talking the typical new Marlin cave/lawyer chamber/throat design. ... felix

The throat on my 357CB is .140 to the rifling.My MM Mold 185GC is snug on the rifling and my 180 Secant has to jump .050 to the rifling and a 180 XTP about .080 to the rifling.Luckily these are long boolits and shoot well with H-110 or lil-gun.The leade on the rifling is probably around 15 degrees,wish it were 3 to 6 degrees.If the chamber isn't perfectrly centered on the bore the short boolits in 41,44mag probably get started cock-eyed and deform.The faster they're pushed the worse it probably gets.I think some factory rifles are well centered chamber to bore and are accurate and others are off a little and cause a lot of grief.A chamber cast will show some having rifling to case neck on one side and a jump on the other.There is a good article on this type of thing on Mike Bellm's website.It would be great if the throat had 3 degree leade,.010 to.020 jump to rifling and throat diameter only .001 over boolit size.Boolit would launch straight,engrave rifling with out an abrupt land angle and not be going to fast to strip.Are there any factory guns out there that offer this for a decent price,sure would make a lot of us handloaders happy.Guess that's what keeps the custom shops busy.I guess that is why oversize long boolits often shoot better in mass produced guns.Might be better to buy a used gun and get a custom chambered barrel put on nowadays if you want ragged hole groups.

Well, I shot the 240 swc this weekend and yes, they do hang up. Accuracy was ok though...So now what?

I'd love to chamber a few lawyers... :roll:
