475 Linebaugh, 340-gr WFN GC, and H110

[Naphtali]

I have loading data for my SRH 480s, using H110 (large pistol magnum primer) with .476-inch 340-grain WFN GC. I can find no loading data for 475 Linebaugh (FA M83).

Has anyone these data for 340-360-grain cast bullets?

29 to 33 gr of H110 should do it for you.

If recoil is a concern, and thats the reason for the "lightish" boolit, you may find the light ones at maximum loads to actually be LESS pleasant than a heavier boolit. I shot alot of 425's, and now shoot 440's. By far, the least pleasant loads I ever fired had 380 gr. boolits in them. Of course a reduced load with a light boolit will be a different story.

You can also use the loading data for 325 jacketed bullets for a start.
Good luck

BrettThere's that much wiggle room with H110?

[Lloyd Smale]

first i want to give my opinion. I think your wasting your time with those light bullets. good 475 bullets start at about 370 grain and go up to 420. If its low recoil your looking for your much better off (at least for a hunting load) to go with a 400 at reduced velocity. Now to your question. you never did say what kind of veloicity your looking for so its hard to give a powder recomendation.

The 350 gr boolit is the only one we got a Freedom to group at 1/2" at 50 yards.
Heavier is better for hunting to be sure but for groups you need to match rate of twist better.

What are you going to shoot with the 340-360 grain cast bllets? I am going to have a 350 grain bullet mold made this fall by Dan at Mountain Molds. I am planning to use it on deer and back bears.

Hodgon list data for 325 grain J-bullets and 370 grain cast bullets. You could just use a start load that is in between the two lowest weights. It should be safe.

Bullet Weight (Gr.) Manufacturer Powder Bullet Diam. C.O.L. Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure
325 GR. HDY XTP Hodgdon H110 .475" 1.740" 31.0 1480 36,300 PSI 33.5 1626 47,400 PSI

I have shot 420s in my FA and it about gets a steady diet of 400s. Mine tends to shoot 400s as well as the 350s and 380s. Maybe im not matching bullet weight to twist properly but ive done some pretty impressive shooting with my FA out to 600 yards with 400s. The only really light bullet i have is a 350wfn ballistic cast. It shoots well at 25 and 50 but falls on it face out past 300. For the most part the i get the same results in my linebaugh built 475 too. i also know that in penetration testing weve done the 400s leave the 350s in the dust. A 400 at even a 1000 fps will penetrate much better then a 350 at any speed. Im surely not going to sit here and tell you a 350 or even a 325 wont kill deer. Deer are thin skinned and killed easily with about any handgun. But to me with my big guns i want loads that will not only take deer but are capable i taking about anything. I dont want to fool with loads for deer and a differnt load for bigger game. The 400s kill deer just as well and do much better on larger game. Ive killed quite a few deer with my big guns but for the most part if im hunting deer i grab a 44 or 45.

I don't disagree with you, I love a 420 gr boolit and they all shoot good. But just for paper punching with the Freedom, the 350 showed an edge in group size. Same as the converted SRH. (To .475.)
For hunting, even deer, I don't go under 400.
What we have found with the 420 is that they need about 1/2 gr more powder in the Freedoms and SRH then from the BFR's. We get about 1" at 50 yards that way. With 350's we have got down to 1/2". So it is still a good boolit to play with.
The deal with the .475 is that it is such a great caliber that you just can't stay with one boolit and should have a lot of molds and stop buying the things! It is just too much fun to shoot to be buying boolits.
If Naphtali has a bunch from his .480, I say yes, go ahead and shoot them.

[BrettT/C]

I like getting molds to work with and do load development with. I am shooting 400 LFN GC and 340 LBTK PB bullets right now and the next bullet will be a 350 grain LFN GC. The 400 grain LBT works well but I want to have a flatter trajectory with less recoil.

I don't have a 475 but these threads make it fun to ponder what to get. Probably a Bisley with an octagon barrel and maybe done on a 44 mag nm flat top.

[frank505]

405 Keith at 1167 with a sd of 4 will shoot through buffalo, so it might even shoot through a deer, maybe. never shot anything else in my 475.

If its low recoil your looking for your much better off (at least for a hunting load) to go with a 400 at reduced velocity. Now to your question. you never did say what kind of veloicity your looking for so its hard to give a powder recomendation.340-grain 475's sectional density is equivalent to a 310-grain 45/454. And the mold drops WW, lubed and GC'd at 343 grains, give or take. Chopped liver it is not.

Lloyd, I furnish no velocity wanted numbers because I have no idea what the velocity range for bullet weight with H110 is. Since H110 is not intended for moderate loads, what is the effective velocity range with 6-inch M83?
***
The bullet is an LBT tangential ogive WFN with .400-inch meplat. The only significant differences I detect between it and my 405-grain WFN PB are crimp-to-base length and presence or absence of gas check. Regarding penetration, I intend to shoot both bullets loaded to velocities I want to use them into pine log ends side by side (Thank you Wes Daems.) My control will be "known" Speer 400-grain Gold Dot handloads. If penetration is what I want, that's that. If not, the 340 LBT reverts to moderate TiteGroup carry-gun loads for my custom SRH.

[Lloyd Smale]

I cant answer your question on the velocity range for that bullet because i gave up on the lighter bullets years ago. You state the sectional density is the same as a 45 colt 310 but to get equal penetration you have to factor in that the bullet is bigger in diameter and has a bigger metplat so it going to be tougher to get it through whatever your shooting it into. Id about be my life that a 310 45 colt loaded to the same velocity as your 340 475 will out penetrate the linebaugh. now switch to a 400 grain bullet and the 475 will leave the colt in the dust and with a 420 grain lfn casted out of an alloy of at least 18 bhn and shot at 1200 fps theres few guns of any kind that will run with the 475. Im with 44man. Ive got alot of handguns including 500 linebaughs and for years i prefered the 500 just because it was bigger but after years of testing ive come to the conclusion that the 475 or even the 480 are about the most versitile handguns a handgun hunter can own. they can be loaded down to 900 fps with a 400 and kick less then a 44mag and shoot through any game animal under a 1000 lbs and loaded to 1200 will shoot through anything. The 500s may have the capability to shoot even heavier bullets with bigger metplats but i havent seen where they put down game any better and they need a much heavier bullet and more recoil to match the pentration of a 475 and in most testing even then the 475 pentrates a tad better and with its smaller case its a more friendly round to download. If i had to go to only one handgun it would be a 475 hands down. I may critisize your choise in bullets as i think theres better ways to go but in all reality your bullet will work on any animal under 500 lbs and most people will never hunt anything heavier. But to get the real benifit of stepping up from a 45 colt or 44 mag you need to go to at least a 380 grain bullet and better yet a 400.

You guys are being very provocative, you have me day dreaming about .475s.
