Lyman 358665 /357Mag/H110 Good Or Bad?

[JesterGrin_1]

I have the Lyman 358665 and thought maybe I would use it in my Marlin 1894 with H-110 or W-296. Will the plain base work for this? Or should I keep the speed lower and use another powder I have on hand which is TightGroup? By the way this is the old Ideal mould and thus it is a square base not the bevel base.

Thank You for all Thoughts on this. :bigsmyl2:

Need more info.

How fast a velocity?? What do the boolits drop at? What does the barrel slug at?? Alloy?? Ect.
In the past I have used both those powders with a commercial version of that boolit.
Those were stout loads in .357 pistol. No problems.

Seen the very same boolit used to take deer. This was from a carbine like or similar to yours.

Boolit fit is king.

When I did check the bore was .357 thus my Boolits are sized .358 even though I may open the sizer up a bit depending on how they shoot. And as said this is the 358665 or as some call it the cowboy bullet. The norm is right at 160Gr or so.

The Velocity is the ?. How fast can I push them?

H-110 and Tightgroup are completely dif animals. The slower H-110 class powders will take much better advantage of the long barrel. Don't worry about velocity, just use standard .357 load data and find where it groups best. FWIW Lil' Gun will get you the most velocity but I produces much heat so I would not use it in pistols.

Jester--I've used 296 and wc820 behind the Lyman 358429 in the 15 grain range out of a Rossi Single shot, Win 94 and Rossi 92. as this is my revolver load. They run 1600 + out of the rifles and will group 80-90% into 3 " at 100yds. There is usually one or two zingers out of a 10 shot group going out to 4 and 5 inches. I'm not a hunter but if I missed a shot at a deer I sure wouldn't blame the gun or ammo.

[JesterGrin_1]

Fecmech is the Lyman 358429 a plain base? If so this is what I was looking for Thank You.

That boolit LOOKS like a Keith 358429 with a different nose, so I'd bet it will be just
fine. I load the Keith 358429 174 gr to 16.3 of H110 and it is accurate and fast. The
book has this at something like 1500 fps, but I doubt it out of my 6" bbl Ruger and S&W
revolvers. Probably more like 1350 or so.

You may beat that out of a carbine. The important part for accy and no leading
is diameter, base thickness, lube groove quantity, driving band sizes, etc. -- all of which
look the same as the 'known good' 358429. It also looks a lot like the 358477 with a
different nose, also an excellent boolit. Go for it.

[fecmech]

Yes the 358429 is plain base and 15/820/296 runs about 1300 out of my 6" Ruger Gp 100.

I use that same mould. My boolits drop at 165-166. I use 2400 with good results but haven't run them over the chrony yet, if the wind ever stops.....
I don't push any bullet much over 1150-1200 in my 4" 686. When you get old you get notions and I don't think they need to go any faster to do all the damage I will ever need to do.

MtGun44 I am going to give your load a shot with the Lyman 358665 and 16.3Gr of H-110 in a W-W Case and a CCI Mag Primer in my Ruger Security Six and my Marlin. :) They should be Zingers lol.

JesterGrin 1,

I know you were inquiring about a different boolit, but I too shoot the 358429 (173 grains) from my Security-Six and from my Marlin 1894…

H-110 worked well in the Security-Six…

15.0 grains for 1247 fps…

The Marlin is a different story. H-110 didn’t do so good as far as accuracy goes…

But 2400 and SR-4759 did…

2400…12.0 grains…1474 fps…

SR-4759…13.0 grains…1554 fps…

The 358429 is a flat base boolit. Minimal leading in both weapons…

Good-luck…BCB

[JesterGrin_1]

BCB Thank you. I may look into some 2400. But I sure wish I could do well with either H-110 or W-296. As when I started I was informed they were the go to powders lol. Sooooooo I have a few 8 pound jugs of the stuff lol.

Or heck maybe I can do a trade or try to. A 8 pound jug of H-110 for an 8 pound jug of 2400. Hmmmmm

[BCB]

JesterGrin 1,

H-110 may work well for you. I did O.K. but the 2400 and Sr-4759 did better! But, in all honestly, can a person really tell the difference in "better" accuracy from a lever gun? Maybe not...

I also have an 8-pound keg of H-110 and it gets plenty of use in the 44 Magnum and the 45LC also. So all is not wasted!!!

BCB

[JesterGrin_1]

Oh no I am sure I will use the H-110. Especially in the .44 Mag lol. But it would not hurt to trade one if I can as I have 3 8 pound jugs of it.
