Interest In Miha Brass 454190 4-cav Solid/HP

[.45Cole]

-something that drops easily into cylinders (RN) and retains somewhat of a flat nose
-something that can produce many boolits (4cav)
-has the ability to be sized down to .452 but will be large enough for oversize throats
-weighs in at about 260grns (solid) so that it can be pushed fast for long range shooting without a lot of recoil

What say you???

[45 2.1]

Something like this?

I am in if it will drop at 0.455" in WW.

If its a true Lyman 454190 I'm in. I want one with the 190 meplate

[.45Cole]

45 2.1 Thanks for the drawing, much better than my Paint abilities! (what is your radius on the ogive if you don't mind me asking)

Right now I'm up for anything that meets the above particulars. I would like to size to .454 for a pesky revolver, but the design should size down to .452 relatively well I think. Nobody else, or has there been a design which filled this niche before?

[Johnny_Cyclone]

I'd want the .190 Meplat, a crimp groove, and droping at .454 dia.

[M-Tecs]

Something like this would be nice. http://castboolits.gunloads.com/showthread.php?t=14268

M-Tecs,

That Warf73 454190 is nice,

I would like the meplat smaller in a 4cav solid version.

The HP molds with the reversible HP/FP pins could maybe make the meplat larger, but hey whatever works for the buy.


45 2.1's design

Full description.
The meplat is 0.225" and the crimp groove is set where it works best for accuracy. Weight is 253 gr. bare and the weight of my 454190 as cast is 254.6 gr., so it is a very close match when lube is applied. It's spec'd as 0.455" ... and a crimp-to-meplat length 0.314"....Warf73

...Meplat has been enlarged to just barely cover the primer pocket.
Lube grooves have been squared up.
Crimp groove has been added....Warf73

[Johnny_Cyclone]

..Bump.. because I want one.

Also wondering if the cherry could be orbited out to make a .460 dia version
for a 45/70 plinker boolit?

[BattleRife]

I know where there's a Rossi M92 carbine that might love this bullet. Colour me interested, especially in the crimp groove version shown in #8.

[Firebricker]

I'm real interested if 45 2.1s design is what the GB is for. FB

[.45Cole]

Well it sounds like crimp grooves (yea or nay) and perhaps some meplat diameters...other than that I think the snowflake is about snowpea diameter now. Any other contentions?

[Johnny_Cyclone]

last bump

[crash87]

Why the .190 meplat for this bullet? To me, this is the one dissadvantage of this bullet design.
This does make more sense....."Meplat has been enlarged to just barely cover the primer pocket". Also, IMO, the crimp groove, "with" the wider meplat makes this the perfect design for this bullet.

I don't think the meplat has to be all that big as long as it's flat. The cartridge primers in a rifle magazine tube are under less spring load than when being seated in a loading press.

I wouldn't think the recoil from a .45 Colt is going to knock a rifle around all that much to worry about it?

In revolvers it shouldn't matter at all.

I was just thinking a tad more aero and closer to the original nose profile than a big FN. Besides there are plenty of big fat flat nose moulds avalible.

Not many 454190's with a crimp groove though. That's the main thing.


Still,.. it's not a round nose or a pointy j-word, and .190 is bigger than the large primer punch on my reloading press.

I would think .190 would be fine. Has anyone tried it and had issues?

Just thinking.. how about this.. a mould for solids could have the .190, and if enough interest, the cramer HP version could be made with wide FN and HP pins..basiclly more nose designs from one cherry all in one GB?

.190 FN Solid mould
Crammer type mould with .225(+) FN, Round, and Penta pins

Wouldn't most who like a WFN also like a HP option, but those wanting a more aero streamlined boolit that's also somewhat easier loading (revolver cylinder, rifle loading gate) like the solid version?

I might buy both once FN/HP drawings are up.. lol

I see that using one cherry for both would shorten the nose length on the crammer version.. ruducing weight.. but if we scrap the whole .190 meplat and try to keep the same length for a WFN design... well, wouldn't that chage the ogive from original..454190?

Hey.. is .190 what the 190 in 454(190) is about?? .. lol

Were still in slow moving discussion stage and the whole .190 - .225 isn't a total deal breaker as it's just .035 ..but I'm gonna push for .190 while I can..

That .035 change could change the ogive profile if the boolit is left the same oal, or we keep the same ogive and lose length.. Hummm.

Crimp groove seems to be what everyone want's.

A nose of .190, .225. or maybe bigger for crammer are the ?'s

Let's here from more folks

The original Warf 454190 LEE Group Buy mold by 45 2.1 is a great design and produces a nice bullet ( I picked up a couple). Unfortunately for some that original dropped a VERY fat bullet. I would love to see a Mihec 4-cavity version that dropped at 0.455" !

454190 designed by 45 2.1

[jethunter]

I'd be in for a close copy of the original 454190 at .455" in a cramer or RG HP version. 454190 is a sweet bullet in revolver and rifle. Cast at 30-1 it shoots awfully well in the webley .455 revolvers too.

[Frozone]

GLL,
I agree and I'm in for a 4 cav that drops .455" in the Warf/45 2.1 design.
However, I'd like a solid option.
I just don't shoot hollow points.

[.45Cole]

I was hoping to get a solid/HP design Miha does by flipping the pins. I think that Johnny_Cyclone said it with a rounded profile and a .190" meplat. This gives it some punch, but it still flies well as it gets out there.

[45 2.1]

I've tried various things with this boolit design. I even know someone with a Lyman factory HP mold in it which I tried many years ago. Unless the boolit is dead soft, the small HP doesn't seem to open well unless driven past factory velocity. Rifle velocities did reasonably well. I also hollow based many of these. That did a lot for accuracy. Here is something to look at along that line.
