250-310 grain roundflat .454 dia ?

[45 2.1]

I like my own. Since these are custom runs, they should be something that you can't already get.

[Willbird]

I really Like yours too 452...

Actually I went back and looked at it again, and must say I like it a LOT...the Keith types have an attraction (I'm an old guy, been shooting for 35 years) but as you say one can pick up a mold for them for novelty sake.

I think if we cross posted your bullet over on leverguns and some other places, we might get 100 (even if I have to take 75 myself hehe)

BUT, the 45-270-SAA is only available in a double cavity. RCBS does not even make 4 cavity molds (at least that I have been able to find). I would like a six cavity, which is NOT available except as a custom run. That was what I was trying to express in my earlier post. On the other hand, 45.2.1's design has GREAT merit and would be an excellent candidate for a custom run.

I want them ALL hehe

I like the design 45 2.1 posted. If someone decides to do a group buy, count me in. Ya'll are costing me a lot in moulds but I'm game for more. Keep 'em coming.

I'll keep my vote with 45 2.1's design.

Besides, has anybody considered that Lee may not be willing or able to produce a RCBS design? And, possibly RCBS might not like the idea of one of their designs being produced by a competitor.

Just something to think about.

45 2.1, what's the nose length and overall length of your bullet drawing? Estimated weight?

Nose to crimp groove = 0.340"
O.A.L. = 0.740"
About 265 to 275 gr. approx.

Did you do a volume density estimate on it?
I looked on Dan's website and it looks like a length of about .67" will give us 270gns
with .74" comeing in around 305gns.
I'll take some of my 340gn slugs and turn the base off to see what I come up with.
I do like the looks of your bullet though and think it will be a winner.

Frankly, I don't trust Dans figures. I use real bullets as comparisons. A 457191 comes in at 295 gr. and it is 0.782" long. The 454190 at 255 gr. is 0.692" long. The 454423 we just did is 240 gr. and its 0.648" long. A 452490 is 230 gr. and its 0.702" long. None of your or Dans figures fit in there on real bullets, do they? You do the math cosidering the grease grooves are larger than most of the others.

Lar45- I did some calculations and came out at 276 gr.

[J Miller]

45 2.1,

The bullet you have designed is exactly what I have been toying with designing myself. The only difference is I was aiming for 270-280 grs at .454" with 16-1 alloy with one large lube grove and a crimp grove. Also the flat nose would be very flat, not slightly domed like some bullets I've seen.

My thinking is a bullet that will seat out to an OAL of 1.60" so it can be used in all unaltered guns, lever and revolver. But with a large crisp meplat for a good smack 'em down for keeps hunting bullet.

I don't know if I could join a group buy right now, but let me know if it goes that far and I will try.

Perfectly flat will not drop out of the mold well, that is why they put a slight radius or angle on the end IMHO.

Bill

[lar45]

Lee asks for a 3 deg draft on the nose to help release I believe.

Does anyone have the density of WW handy?

If it's calculated at 276gns, that's close enough for me.
I just remember buying some molds that were guestimated and the actual weight came in about 20+gns heavier than expected.

for the 358-180 we did, I took the length from Dan's site and the finished product came in real close to 180gns.

[Cayoot]

Ok, I'm kinda confused (partly cuz I've been away on a new job so much that I haven't had time to keep up here, so today I'm kinda "Cram Reading" and I'm also partly confused cuz I'm just an accountant and we are always confused!)

But I figgure that you guys have always come up with great designs before and Wilbird steered me right on the Star Bullet Luber (thanks again), so count me in on what ever you guys decide.

[45 2.1]

45 2.1
I turned a bullet as close to your dimensions as I could get it. It weighs 277gns from WW.
Some minor concerns, the lube grooves look really DEEP. I'm wondering if this will cause problems with releaseing from the mold.
Glenn- the lube grooves are the same as the 454423 bullet that we just did and they drop out pretty well. You can ask the others about how theirs cast, but i'm satisfied with mine. The bullet is actually a copy of the Lyman 454190 I have that is the most accurate long range bullet I have that is modified in length some and has more lube capacity.

A 340gn mold that I have from Dan that shoots really well in my 454 has lube grooves that are .420".
I'm sure Dans bullet shoots well for you, but this is a different design.

I would personally prefer a meplat of between .32 and .36" instead of the .25"
The meplat is a direct copy of the Lyman 457191 bullet that has perform very well for me on game and target. The meplat is at 55%. I have had allot of trouble when using a meplat of 60% and above at lower velocities, they just don't shoot well at low velocities. This is mainly for the 45 colt. You have Dans bullet that shoots well for you, why not use that bullet for your hunting. Most folks here want it for plinking, deer, carbines and small game.

Thoughts?

I like it as is.
