Recommendation for for 45-90 elk boolit

[HighUintas]

Here is what I have:

A 24-in barrel 45-90 and black powder. For bullets, I currently have some Missouri bullet company Buffalo number one bullets reported to be hardball alloy at 18 bhn that I have re-lubed with modified emmerts. I also have some 457193 bullets that I believe are between 9 and 12 bhn.

I am the type of hunter who doesn't take a shot on an elk that's anything other than broadside or slightly quartering.

Given that information, what would the impact velocity limitations be for these two bullets? Also, what is the bullet weight limitation for this type of shot on an elk? Would the original 300 grain Express bullet work with this type of shot and what would the velocity limitation on that bullet be if it were one of the same two hardnesses that I have listed above for the other bullets?

You may find the hardball alloy to hard for best accuracy. I would go with the 9-12 bhn bullets they should work fine. A 300 grn bullet at 1300-1400 fps should do a great job.

Another route to go is the old Buffalo hunters paper patched bullet cast from very soft lead. I cast mine in a brooks adjustable mould at 530 grns in 20-1 lead tin. 2 wraps of cole paper the soft bullet never touches the bore so no leading. From my 45-90s 34" barrel at 1200 fps, recovered from the 200 yd sand backstop with about .150 of the base intact and the nose is mushroomed to around 1" in diameter atoll weighing around 510 grns

Are you talking about a bullet for an 1886 or a Sharps? For my Sharps I use an NEI, 480 gr. cast bullet. It looks a lot like an elongated KTSWC. For an '86 I suspect you're going to be limited by action length.

[HighUintas]

Thanks both for the help!

Yes I'm shooting an 1886. I've never heard of anyone shooting a PP bullet out of a lever but I guess a guy could single shot it!

I was primarily wondering because I have seen the Lyman 457122 for sale a few times (I don't cast anything yet) and I like the idea of shooting that for regular fun and saving my precious WW, but also wonder if that bullet would be sufficient out to 200yd with BP on an elk.

[sharps4590]

I'm not familiar with Lyman's 457122 but I do have the 193 mold. I killed a few deer and hogs with it before I acquired the NEI mold and had nothing but good results. Nothing like the bang/flops of 480 NEI but never had anything go very far. If the 122 is the 300 gr. bullet, I'd go with the 193 every time. It will have better sectional density and though the 300 gr. bullet will start out faster, the 405-420 gr. bullet will retain both velocity and energy longer. And I admit, I am not a fan of light for caliber bullets.

As far as the ballistics, they will be in almost any loading manual.

In real life thousands x thousands of Buff and other critters have been well thwaped with 45 Caliber cast no harder than 40-1 up to range scrap using BP.
If you smack any elk with a 400 or heavier soft cast in the lung / heart zone it will expire. If I could I would also want to punch a shoulder or front leg just to immobilize that big critter if you are in the hills or thick pines.
Last elk my son shot was at 300 yards with a lowly 180 grainer from our 30-06. Through both lungs. Big cow half trotted 50 yards, spun 3 times and dropped. A 400 grain caliber .45 would have done the same.

I use the Gould 330gr Express HP bullet over a case full of compressed FFG powder. It is the Lyman mold 457122SC. Cast at 20:1 and driven to 1600 fps, it expands beautifully.

Yes, it is the 330 grain hollow point bullet. The slightly lighter weight hollow point is something I wasn't sure about for a thick skinned elk.

[waksupi]

I would not use a 300 gr. bullet for elk. The old express rifles had a lot of failure, due to insufficient penetration. The old 405 gr. Government would be my first choice. They kill elk dead.

Well hmmmm

Shot placement is half the equation.

Having been an elk hunter for about 60 years and having taken a fair number of them I have some thoughts on what constitutes an elk rifle and the proper bullet. First, depending on the rifling twist of your 86 you may have to use a lighter "express bullet" in order to stabilize it. I like to use bullets that are on the heavier side for the caliber, especially on elk, as I want penetration. In my experience I get a much better blood trail when I get an exit wound. With the Lyman Great Plains style cast bullet of about 400 grains from my 50 caliber muzzleloader using 100 to 120 grains of 2 F black I've only had one pass through and that was a neck shot. Bullet placement is critical but, perfect placement isn't always what we get under field conditions. The one shot dead right there shot is rare even with my 375 H&H. So again I'll just say I want complete penetration and heavy for caliber bullets generally give me that. Of course your mileage may vary. Good luck follows those who are prepared. Hope you get an elk.

Mine is a new manufacturer rifle, so the twist is a 20. I have an accurate load with the Missouri bullet company 405 grain bullets I mentioned in my first post. So if need be, I can definitely use that but was wondering about the max range of that bullet given a certain velocity.that load has a muzzle velocity of just under 1500 feet per second.

I agree on sectional density and penetration being important. In my '06 I like to use the regular cup and core bullets, but go heavy for caliber and not push them too fast. That seems to give a very good mushroom and penetration on elk. This being my first go around with large bore cast bullets though, I'm still trying to learn about the heavier bullets ability to penetrate. I haven't been able to find any information on whether you get generally the same amount of penetration for a given sectional density throughout all different caliber bullets, or if you would tend to get more penetration from a larger caliber bullet of a given sectional density. I was thinking the latter might be true, but not sure.

I don't think I'm in a position to actually get a mold and pot yet, so maybe I'll get some lighter and heavier bullets on my next order and do some testing

The 405 grain military load in 45/70 would go through a buffalo at 500 yards.

Well maybe I'll get the Gould express 457122 mold to shoot for fun to save lead, and just buy some commercial 405gr bullets.

Any suggestions on the highest quality 405gr bullets?

I was thinking about ordering some more MBC buffalo #1 in their softer alloy, but the box that I have has way too many culls in it from air holes near the surface and slag sticking to the bottom edges. Do people usually have better luck with MBC or should I look elsewhere for higher quality consistency?

I've shot quite a few of the 330 grain Goulds hollow point in 45-70 rifles and they worked well but, I never shot any game with them. Another less expensive option would be the Lee 340 grain RNFP. Right now moulds of any description are hard to find. The only commercial cast rifle bullets I've tried were the "Oregon Trail laser cast" 45 caliber, 350 grain, RNFP, plain base. They're harder than the proverbial woodpecker lips, so you won't get any expansion, but they are very accurate in my 500-450 double at about 1900 fps. I know they make a 405 grain, 45 caliber bullet as well. I haven't bought any of the Oregon Train bullets in a few years but I assume they are still in business as they still have a web site.

Buffalo Bore loads cast bullets, see their choices, then match their velocity in your 45-90. As for bullet placement, buy a copy of Craig Boddington's "The Perfect Shot, North America" (I think Amazon sells it).

Shot placement is half the equation.

True, but it’s the bigger half.

My dad used the Gould 330HP/457122 in 45-70 (1886 smokeless) for all of his elk hunting and never had a problem (he always took neck shots no matter what caliber). The Gould was the go to 45-70 hunting bullet of the past and I see no reason why it wouldn't perform in the 45-90. Keep in mind that at BP velocities the 45-70 or 45-90 isn't all that flat shooting out to 200 yards so be prepared to make appropriate sighting adjustments over that distance. I have dad's molds to include the 457193 and 457122, as well as the Lee 405HB and 340FP, all shoot great in my original 1886 45-70s and all would be adequate for elk at appropriate distances.

Your second question was a recommendation for best quality 405 grain bullets. I shoot mostly my own cast bullets but I do like Lasercast as well in a variety (to include .45) of calibers, however if you are shooting BP I would look for a 405 with appropriate BP lube (Montana Precision Swaging and probably others). For smokeless loads I think you will find most of the commercial cast bullets will be just fine, BP loads will require an appropriate BP lube (SPG most common).
