Home Forums Hunting & Shooting BPCR 45-70 vs 45-90, -100, -110, ets

how dare you question the great expert of all things BPCR!

As we say in aviation, he has stupid set the "ripple fire". Aside from being a dorky looking buffoon, he's an unmitigated ASS and a self admitted troll.

I designed my .45-2.6-550 (.45 100) reamer to provide LOTS of Tight .459" freebore.
Freshly cut, that section requires a little finish lapping, and than a sniff of longitudinal lapping. The Reamer was DESIGNED to cut a chamber that would run well with a Leeth "Gordon" Greaser, the Jones' Creedmoore, and others of that type.
This chambering can be loaded from Normal BP .45-70 energies up to a pretty exciting reverse duplex ".45-135-550" spec (requires 2 compression) that is pretty doggone rowdy. We've never chronographed that load, It's an offhand only stunt, I AIN'T shooting it of a bench.

Did the same basic freebore set up with my .45-70 reamer, it's a versatile chamber to load for, as well, and can handle .45-83 loadings, when a fixed round breech seater is used.

For dangerous game I'd damn sure want that .45-2.6, it would no doubt have an edge on the shorter case.

Would nonetheless advise you to start with a well built .45-70, Se�or.

Yeah, really,......nothing quite as deadly accurate as .200" of .4810"+ "Freebore" to properly 'Slug up' a CB,.....prior to it being immediately slammed back to .4595".

Great for the necks of those cases , to.

GTC

Duh!

Thanks for the correction, Crossfire.

It works fine in mine. If you ever shot, you'd know I'm right.

From the Shiloh Sharps web site forum discussion:




"You can physically fire a .45-70 in one of the longer .45 chambers, but it strikes me as very poor practice.

Most of us who purchase these rifles work hard to get the accuracy of which they are capable, going through a great deal of effort to cast perfect bullets, size and lube them properly, find the primers, powder type and charge, and overall length that the rifle likes. We get a lot of enjoyment out of getting all we can out of these fine rifles.

What you can expect when shooting a .45-70 in a longer case is probably very poor accuracy, since the bullet will bounce around the chamber for 0.30-0.775" before slamming into the front of the chamber and the rifling at random angles. That will probably result in leading in addition to non-existent accuracy. I'm not sure whether there would be physical damage.

With lead bullets, you may not foul up the chamber, but why anyone would bother to do something so sloppy and so obviously poor in practice is beyond me.

It's like buying a Ferrari and using standard grade fuel. You can do it, the engine will probably run, and you may or may not have long-term damage. But you can bet that there will probably be pre-ignition that can be very detrimental to engine life, particularly if you use the engine like a Ferrari is meant to be driven.

The difference in cost is insignificant-probably $50 or less for cases to do it correctly. In my non-so-humble opinion, if you want minimal effort, either get a .45-70 or stick to the kind of rifles you can buy at Wally World."




Now, to his credit, Swampy never said they were accurate or they didn't make a big mess...

Or, another way to look at it, without much expectation, there can be little disappointment...

DF

It must work for him as they all seem to go in the same hole!

You mean that off the back porch target with powder burns...

DF

They have been accurate....I shoot .38 Specials in my .357 Magnum too.

And I've shot 44 specials in my 44 mag..apples and oranges compared to what you're doing...

He's DEFINING clueless more clearly. with every post.

....and this idiot claims to be an " instructor " ?

Good Grief, Charie Brown

GTC

It's exactly the same thing.

As noted, you don't know the ACTUAL chamber specifications of the chambers discussed from your chamber pot.

"It's exactly the same thing"

Your a [bleep] idiot

GTC

Except...!

It's NOT exactly or even close to the same...!

Now listen up...!

Gonna make it as simple as possible...!

The .45-70 may look like a straight wall case, like .44 Mag/spec cases.

But it is NOT...

It's actually a tapered case with a neck and neck sizing dies can be had. No neck sizing dies for .44 Mag/spec.

Why?

Because, they're straight walled cases.

To summarize: .45-70 and its longer cousins are NOT straight walled cases...!

Don't believe me. Check it out on line.

DF

I've been aware of that since the 1970s. It's pretty much a non-issue.

If you're aware and have been aware (since the '70's) that these are tapered cartridge cases, what trips your wire to make a statement that they're the "same" as straight walled cases when you've just admitted you know that's not true?

I've got to be careful here. You're going to have me thinking and writing in circles just like you...

Wow!

DF

They work the same. The powder ignites and the bullet travels down the bore and the bullet strikes in the same place. The short jump isn't an issue at least on target paper. The taper is almost nothing in that few thousandths that the bullet jumps. It's still in the case when it engages the rifling.
