The 45-100

[Old Jim]

With all the talk about 44-77s, 45-70s, 40-65s, 45-90s and the 45-110, what happened to the 45-100?

Anyone shoot one enough to tell us all about the cartridge and its loads?

Inquiring old mind,

Jim

I'd be interested also Jim. It gets referred to every now and again but with the multitude of projectile options now...both gg and pp that allow seating well out of the case in a 45 x 2.4", I guess its not the 'go to' cartridge it may have been. With no 44 bottlneck option ( courtesy of rim diameter I believe ) for the #77, I was considering this cartridge with a snug chamber and 7 degree leade as my choice if ( read when ) I go that route. Standing by ??

Jim you forgot the .44-100 2.6 straight I shoot one of those and I don't think I would trade it for the .45-2.6. Maybe Bryan Youngberg will comment, he shoots quite well using his.

I've seen Bryan and Jimbo do some pretty awesome shooting at long range with their Shiloh .45-100's. Seems like a good cartridge if you want a little more muzzle velocity. Brass is pretty easy to get too.

Please, give us more details about this round.
What load do you run?

Gary lets let Jim get his answers form guys that shoot the .45-100 first then I will reply about the .44-100 Rem st.

jim,
you give the 45/2.6" case its correct nomenclature when you add the number 100.
the 45/2.4" case was also 45/100. not as it is so often called today the 45/90.
the 2.6" case came first, with the intent to use what was considered the ideal charge of 100 gns .
it was soon discovered that the more bullet in the barrel and the less in the case, the better the accuracy.
shortening the 2.6" case to 2.4" allowed 100 gns to fit with a bullet barely in the case, same cartridge overall length.
of course a natural progression from this would have been to seat the bullet right out of the case as in breech seating.
once breech seating became popular, people wanted more, and went back to the 2.6" case, droptubing it full with 112 to 115 gns of powder and about a 1/8" gap between the base of the bullet and the wad level with the top of the neck.
such ammo was shot up until about 1912 at sea girt range.
which leaves the 2 7/8 case.
it was only ever loaded with 110 gns with a really light bullet, totally unsuited to most uses.
in fact it was the only 45/90 sharps cartridge when loaded with sensible bullets.
the shallow seating of the 2.4" case for target use was great in that application, but totally unsuited to hunting.
the 2 7/8" case would run 90 to 100 gns of powder with deep seated mostly 500 gn bullets, and cartridge overall length was usually less the the 2.4" case loaded with a 550 gn long range bullet.
with regards modern cases, which are thicker than the old balloon head ones, fired 2.4" cases will take 100 gns of swiss 1.5 or 1.0 droptubed, and then a thin was as well.
compress this about 1/10" or 1/8" and you have a good pp load. or just leave the charge as is and breech seat the bullet.
the 2.6" case will take more loaded similarly.
modern users of the 2.6" I believe include dave gullo. this could be open to correction.

keep safe,
bruce.

Thanks to those that replied. I may ream a 45-70 to the "100" some day.

I've got a Wesson #1 in 45 2.6 but haven't gotten a chance to work up a load for it yet. Maybe this fall when the works all done.

Jim-IF the .45-70 barrel shoots good. LEAVE IT ALONE
Have a barrel made up in .45-100.
