Do Ruger No1's still have long throated chambers?

[Canuck Bob]

Years ago Rugers No1s came with long throats and could load long heavy bullets without burying the bullet base deep in the chamber.

Is this still true among the 30 cals?

[Darrell Davis]

Afternoon Canuck Bob,

Hope we all get the answer to your question, as I can only speak from my current RUGER #1-s in 45/70.

All other #1s I have had over the years, had long throats.

However, the current rifle, a 45/70 has a VERY!!!!!!!  short throat.  To the point I could not chamber a Remington factory round.

I will be casting for my hunting bullets, so will just plan around this, but if I was buying factory ammo or bullets, I would probably have the throat opened up just a little bit.

The 300 Win Mag I gave to my son, allowed the seating of a 200gr Nosler Partition WAY!! out! 

Keep em coming!

I almost replied to this, but thought I would see what others said first, but did not want to confuse the situation since 30 cal was ask specifically.  But my 45-70 is a very short throat.  My .270 I do not know I have not used any long bullets or seated them long.

I cannot point you to where but I am remembering Ruger cured this in the early 1990's

My #1 in 45/70 has a VERY short throat, so short that I now only load Speer 350gr SPs.  It would push Hornady 350gr FPs back into the case past the cannular(sp?) However, in my #1 in 35Whalen, I can load any bullet pretty much out to the end of the case neck, even 250gr RN.  Go figure,

Ditto  on the short throat on my #1 in 45/70. Frank

April 2010, Purchaced a No.1S in 9.3X74R. Throat length .210". not necessarily cured in this cartridge for this particular rifle. Can't comment on the .30's. Crash87

Hairtrigger -----------------------

Not sure what direction the "cured" comment is pointed.

Is it toward the loooong throats?

This is of course, just IMHO, but personally never had a problem with the long throats.

On the 300, it allowed the long 200gr Nosler Partition to be seated long and therefore not enroach on powder capacity.

On tiny bullets like those found in my 22-250 and 223, I didn't have any grouping problems, so am guessing whatever the length of the throat it must have been OK.

On my 45/70, I may need to have the throat opened up a bit.  That will depend on how my, hopefully soon arriving LBT mold makes the 350gr WFN bullets.

The RCBS 405 mold - casts out about 428gr - are OK, but the one factory Rem I found wouldn't chamber.

A forum friend sent me some of what he calls "Mastodon Flatteners" which weight in at about 540gr.+/- which sad to say I can't chamber.

The new LBT mold was ordered as part of a group buy, so I was not dealing directly with Veral Smith on the order.

Veral is very much in the know on molds, mold design and fitting molds/bullets to rifles, so in the order sent in, I indicated the #1 had a VERY short throat and expect things will be just fine.

However, all in all, I would just as soon that the #1 throats remain on the long side as in times past as they never cause me any problems in 7mm Rem. mag, 300 Win. mag, 223, 22/250, 270 or any others which may have passed my way.

Yep, love those #1's!

Keep em coming!

All of the complaints I hear are for pre 1990 rifles... more or less

[Darrell Davis]

All of my #1's, with the possible exception of my 45/70 were pre 1990 and every one was very good.

I have a pair of Rugers, both in 270 WIN.

The first is a late 70's M77.  That one has the long throat.  The second is a mid to late 90's #1b.  I wouldn't call the 1b throat short, just nowhere near as long as one in the older M77.

For what it's worth, my 375H&H has no problem with 300 gr round nose seated long over a packed case.

[Darrell Davis]

Started to load boolits, last Monday, from my new 350gr LBT mold, and they won't chamber.

I have already contacted my Gsmith and hope to get with him next Monday to slightly open up the throat on the 45/70.

Not sure I get the point of decreasing the throat to this point.

I have no plans to be shooting "J" bullets, but had one factory Rem. round I picked up someplace and it wouldn't chamber.

Seems the reduction in throat depth to this degree, for whatever reason, was a bit of over kill.

Not a real big thing to have the throat opened up, but not something that seems reasonable just to shoot normal ammo.

Anyway, love those #1s, so will "get er done" and go on from there.

Keep em coming!

My '92 RSI in 7x57 seems to have a long throat although I don't reload the long 175 grain bullets that would require a long throat.  However, I do seat the 150 grain squared-based Sierra ProHunter bullet I use for practice and for my accuracy loads 'way out to get the bullet within 10/1000ths of an inch of the lands and grooves.  Naturally, this makes the overall cartridge length greater than standard.

Looking at the loaded round, it's obvious the 150 grain Sierra is seated out considerably further than normal because there's only about 1 caliber (.284") of the bullet still being held by the mouth of the neck.  However, because the rifle is a single shot, there's no magazine holding rounds which could allow loosely-held bullets to be pushed back into the case due to recoil.

Therefore, no harm, no foul.   


Strength & Honor...
