Can you except any kind accuracy with cast bullets from a non throated chamber?
I just had a 32-40 chambered but no one around here has a 32 throat reamer, so I was going to try some bsing and fixed loads, but that it may be worthless.
Remakes please....

I think it depends on how you define accuracy.  The Browning 1885 rifles in .45-70 have won their share of Silhouette matches and they have zero freebore.  Dan Theodore has been advocating zero freebore chambers for long range black powder shooting using bullets designed to seat well into the bore.  Several shooters have been doing quite well with them.   They do work quite well if paper patched bullets are your thing.

Throating is absolutely not needed to get accuracy when breech seating. All that is required is to have a mold made that has the front few bands bore riding (I like .002 to .004 over bore dia.) This is not a big deal and keeps you from having to alter a rifle- which, if it is an original, is a big deal. Now that I have said that I will add that you may be able to breech seat regular cylindrical bullets in a chamber not set up with a special throat with a mechanical breech seater and get good accuracy. (My most accurate rifle(has shot 250s) is set up like this)You just need to try and see. This will be harder to decide if you have little experience shooting breech seated bullets because there is a tendency to blame equipment for shortcomings which are the shooters.

oh, i have been shooting schuetzen matches for the last 4 years and the other 3 guns that i have had throats cut for tapered bullets. This will be my wifes CPA 32-40 I do have a Weber seater so the tapered bullets that I do have will go in but there is a share start to the rifling, i was just concerned that the bullet was being deformed but the sharp rifling at the start of the chamber.
So that is where I am right now.

Jack, beats me...

Lister to Quarter Bore he knows what he is talking about. A few issues ago I reprinted an article that Ken wrote on the  proper fitting of a bullet to the chamber that you have. I felt that it was an important article and enough years had passed that there was a whole new audience that didn't have the information. Look that article up there are more bullet styles than just cylindrical and tapered.

People have been BSing the standard 32/40 chamber for over 100 years with tapered and two diameter bullets such as the Ideal 319289 mold. The throat on the standard 32/40 starts at the front of the neck area of the chamber and tapers from there on through the rifling at 21.5 deg (the 30/30 tapers at 15 deg in the same way). There is also the Shuetzen chamber that tapers from the base of the case to the mouth w/o a neck at all. In that case the throat maybe almost anything as there is no standard for it but, as Ken says, it should not be 90 deg and I would guess that 30 deg would be the steepest angle for it.

A tapered bullet will BS fine with in that throat if it is .316-.317 on the first band and no larger that .321 on the base, a fairly standard design. I don't own a 319289 but, that two diameter bullet is approx. .315-.316 on the nose bands and .320-.321 on the two base bands and it has been used to BS the standard chamber for over 100 years.

With the above bullets and throats, you should be able to shoot 245's at times and groups under 2.5" if the fit is right.
