Deep throat?

I have been shooting my 94 Winchester 32 win spec.  Using a Lee 8mm mold and a Lyman 323470 that I have to load all the way to the bottom of the neck and I still run up against the lands.  I recently purchased a Ranch dog outdoors flatnose for the 32 spec. thinking it would start tapering right above the crimp groove, but alas it doesn't and it really runs up against the lands.

20+ years ago when I was paying attention to this type of thing, cast bullet shooters were talking about extending the throat?, chamber? whatever the correct term is to facilitate a better fit for their bullets.  Is this a viable alternative? will I ruin the rifle for anything but cast?

The Lee and Lyman bullets shoot pretty good but bolt closing is a little tough, The ranchdog that casts really nice looking bullets tends to shove the bullet deeper into the case.

Any information would be appreciated.

will I ruin the rifle for anything but cast? Short answer, no. There are some magnum rifles that use a bit of “freebore” before the slug encounters rifling to help keep pressures lower in chamber.

You probably want to make several dummy rounds with the bullet seated the length you use and take them to a 'smith and have him ream it to fit so the slug just kisses the start of rifling.

Thanks for the info Fred. I turned some of the ranch dog bullets over and sized the nose to .311 down to the crimp groove and loaded with 19gr of 4198. They chambered with a little extra force and gave me 2” groups at 50yds which may be as good as it will do with my poor eyeshight.

Something doesn't sound right. The 32 Special should have a .315 bore. If you're sizing the nose to .311 and they still chamber hard, I'd talk to Veral Smith at LBT Molds and slug the throat before you do any machine work to it.

I did the same with an 8mm lyman lovern style mold and they chamber even easier, but still engraved by the lands a bit. Thanks for the bore diameter Bill, I didn't know that. The little bit of factory stuff I've shot seems not to be a problem. If my groups continue to improve I may not worry about machining anything. Wish the weather would improve, this wuldn't take so long.

I shot a 3P rimfire match weekend before last and the winds were blowing 7-19MPH, gusts up to 25, and the wind would switch from 4:00 to 9:00. Not exactly a stellar day, but a bad day at the range is still better than a good day at work! You guys probably still have freezing weather, I'd bet.

29 this AM, but calm winds so I think I will take the 6 rounds I have loaded up and see how I do. Might as well take my Yugo Mauser and empty some more S&B rounds for the brass, wanna turn that into a cast bullet shooter too.

There is an easier way to get any cb to fit in your throat. That is with a taper die, knocking down the nose and drive bands of the cb kind of like you were doing loading the cb nose first into a sizing die.

I think if you do a search on taper dies you will find more info about them. I also think there is somebody now offering to make them for sale?. I taper many bullets to fit better in the throat and load out further in the neck................DanW

I took the six Lovern style loads with the sized noses along with some that weren't sized to the range. With 19grs of4198 I was getting 5 shot groups just under 2” @ 50yds with most groups giving 1” 4 shot groups. At 100yds with a really big target I got a 3.25” group and ran out of bullets. With better eyesight I think I could shrink that down some.

Dan thanks for the heads up. I wonder if I should bother or just practice trying to get a better sight picture.

Deep throat can mean a several things. Let's assume it means wobbly bullets.
