I just chambered my first 9.3 X 62 today and fitted the barrel to a K. Kales Mauser action.
Holy tamole.....that chamber reamer has about 1/2" of freebore.....is this the norm for that round?

Vapodog , my 1940 husqvarna m146 9.3x57 has a very loooong throught. 286 gr bullets barely seated into the neck just to hold them have a long way to go before they would touch the lands.
That 1/2" might be shorter...?

The guys at the swede forum all have the same long throats in their 9.3's Husqvarnas

You're supposed to check this out before the reamer goes in the barrel.
Just lay a loaded cartridge next to the reamer.

AAhhhhh.....wellllll...I did.....that's how I know that there is a lot of freebore!

A lot of European rounds traditionally come with a lot of freebore - a pain in the neck that can be.

I have noticed that reloading data for the 9.3 X 62 often is a bit favorable to the .35 Whelen and often wondered how this could be.......and it now appears as though the extra freebore just might be the answer!

If this is true, then the answer to the Whelen crowd trying to puch the envelope on their guns is simply to increase the throat length.....possibly this is where Weatherby got the idea.....?

The 9.3x62 has also been improved, the shoulder is expanded and further forward.

Seat the bullets out to the end of your magazine and you can get some mighty good velocity from that 9.3x52, all mine are done like that and I even open the magazine a bit.

I order all of my reamers with no throat and cut the throat to fit a specific round.

When I bought my .223 reamer several years ago, I did have it set with a throat for 40 gr. bullets. That way it would work for the shortest bullets (the ones I planned on using) and could cut a longer throat for other jobs requiring heavier bullets.

This plan is also a sound one, but the 2 reamers I order last week will be ground sans throat, with the proper throating reamers ordered at the same time

In big bores I like the long throats and I have found that a bullet jump is normally not concusive to inaccuracy as many claim, at least that has not been my experience in big bores. I like a big bore to shoot and inch at 100 yds with a scope off a bench and if it won't I will not have it. I will rebarrel or do whatever I have to do to correct it...

A long throat may make a difference in target or varmint rifles. My 6x45 does not seem to be bothered by its long but not excessive throat in that it shoots .294 average with 60 gr. Sierras and 1.5 with 75 gr. Barnes X and thats acceptable as I use the Barnes X for deer and antelope, but I credit that differnce to twist.

I have reached no real conclusion as to the long throat controvercy, I think it has more to do with the rifle itself, some will and some won't is my guess.
