YES

The only small ring FN made was the 93, and Zastava didn't make any. Are you thinking of Large Rings like the FN commercial and it's clone made by Zastava? Those are 1.100"x12tpi

There were some "smaller" ring versions of the FN Supreme used by Browning for .308W-.243W rifles prior to buying Sako actions for medium cartridges. These are not plentiful, but, I have seen and handled about a half dozen over the years.

I don't know any specific dimensions, but, they seemed about the same as the early "roundtop" Brno 21/22 actions.

didn't Browning have a intermediate length small ring for their 243/308 made by FN for a very short time ?

Thanks Dewey

I have a Browning Safari .308 on an FN mauser action, and externally it does have a small ring receiver. I believe that they are std. large ring actions ground to Sm. ring contour, but I have also read somewhere that they are true small ring actions. I have not pulled the barrel to check, but I would love to know for sure.

I do know, however, that it is a std. length action, because I have 1909 botton metal on it.

I would think that you could remove the bolt and look at the right raceway in the front ring through the rear bridge.

If it is small ring/large thread the receiver would be pretty thin adjacent to the raceway(I believe).

But keep in mind, I rarely know what I am talking about......

The best known of the small ring 98 mausers is the G33/40, but others are the mexican model 1910 and 1935's, the ZF43? (not sure I have that one right) and I believe that there are others. These are true 98 mauser actions, but built with a smaller front receiver ring and barrel thread. I wouldn't try to make a full length H&H belted magnum cartridge fit, but for 2.5" belted magnum, 30/06, x57 mauser or 308 based cartridges they work well. They are great for lighter weight rifles as they are a half a pound lighter than the large ring actions, and the stock can also be slimmed for more weight reduction due to the actions smaller profile.

I don't know how accurate my postal scale is, but, several complete 1910 Mexican actions weighed 44 oz. As a comparison, the average weight of 10 complete standard length 98 mauser actions averaged 46 oz. The Turks averaged 47 oz.

As a further comparison, 1 example of a complete 1898 Krag action weighed 50 oz. and several comlete Winchester P14 Enfield actions weighed 55 oz.

I think that most of the weight savings in the small ring mausers is the ability to build a scaled down rifle like you pointed out.

Hi Jason,

I looked at the Browning .308, a G.33/40 and a 1909 Argentine. The receiver ring thickness at the extractor raceway looks to be the same on the Browning SR as it does on the G.33/40. But I am not sure that really is an indication of the barrel shank diameter. Looking on past the raceway at the portion of the barrel breech that shows at the 'C' ring extractor cut, the Browning shank looks like the 1909, and the G.33/40 shank looks smaller. So based on that, I would hazard a guess that it (the Browning .308) is a small ring (externally), large thread (internally) action. I wish that I could convince myself otherwise, though....
