Not really an oddball but one that while it is respected by a few is ignored by most of the averaged shooter. That cartidge is the 7x57 Mauser, disliked because factory ammo is underloaded for several reasons and loading manuals don't give full power level loads. One weak early model rifles like 93 and 95 Mausers or two, the Remington rolling blocks. Another factor is while many have the original long throat designed for the 175 gr. bullet, some companies and custom builders used shorter throats for customer only wanting to shoot lighter weight bullets.
The 7x57 can be loaded in a modern rifle to standards that snap at the heels of the .270 Win.and .280 Remington without straining the action.
Nosler manuals show loads that have higher pressure and I understand the new Speer manual had some spiffy loads for the cartridge. I've got to get the new Speer manual when I get the chance. I do like what I'm getting with Re17 and the 150 gr. Nosler Partition. Great speed, excellent accuracy and case life is great. Nine loadings so far and primer pockets are still tight.
