Reloading is the cheap way out. Easy to neck up 8x57s.
Load data available in Big Bore Cartridges from Wolfe publishing.
http://www.riflemagazine.com/catalog/detail.cfm?productid=76&subcategoryid=8Slug the bore as most will work fine with standard cup and core 35 caliber bullets.
Here is some data from another site:
"9X57 is a much lower pressure rating than the .35 Whelen.... CIP's rating is 2800 bar (40 500 PSI).
250 grains / H4895 (AR2206) / 45 grains / 2250 fps
250 grains / Varget (AR2208) / 49 grains / 2250 fps
280 grains / H4895 (AR2206) / 41.50 grains / 2100 fps
280 grains / Varget (AR2208) / 45 grains / 2100 fps"
It's also a great cast bullet cartridge as a long heavy slug
+-300 gr can be pushed as fast a lead can (+-2000 fps) and will penetrate for a day and a half. We have had excellent results in our single shot based on the so called Mauser 88 (really the Commission rifle) with NEI mold 358-268-GC-DD
