DoubleTap Ammunition
My regular dealer is out and has been for a year, so it is either really overpriced stuff on gunbroker, Remington 210gr semi-jacket soft point for $50.00 per 50 (when you can find it at cabelas or bass pro shops), or Buffalo Bore (really expensive)...or this may be your call to begin reloading...I know that I need to get rolling on it, I have a pile of brass, just need to build myself a bench.
Good luck with the search...if you have brass to reload, I do have a source (commercial loader) that will re-load your used brass and ship it back to you, just FWIW.
