The #1 selling Dead Center for 1-28" twist rifles like yours is the 40/50 200 grain. Precision Bullets is now selling them for 57 cents apiece "delivered" with 240-pk bullet purchase until the end of the year.

I am looking real hard at purchasing either the 275 gr.Keith Nose or 240 gr. Extreme Elites in 240 pk.TheExtreme Elitesarearound 37cents "delivered". That's a "Best Buy" bulk bullet price anywhere you shop when you consider that the Extreme Elites are the Dead Centers without the poly-tip.
