pintoshot, After alot of load working, my best grouping with my Browning Micro Hunter is 42 gr of IMR 4064 behind a Hornady 139gr BTSP Interlock bullet and CCI Large Rifle primers. Now, I like Nosler bullets and use them exclusively in my .270, but the 140s don't shoot as well in my 7-08. (ps: and the Hornadys are about 1/2 the price of the Noslers and are very effective on deer sized critters).
