Excellent thread. I have rifles in 6 BR and 30 BR and own the reamers do my own work.

Reading this has me thinking of rebarreling my model 7 which is currently a 358 win. Could go either way but with more thought the 30 BR might get the nod. My reamer is throated for heavier bullets.

The current 30 BR has a 22" barrel and shoots 168s @ 2490 fps with IMR 8208 XBR. It is a SA Rem and the cartridges fit and feed fantastically. It also shoots 175 gr bullets @ 2385.

Fun to consider the possibilities.
