For those of you in the know: I have a CBI 260 with the Match Throat. I am unable to load to the lands and fit within an AW mag. Obviously if I can't fit in an AW mag, it will not fit in an AI mag since the AW can load longer.

Question: Is the CBI 260 Match single load only with the 140 Amax at the lands?

If so, I'm planning to send my rifle to my smith and have him cut off an inch at the chamber end and reream with a standard 260 reamer that will allow me to load the 140 Amax at the lands and still fit in an AI mag (have 2 and kinda upsets me that I can't even use them). My accuracy with such a large jump (to be able to fit in an AW mag) isn't great. I'd like to tighten the groups quite a bit and loading to the lands seems to be one of several answers. Quite a few folks on other forums are loading to the lands and have great accuracy with Fed 210M/CCI BR and H4350.

Any thoughts would be much appreciated.
