Speaking of the 375 H&H, Ihave a Sako M75 stainless/synthetic and topped it off with a Zeiss 3x12x56 Diavari and am very pleased with it's accuracy....typically shoots 3/4" groups. I mentioned this because the M75's are being replaced with the newer M85 CF model and good deals can be had presently on them.

Recentlygot a 6.5x284 and havent fired a round through it yet and just ordered a Sako TRG 42 in 338 Lapua yesterday to play with. I have quite a few custom rifles but now pretty much only buy higher end factory guns due to not losing as much money on them if and when I get rid of them.
