475 A&M Magnum

Hello, we are looking for some input as to the best twist for a 475 A&M magnum, would like to hear from owners of this caliber as to their experiences...

You should expect velocity to be around the same as the 460wby 2500-2600fps

Hi Gents
A 1 in 14 twist works well for .475 and a 500 grain bullet. I shoot them in my 470 Mbogo and have had very good results. I met you guys down at SCI and I think I left a 470 Mbogo cartridge with you. It has more case capacity than the 475 A&M and is beltless. The 1 in 14 twist will stabalize the 500 grain Barnes X which I think is about the longest .475 bullet around. I have some 560 grain GS custom solids but I haven't worked up any loads yet.

Take good care,
470 Mbogo

The 470 MBOGO is a better cartridge than the 475 A&M. 1:14 seems to work fine in mine.-Rob

Hi we still have that cartridge, and it probably is better, but the customer wants the A&M so guess what hes getting [Smile]
