Been there and done that and I'm afraid it just isn't for me...
Bought a 6" Freedom Arms .475 and fed it a reduced load of 330, 400 and 420 grain bullets that were in the 1050-1100 fps range...and it just wasn't fun...so down the load it went.
Killed me to do so as it had THE tightest test target group for any FA I have ever seen...
...and it shot great...
...but just wasn't me...
Just going to stick with my whimppy little .41s....
