Been gone a while. Yes, I really like the .475 275 gr. Xs in my FA. Done around 10 groundhogs and 10 deer with them in addition to the Cape buff.
I started using this bullet because 325 & 400 Horn XTPs, and 325 & 400 gr. Gold Dots act exactly like FMJ bullets. Groundhogs moved a little. Deer ran a lot. Actually lost one to a 400 Gold Dot on a decent hit, but she ran to a WV jungle and never found it. Internal damage was minimal, exits were tiny.
When I saw the large hollow cavity on the X I knew it would probably be a winner. Never had a groundhog move from a hit. Farthest a deer ran was 3 or 4 yds. Most were slammed to the ground.
My PH didn't object to me using on a cow buff, a pretty big one. She bucked at the shot and ran about 200 yds. and died. SEcond shot not needed. There was complete penetration on a rear lung shot (I pulled it a little). Good internal bleeding with a 3+" area of damage through the buff.
Another bonus to the 275 is by being lighter its recoil is much less than the 400s. Good for old, arthritis hands.
By the way, cast bullets act just like FMJs in deer, BUT they do create just a little more damage. I killed a very large water buff with a 400 cast with one, although my guide had me put a "finisher" in the dead buff.
Funny, the few TV shows I see about Cape buff say how tough they are requiring multiple shots. I've killed 3 plus the water buff. One broadside at 35 yds. with a .416 Taylor Encore and old Horn. 400 gr. SP, ran 15 yds.- 1 shot. One facing me at 80 yds. with the .416 Taylor and the newer 400 gr. Horn. DG-X. Hit him just below the chin, dropped and dead. Bullet expanded like the pics and penetrated 2/3 the way to the back- 1 shot! And the cow buff- 1 shot.
Maybe these rifle guys ought to switch to a handgun
...or shoot better.
Accuracy? I use a Ultra Dot now. 1 1/2" at 50, 4-5" at 100. A scope should improve this, but that's not what the .475 was meant for.
