460 Buffalo Bore Problems

[buck460XVR]

My PC compensated Hunter will shoot factory Hornady's just fine....cases slide right out.

In my handloads I have found that it don't take much of a increase in powders sometimes to go from easy extraction to sticky cases...and generally there's flattened primers to go with it. I have also found that many times, it don't take much over starting loads to get to this point. Whether it's the longer barrel, tighter throats or some other reason, I don't know. I reload now like I always did, for all my other revolvers..... when cases start stickin', it's time to drop the load a tick. The .460 has enough power with standard loads, I feel one doesn't need to load it hot.

Indeed, call Buffalo Bore

I know this. I am a die hard .45 Colt fan. I was having a case of severe brain fade I guess. I corrected it in my post before I saw your response. Good catch though.


To the OP, as I posted in the other thread you started, get those chamber throats corrected! I once sold one of the nicest and most wanted (by me) Smith 29's because of this. I had no idea back then that a famous gun company could, or would, do something so stupid as turning out guns with improper sized throats. That will skyrocket pressures in even the .44 at 36,000 PSI, it'll really have an effect on the .460 at 65,000 PSI. FWIW

At least now I know I'm not the only one flattening some primers on my hand-loads. I used the lowest Grains of Blue Dot, Win 296, H 110 with New Starline cases and 200 grn FTX and all I experienced was a Big Bang and flattened primers. Still I need to call Hornady to see what they say (maybe they'll say go lighter). I'm using 460 XVR 8 3/8"


Dec 17, 2009>>>>>Called Hornady and asked them about my flattened primers and their good tech guy reassured me that if all I had was flattened primers (not cratered) that with these high pressures it's not a problem.

I used Hornady's Data for the 200 gn FTX >>> Win 296 @ 43.3gn, H110 @44.6 gn, Blue Dot @ 48gn. I was using New Starline Cases and Winchester WLR Primers

I shot 5 of each and all had the same flattened primers everything else was normal (cases fell out no problem).

The ambient temp. was 90 degrees F.

I'm happy with how they shot and Hornady's patient Tech's
