I have a S&W 14 inch .460 revolver and I have a couple of questions for anyone who can help:

1. What should the velocity be for a 200 grain Barnes XPB bullet with a starting load of 45 grains of H110 powder? All the info I can find talks about an 8 3/8 inch gun giving around 2200 FPS with this load. I am getting 2130 to 2150 FPS. Doesn't that seem low? Does anyone have any data on this length barrel?

2. Do you need Large Rifle Mag primers or just Large Rifle primers for this gun? I have seen both at various places. Loaddata.com says both in different listings and Starline brass says to use Large Rifle Mag (although they DON'T say that for the .500 S & W mag)

Can anyone help me out there?

Can't help you with the 460, but just wanted to welcome you to the forum Steve. Rules are simple, be nice and join in. The biggest handgun I shoot is the 44 magnum. Pehaps some of our guys shooting those big X frames can help you out.

Welcome to the forum, Steve! What is the intended purpose of he load you are developing? I used some of those Hornady 200 grainers in my Casull (I got 1,900 fps) and I have to say that they shouldn't be used on anything but thin-skinned game.

And even then, you will NOT need to grind any burger. Might not need a knife unless you need to cut some strands left hanging.
Here we go with more velocity and energy hunters instead of finding a boolit and load that works and is accurate.
The 200 gr bullet was designed for long range, flat trajectory and even at 200 yd's, meat loss can be great. Shoot a deer at 25 yd's and you might get a red mist blocking the sun!
On very large game they will fail.
Sorry Steve but you must do a lot of research here with posts. There are VERY experienced revolver hunters here with every kind of game shot. Do not make the mistake of using the wrong bullets and looking for nothing but velocity.
Granted, I have no experience with Barnes bullets so someone else needs to pipe up.

I shoot the 240gr. hornady xtp mag bullet, using 47 grains of 296. Accuracy is great with this load, clover leaf groups at 50 and 75 yards. Shots touching most of the time when I do my part. They opened up a bit at 100 yards. I shot a doe last year right at 100 yards with this load. Distance was ranged. Complete pass thru and not much meat damage. The exit wound wasn't much bigger than the entrance wound. This load was more accurate than the hornady 200 sst factory loads in my gun. I will most likely drop the load back to 45 grains after I shoot the rest of this box. The extra 47 grain loads weren't any more accurate than the 45 grain loads, and they hit at the same spot. 45 grains is the starting load for this bullet. Never have shot this load across the chronograph but figure it is accurate and did the job I wanted it to do so I won't mess with a good thing.
