Freedom Arms sold 260 grain bullets designed for their revolvers. Mike, I believe you are thinking about the 240 XTPs. To the best of my knowledge, 260 grain XTPs in .45 caliber do not exist.

And yes, the jackets are heavier on the 260 grain FA bullets.

Exactly...........The 260's that were moving in excess of 1700FPS were FA bullets..........

I agree; 200 fps isn't going to make a tremendous difference. The main use of a chronograph is for working up loads to prevent overcharging of a powder.

I usually use the chrony to check the Std Dev between shots to make sure the powder/bullet combo is stable. It is hard to judge pressure by velocity, but you do know that if your velocity is over the published amount, you are definately in trouble. I will agree the XTPs are not designed for the 45kPSI or greater handguns. The best source of info would be Hornady themselves, when in doubt, call customer service. The other beauty of the 454 is downloading it 20% will knock the crap out of anything in North America under 100 yards.

True enough, but I've had loads with dismal statistical numbers shoot well out to the ram line.

I believe that I got confused with the nosler 260 gr bullets. ( a senior moment)

That point was made ealer in the thread......

Didn't see it my mistake!

Not a problem and looking back,I think that it was a good idea that you brought out that point again..........
