take a guess!!

The 30-06 load is actually pretty close to mine. I use IMR 4350 which is about the same and my barrels are 26 inch and velocities run around 29,850 FPS. I'm gonna say yours will run 29,800.
 
The .30-06 I'm guessing 2965 fps
The .270 I'm guessing 3125 fps

Good luck.
(And take a video so if you do shoot your brand new, highly anticipated chrono, we can all watch it over and over and over ect...:D:D)

Finally got to the range. And chronoed both guns.

The 30-06 was shooting Average of ten rounds at. 2813. The shots in order are. 2807 2817 2817 2817 and 2806. That is a high to low difference of only 11 feet per second. Not sure how to calculate SD.

The 270 wsm five shots in order were. 2940 2952 2966 2949 and 2977. High to low difference of 37 feet per second still would like to know the standard deviation. By the way that was with a 150 grain ballistic tips seated to the lands with 67 grains of magpro.

I will look through the whole thread and I will pm the winner of the bullets I promised.
 
I win on the .30-06:D I was only off by 1fps. I don't want the bullets though.

I believe OneOldSap would be the overall winner, if I'm not mistaken.

He's off by 13 on the 30-06 and 31 on the 270.

You win a box of sierra match king bullets 308 caliber in the 200 grain persuasion. If you want them that is.

And yes that load for the 30-06 groups very well. 3 shot groups hover around half an inch. That is with sierra game kings.
 
too late for me to guess, but I wasn't going to anyway.:D

What I was going to say is that my experience with chronos and several guns and loads is that the data in the loading manuals is pretty close, and individual guns will show individual differences. I have see as much as 100fps above, and below the published data from different guns, although usually it is much less. Rarely it is spot on, but that, I think is just serendipity.
 
Kilotanker.. your original post said 165 grain SST's.. I call miss trial..... You wanted us to pick the velocity for SST's and you tell us now that velocity was with Sierra Gamekings!!???
Debothcery abounds!!!:eek:
 
Hooligan. I also chronod a few SST bullets out of them and the difference was negligable . The standard deviation was bigger for the SST.
