Guess my Velocity....

[Barrel Nut]

I'm pretty much changing everything and now my chrono is on the blink.

.260 rem
28" shilen
44.0 gr H4350
Rem brass
CCI BR2

I'll try to shoot it at distance in the next few days but for now your guess is as good as mine on velocity...Any Help?

A guess sure, 2870 FPS. With bullet a better guess, 3020 FPS.

Re: Guess my Velocity....

Rem 700 mag length of 2.800", AICS mag length of 2.860", AW mag lenth of 2.980"?

If SAAMI spec chamber, 2.860" OAL with 0.050" jump then I'd guess about 2850 to 2875 fps.
