300 RUM, 180gr TTSX, 95 grains Retumbo; Velocity?

I haven't purchases a chronograph yet and was curious on what my muzzle velocity will be with this load since none of my reloading books have anything similar to this:

300 RUM
26" barrel
180gr Barnes TTSX
95 grains Retumbo
Fed 215 primers
COAL: 3.625

Load has no pressure signs and accuracy is .5 MOA. I am thinking it should be around 3300 fps, but am curious if anyone has used a similar load that has velocity documented. Thanks.

You may be over 3300.

I have a load for a 180 TSX in my RUM. I am running a 27" Lilja barrel. The load is: Nosler Custom Brass, Fed 215GM Mag Primers, 94gr Retumbo, COAL 3.635~ .070" off of rifling. This produced 3385 fps and showed great accuracy potential with a .562" pair at 300 yards (this is not my main load, would need to prove accuracy). ES was 17fps. Hope this helps.
