I've been shooting the 210 VLD's @ 3,200 ft/sec for awhile but I'm curious as to how flat (comparatively) the 168's would be over 800-900 yds. The load would be used for whitetails and/or antelope.

Realisticaly, how fast can the 168gr class bullets be fired from a 300 RUM? The printed sources seem to list very modest velocities for most bullet weights in the 300 RUM.

I'm currently using a 27" Broughton.

That's a good question and one I'm not likely to find out :) But I would think they would be A LOT flatter. If you're getting 3200 fps with your 210's, I would guess you could probably get 3550-3600 with the 168's.

Just for grins, I tried some RL17 (86 gr) with 180 E-Tips out of my 26" 300 RUM and I got about 3400 with that combo, which basically equalled H1000 and Retumbo. They shot well but I didn't like the low case volume so I went with Retumbo. I would think with the lower weight bullets, RL17 might outrun H1000 and Retumbo in the 300 RUM and you could probably get a few more grains in the case.

If you really wanted flat, the GS HV 177's would equal or exceed the 168 velocities with A LOT higher BC, .6+. One of these days I want to try the RL17/GS 177 combo. Should be interesting. It would way out run any of the big 338's except maybe the AM.

Just some things to think about...

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
