Thread: 308 Short Barrel Ammo Advice

My Bergara I think from memory was 2650(?) with the 18 inch factory barrel federal blue box . Is the 2850 the factory speed with a 22(?) inch barrel ?
So not going as fast , more drop.?

Federal claim 2820fps from a 24" barrel. I chrono'd it in a Remington 700 22" barrel at just on 2800fps so was happy enough with that.

Right quick update, I managed to get into town and pick up some ammo. I ended up grabbing some Hornady American Whitetail 165gr just to see how it went. RE-checked zero and shot a few groups to see how it would go. The rifle didn't think much of it with the best group being 3inches, with the fusion shot miles better interms of grouping. Thought bugger it I'll have a few shots at 300yards to see what it would do. Grouped poorly as to be expected based on the 100 yard grouping, and ended up with 24inchs average drop form my 100 POI once again going through the same system as last time its about 2200fps.

Now correct me if I'm wrong but I am shooting a heavier projectile that is already going 110fps slower than the fusion based on the factory testing would it not be inclined to have more drop than the fusion at 300m?

I am still waiting to get my hands a chronograph which will give me a more defiant answer but just though I'd see what everyones thought are on that. On a side note I have done this system to find my FPS/Drop for 2 other rifles with good success.

For anyone interested my scope is a Swarovski Z3 4-12x50bt with bases been correctly torqued.
