6.5mm Projectile for Moose

[Bluumoon]

Those are estimated velocities at impact location based on muzzle velocity and range.

I can’t reach pressure with 130gr TMK and N565 before I run out of case volume but I can see mid 2800s MV with N565 with the TMK.

I think if I pursue that bullet long term I’ll try n560.

Also I’m at sea level. I can’t get 2600 with 43gr h4350 and 6.5cm without flattening primers.

Checking out the new garmin yesterday, I’m at 2656fps w 130gr TMK 41.5 gr h4350, lapua srp brass, 18” Tikka 6.5Cm.

Does altitude have an effect on velocity at the muzzle, didn’t think that was a thing?

We harvest moose every year with 150g eldx from 7mm08, moose are not as tough as people think and they tend to not run very far. Put any non bonded bullet in there and they will die fast. We have over 20moose killed in my family with everything from 375-7mm and the 150g eldx is hands down the most effective if shot in the right place.

It shouldn't affect muzzle velocity, only drop at distance.

Good question...taking a step back... I just thought it did. I got 28XX on a full case of N565 in a PRC case behind a 130gr TMK with no pressure. So it seems like at 165 yards or so launching with a PRC is like shooting that deer 1 foot away with a 6.5 Creedmoor.

Whenever I feel like jumping on one of those caliber comparison threads I get hung up on barrel length, powder, bullet, loads etc and realize as Form says most people are just typing out feelings myself included sometimes.

PS: I can't touch 2650fps with 43gr H4350 behind a 147gr ELD. If there are no physical barriers with altitude then maybe one or both of our chronographs are off?

130 TMK, I think I was at 2695 with 43.5gr.
