I'm curious as to what actual velocities are being recorded compared to what's on the box.
I've tried the 7mm08 (150 ELDX) and recorded 2520fps with a 20" barrel. Box lists 2770 fps (I'm assuming a 24" barrel)
I have already come to the realisation my barrel is a little slower than average but I still would have expected closer to 2600.
2670 from 20”tikka
Shot over a magneto speed and validated to 600m.
Shot real good but killed slow. What chrono you using? Can you validate at long range?
20inch Kimber Montana. 2636 fps shot over a magneto speed.
Attachment 243265
Dam that SD reminds me why I handload
Just a cheap Pro Chrony however I have used this alongside a lab radar and they consistently showed 20fps difference ( I can't remember which way but it was the same every time)
Haven't validated it at distance.
Yes, to be fair that actually sent me on my reloading journey. My 308 kimber shooting hornady whitetail 150gr had a SD of 6.2 fps, which I thought was much more respectable.Quote:

308 tikka 20” barrel suppressed. 178 grain precision hunter goes 2540 fps. Says 2600 on the box
Some is way better than most can handload I've had hornady doing 5Quote:

I use it in my Tikka Aspire in 7mm08, 24" barrel dpt suppressor: 2671fps
iv found 6.5 prc to be a bit slow.
that's slow.how many rounds through the barrel?Quote:

Box say 2770 for 24"barrel. so for a 20" barrel 2570-2670 would be the expected velocity.
Then some are faster than others, worn throat etc, over my head.

2690 fps from my mates 20" kimber
That measurement was taken from the first 3-5 rounds the barrel had through it. Not sure if that makes a difference?Quote:
