To 6.5 or not to 6.5 that is the question!

One man’s opinion… 6.5’s don’t kill that well. 25-06 and 270’s kill very well , is that because of the lower sectional density? Who knows.

My next build would be a 1in7 twist 6mm creedmoor
25-06 shoots 6,53mm bullets

Which 6.5 are you comparing it to? I suspect that it will be one with less powder volume than a 30-06 variant.

Also assuming equal bullet weight the 6.5 sits between the 25-06 and .270 sectional density wise.

In my experience the 6.5s kill well and better than 6 mms for a similar sized cartridge.
 
Thanks for the unrelated info , we are talking about 6.5mm ( .264 ) cartridges
Stick a 140 gr .264 into a necked down 30-06 case, load it to its capabilities and it will flatten deer just as well as a 120 gr from a 25-06 if not better.

What you are seeing is the result of of burning 15-25% more powder behind a similar weight bullet, not the <15 thou difference in bullet diameter.

Like 6,5*64 Brenneke or the most common wildcat in Sweden 6,5-06. For now the .257 bore cartridges are limited by slow twistrate some manufactorer are probably going to release a cartridge for a faster twistrate so the high BC bullets can be developed. .270/6,8mm might be the new thing now then US army has adopted a .270-08 style cartridge.
 
Did you try Sako Powerhead II 120gr (copper) in your 6.5x55?

I find it extremely effective.
I did. Worked ‘ok’, shots under 40yds gave way to some runners of quite exceptional distances, esp 25-30yds shots.

Saw a few reds travel 75-125yds when shot at around 200-250 yds.

The oryx 156g just drops them all - having a rethink about transitioning now until I must - despite having shot copper for around 2-3 years now.

Still running the blade in the .308, but might go back to a 150g partition

Under 40 yds and you’re getting runners? Where are you shooting them?
