Of all the rifles I own, my 25 wssm prints the smallest 100 and 200 yard groups.
Time after time. Browning A Bolt, factory barrel. Six pound rifle.
Dead? Maybe not... on the fringe of popular? More like it. And new brass is just a little hard to find. And perhaps all this makes me 1/4 bore kind of crazy.
Tell me something, if you're the kind of guy who appreciates the 6.5 caliber
why would you want to mess around with 1/4 bore bullets? All the best BC bullets are 6.5mm. Right?
If you want to hunt, up to deer size game, either one will work.
And the 6.5 will work farther out there.
Have you considered the 6.5 Swedish? Like the 25 wssm there is little recoil.
Unlike the 25, brass is cheap and available. Might work well for you.
