Hi everyone

I want to pick up a semi-auto .308 rifle, I am hoping to get the Troy 102.

However a few questions I have are holding me off. Namely:

1. Most bulk affordable .308 ammo is 145-150gr but the Troy and other semi auto rifles all seem to be in 1:10 twist rates which from what I can find online favours 168gr upward ammunition I don't want a high $ per shot rifle or to have to reload. Will the rifle be able to hand 145-150gr ammo effectively?

2. Most rifles in .308 seem to use 1:10 twists, if 145gr ammo is not suitable for these rifles then what are they good for?
 
Bulk affordable ammo was never designed with accuracy in mind. If you want to get the most out of your gun you are going to have to buy premium ammo

Agreed, but given it is the ammo that many people are most likely to use most of the time I would have thought that rifles could/would be designed around that affect.
 
to really realise the full potential of the 308 , you got to RELOAD- and most of the guys on this board favor at least 150 grain,and if you look at your greenhills forumulas you'll see that there's a good portion of the rifles designed around a 1/12 twist- your 1/10 can accommodate all the way to 200 if need be , but most folks stick with 150, 165,168 and 180s for really heavy game- I've a got a 305 in 1/12 twist that I've had for many years and it has yet to fail me- just remember when you're reloading it's 4 including the first one and gone-ie 3 loads and trash it

you also have to ck with your range as some ammo is STEEL CORE and will PUNCH RIGHT THROUGH THE BACKSTOPS- Trust me, it's a lot more complicated than just buying the rifle, ammo, loading it up and going shooting- if you're going to be responsible

Then look somewhere else... A semi-automatic 308 is not for you.
The cheapest ammo you'll find is about $1 per round, almost always FMJ.
And you can't shoot any FMJ's at indoor ranges either, if that matters.
Either 223 or 9mm, if you're on the cheap... WK180 or FX-9

Your thought process here is baseless. A 168 grain bullet may benefit from a 1:10 twist, but that does not necessarily mean a 1:10 twist is somehow detrimental to a lighter bullet. Shoot all the 145gr bullets you want out of a 1:10, none of the bullet or the target or yourself will ever know the difference.
