A few years back I bought a Remington 700 SPS Varmint (26" 1 in 12 twist heavy barrel) in 308 Win. They had them on sale for $420 or $440 IIRC, so I had to buy it.

I swapped out the cheap flimsy plastic stock with a Bell & Carlson M40 stock, bedded the action and put a Timney trigger in it. It has a Leupold Mk 4 4.5-14x50mm LR/T scope. It shoots Federal Gold Metal 168gr. BTHP absolutely awesome, sub MOA.

I wanted to try the Federal Gold Metal 175gr. BTHP to see how well they shoot. I was wondering if the 1 in 12 twist would work with the heavier bullets? Doesn't the USMC M40A1/A3/A5 all have 1 in 12 twist and use 175gr. bullets?

Thanks, NYH1.
