Hello everyone I'm new here and would like to say hi

i have a model 10flp .308 with a 24" barrel with 1.10 twist (first gun i ever bought new)
i love the long distance tactical/sniper side of shooting so this gun fits me well.

i basically want to get a new barrel because (I think it makes the gun look meaner) i know
there are other performace benefits as well. i really like the way the 26" barrels look on these guns
i have been looking a McGowan's website for prices.

so now i saw the 28" barrel and want to know (if there is any) benefit going from a 26 to a 28 inch barrel in .308
i plan to shoot light to med ammo 110-175 grain (long range)

I'm not a gun expert but i think there comes a point when you can over barrel a rifle.
what are the benefits i can expect to see from changing from a 24" barrel??

my friend has the newer 20" barrel model and he wants my 24" inch
