You probably need a faster twist barrel if you are going to shoot heavier than the 124 grain hammer hunter in a 6.5. Check hammer's website for each bullet to ensure your barrel will stabilize the bullet.
Kuiu Attack Pant in Verde size 30. Have been used a few times so there are some small pulls and scuffs in the lower legs and knees. No holes or anything that impacts the functional usage of these pants. Asking $80 shipped.
I believe the most important thing with shotguns is feel and how they swing for you. I'd try to pick-up both to compare the options. If a 26" feels better, go for it. 28" barrels tend to just swing better for me personally.
