I have the x-bolt, but not a 280. A .300WSM in composite stalker. Great all around gun. There is almost no aftermarket support for them, but... it shoots pretty darn good out of the box. A custom rifle
challenger? Prolly not. But a ready to roll hunter, absolutely. I'm still working up loads. Was disappointed in my first few, but a "thrown together" 180 E-tip load started my season off rather optimistic so far... 3 in 1 ragged hole with 2 more pushing the group to nearly 1" at 100.
Very little aftermarket parts, if you plan to "upgrade" as you go.
NO aftermarket long action scope bases. There are some shorts though.
Sloppy action / overly loose bolt, if you ask me.
Not many people around here shooting them... so not a TON of info floating.
Trigger very nice, but only goes down to 3 lbs. (One aftermarket spring (Ernie the Gunsmith) is nice, but the trigger will break on a hard close on anything under 3... at least mine did) Of course... no aftermarket trigger options.
Any questions in particular.
