Ive got my eye on a Xp100 221 fireball. My questions are, how easy is it to swap out the barrel, could it being a 221 be swapped out for a common rd like the 243 and whats the going price on a XP100. Im looking at one and hes wanting $900 for it.

Back away, back slowly away. He is a thief, unless it has a $400 scope sitting atop it and/or some fantastic furniture. A 223 bolt face won't fit a 308 case head, but you can buy a different bolt.

He has a Burris 2x scope with some out dated furniture on it . Its not really uo my alley but I thought about playing with it and passing it on just to see the difference between that and the striker.

Way to much money for that price

This is what hes got , whats the going price?

Can't see the image - unless the Fireball is collector quality, you're looking around $450-500 for a base gun, then add for scopes, accessories, etc.

As Rod said, you'll have to either swap the bolt for a .473 bolt face for the calibers you mentioned, or have a 'smith open it up for you. The Fireballs are more plentiful, but a stock 7BR would allow you to make less modifications to go to the 308 family.

What SC said, about $500 + or -, maybe a little more because the scope is Burris.

I recently bought a minty 223 XP100, 14" barrel with thumbhole laminate stock and a pristine Burris 3-12x scope for $675 OTD. Deals are out there.

I thought it wa kinda pricey but wasnt for sure. I would still like to know the difference between the xp and the striker.

In a nutshell, caliber changes on the Striker can be performed MUCH easier than with a standard XP, which would require gunsmith work, etc. (However, I think Ernie had a switch-barrel XP built)

And L hand bolt on the Striker, as opposed to R hand design on the XP.

Anything else? I've handled Strikers, but never shot one. Up to 3 XP's now.

I have a couple of switch barrel XP's!
I do have a stainless steel Striker in 243 Win with a great trigger job (Mac's Gunworks). Was going to throw a 6-284 barrel on it, but may sell it.

The midgrip XP handles infinitely better than the Striker. The Striker handle is so fat the I couldn't even get to the trigger in a natural way, had to grind a bunch off of mine before I could shoot it. The Striker's left hand bolt handle is convenient, but it is a simple affair to turn an XP 45 degrees to allow your off hand to operate the bolt, or you can work it like you would a bolt rifle. The triggers are not even comparable. The Striker wins in ease of barrel changes, and the magazine is nice, but that is about it.

See your wrong Ernie! You know for some strange reason I have a thing for the 243!

Contact me if the vibe is strong!
