Pillar Bedding Specifics?

Hello Everyone,

I have a Marlin XT-17 VR that I plan to put into a Boyd's tacticool stock. I'm making it into the ultimate bench rest .17 HMR. For ultimate accuracy, should I glass bed and pillar bed it?
(As of now, I'm putting it into one ragged hole at 25 yards, and nickel sized groups at 50 yrds, hoping to try it out at 100 yrds soon)

Also, are there gun specific pillars, or do you just select the correct threads for your rifle?

Also, anyone else's experience with the .17 HMR cartridge (tips) would be welcome.

Thanks,
F23
 
When I pillar-bed, the receiver is also bedded, especially for centerfires. Rifles with two receiver screws get free floated barrels. Those with only one either get another one installed, if possible; if not, a pressure pad or extended bedding in the forend, to lever the rear of the action firmly into the bedding.
 
^^rifle specific pillars can be purchased for many popular rifles, they're usually just about the right length and many times the tops are contoured to the shape of the action. Brownells (and other companies) will sell you pillars in pretty much whatever size and configuration you can think of (a file can always be used to shape the top of the pillar to the action). There are even universal pillar kits you can get that come with a variety of sizes.
 
No, never seen a 17 anything without a detachable magazine; same for lots of firearms.

Detachable magazines' accuracy issues for super accurate rifles were first noticed when the M14NM rifles were provided to and more precicely accurized by military rifle team shops in the early 1960's. They learned very fast that each magazine needed different sight settings for zeros at a given range. The fit each had to the receiver and rifle was not repeatable across them. Team members had to test several go get 3 that would shoot to point of aim with the same sight settings for rapid fire matches; two to shoot the 10-shot strings with a reload and a spare loaded with 8 rounds as a backup. These rifles would shoot 1/3 MOA at 100 yards, 1/2 at 300 and 2/3 MOA at 600 yards with good lots of commercial match ammo. It was easy to see 1/2 MOA differences in zeros with different magazines.

I've no idea what the difference would be with .17 HMR magazines. With a rifle and ammo that shoots no worse than 1/2 inch at 100 yards, it'll be easy to tell. They may shoot more accurate without a magazine installed.
 
Bart B. : I think those affects might be less pronounced on a bolt action firearm, but I will see if accuracy is affected with and without magazines.

Thanks for the clarification
