View Full Version : Question about barrel block set ups

12-16-2015, 02:08 PM
If you were going to have a new rail built what barrel block set up would you go with? Pro's and con's ? TIA

Best I ever had was a round hole with the barrel bedded but I think that was because I had a really good barrel at the time. Pretty sure that if everybody chimed in here you would learn that one is no better than the other.

That said, if I had to choose, I think the rail that has the action bedded and the barrel free is the better way to go. Not from a shooting standpoint but it's easier to swap barrels. I don't actually have experience there but it seems so....and I've been beaten over and over by those darn things.

Too bad theres no polar actions made anymore

Round hole Delrin sleeve! Lots of guys shooting them! Dusty, I have an un modified Polar, of course its on my Hasecuster rail!

I prefer a round hole..... nicely finished....close to the barrel diameter... ( +.001-+.002 )...and the use of rosin.

My rail has the delrin sleeve but most have the v block. If you have a complete pkg that shoots good- barrel, action, trigger, rail, scope then i dont think it matters how its mounted as ive seen em all win.
Steelhead, tell me about that polar. What port config etc. i have a big soft spot for polars. Most got cooling slots milled in em back in the day. Ive had some sweet ones back in my cruiser shooting days.

It is a dual port and has all the vent holes you speak of, and last year I sent it back to Kelblys and had them add their ejection system and new FPspring and basic bolt cleanup. Oh and it is has a 308 bolt face but is used only as a ppc! During the off season I am going to set the barrel back, or buy a new one and chamber it. Since I do my own barrel work, I can set it back and only have my time invested!

Why do most Polar actions have "vents" cut in them?

Back when people were using polars alot i had one i really liked and it was unmolested. I asked skip otto why most had vents and did i need to vent mine. He said one guy with a new mill way back vented it and said it had to be better instead of the heat having to go up the action and out. I thought it sounded fine and skip told me to keep mine original since it may be one of the last originals. So i decided to flute the barrel under the shroud. Never seen a difference either way. Now i have a sleeved 40x with the polar footprint and a shilen action thats bigger than that.

The last polar cruiser i sold was to a member here. I sure miss that one and wish i had another to add to my collection

I could build a cruiser with this Polar, it has the square back tang, and I do have a brand new Lee Six stock, but it is for the tapered tang! I don't have a mill but I do have a buddy that will let me use his to recon tour the tang, and doing that would not have an impact on still using it as a rail gun. I have considered buying a new rail gun and turning the Polar into a Bag gun, only because I have never shot a bag gun! Sure seems like most of us that shoot are tinkering with different options all the time!

Man just whiddle that stock out instead of the action. I love cruisers especially when they have a railgun type base. I have a few and still toy with em but as often as a railgun match comes along ill be shooting a rail. I do get sick of toting it around tho
