Tikka T3 Lite, not free floated

Hi, I've recently noticed that my Tikka T3 Lite cal. 270 WSM is not completely free floated, like my other Tikka, a 695 cal. 300 WM. As you can see, there is a pressure point, about 5 cm./ 2" ahead of the chamber. I suspect it to be responsible of the mediocre results that I get while shooting from the Harris bipod. Otherwise, when I shoot from the rest and I lean the stock just beneath the chamber, the T3 is VERY accurate. What is your opinion? Should I remove that pressure point? Thanks.

Wildboar, what I'm going to express is just an opinion. In the end, you'll need to try out any mods to see if they work.

My personal guess is that a pressure point as little as 2" from the chamber (from what part of the chamber, or possibly from the end of the front ring??) will have little effect on how the rifle shoots. Many barrels are bedded 1-2" in front of the chamber to avoid the action torqueing. Furhermore, many rifles with light barrels (in particular as the caliber increases and the barrel walls thin) shoot best with a pressure point - although that is most commonly positioned futher ahead than yours. A pressure point (unless it causes the barrel to return inconsistently with every shot), is not necessarily a problem until the barrel heats up. All you need is for the 1'st shot always to go to the same POI from a cold barrel.

My second guess, is that your less than satisfactory results with a bipod may well have something to do with (lack of) rigidity of your forearm. Injection molded stocks (like your's looks to be), have a nasty tendency to be wobbly in the forearm. You may get away with it when shooting with no particular pressure toward the tip of the forearm. But bipod shooting (assuming the bipod is attached to your front swivel) can be a bit of an eyeopener with respect to the effects of a forearm touching the barrel intermittently.

To check whether this might be the cause, check to see if you can compress the barrel/forearm sufficiently by hand for the barrel to touch the forearm. If yes, that *may* be an indication of trouble - in particular for bipod use.

To be more precise, that pressure point seems to give a sort of lateral support to the barrel, rather than an upward pressure.......

A good point....
