    moderator and harris bi pod

    Hi All
    This is my first post, i have been deer stalking for nearly 15 years and as my user name states, i am based in mid devon.
    I am considering getting a moderator for my Sako 75, any suggestions would be very welcome.
    Question,once the moderator is fitted, is it wise to leave it in place or remove it after each outing, or does this affect the zeroing?
    I have read some post's regarding the Harris Bi pod on synthetic stocks.
    I had a similar problem with my Sako, the stock came into contact with the barrel when fitted with the bipod,sending the odd shot off target.
    I overcame this by not over tightening the bi-pod onto the stock.
    Also don't hold the fore-end when shooting,this just adds to the problem.
    Never had a problem since.

    Hello and welcome devon deer stalker

    Once you put a moderator on, you will not want to go back, they make it a lot more pleasurable to use, lack of recoil and noise etc.

    I currently use a PES, on my tikka .243 but was originally on my old .270 about 3 years ago.
    I have a wildcat on my existing .270, but have still to try it out.

    The PES is one of the more common ones along with T8 and T12s as i say i have not got round to trying my wildcat out yet so can`t comment on them. No doubt you will have other input from this friendly site.
    I have always taken my mods off when not in use and have never had problems with my zero after putting them back on, but if you do leave it in place make sure you either take the bolt out during storage, which should be done anyway, or at the very least leave the bolt open, as after usage can create condensation and ultimately rust the barrel.

    Hope this helps

    Afternoon, Richard, and welcome to the forum.

    I use a Sako 75 .308 heavy barrel fitted with a T8 Reflex moderator and have no problems with either.

    Out of curiosity I took the moderator off after I zeroed the rifle and found no appreciable difference in the point of impact at 100 yards.

    Taking the moderator off after an outing then putting it back on has no effect either.

    It is the same story with the Harris bipod which I use also.

    Apparently the barrel harmonics of a free floating heavy barrel are less likely to change because of these.

    A mate using a Sako .308 with a hunting barrel has a different point of impact of at least 2" depending on if the moderator is fitted but the differnce is consistent. Taking the moderator on and off deos not change the zero in his case either.

    Hopefully this is of some help.

    A-TEC sound mod would suit you best, they are lighter than
    anything else, quiet as a T8 and wont rust.

    Weight wise they are just over 500g and 10" long but like the T8 sleeve over the barrel.

    Hello Richard and welcome.

    I use a T8 on three of my rifles, 222, 243 and 6.5x55, the same one for all three. No Sako's two CZ's and a BRNO, but I have not noticed any trouble with the accuracy, I always remove the moderator and give it a squirt of WD40.

    Hi I have a Harris Bipod on my Tikka synthetic stock with no problems
    and the moderator makes a hell of a difference.

    Harris bipod, and widcat mod. both great, no probs with taking off and putting back mod, although I've heard horror stories from others. I wonder how many of these are just in the mind of the shooter? Expect a problem, and life will surely throw one at you! All you can do is shoot it and see. My Sauer moved about 4" at 100yds when I fitted the mod. Re zeroed and thats that, job done.

    Hi Richard, I have a Sako 75 S/S which is fitted with a PES. I rarely remove the moderator but when I do it has never seemed to alter the zeroing. Although a little sceptical of moderators at first I am now a complete convert and it really makes the rifle a delight to use.

    I have a T8 on my Tikka T3, and it works well, it does however totally ruin the natural balance of the rifle, and I hate it because of that, however I always use it, as it really does shut the damn thing up.
    For fox shooting it's totally priceless.

    It will also save your ears from sound damage.
    Don't use as bipod, as the gun is heavy enough already, I use a piece of cut hazel, with a V at the top, I can always add another bit to make a tripod if I want and then leave it all in the hedge for when I am that way again.
