hill billy Posted October 26, 2009 Report Share Posted October 26, 2009 Hello iv got 2 T8 moderators one on my 25-06 and one on my 22-250, my thought came when the 25-06 moderator started to show a fracture in the bottom joining weld and i sent it back, i got a phone call from the chap at jackson rifles who asked what caliber of rifle it was on, i said .25 and he said well the one you have is bored to .30 cal so il send your new one in .25 cal which should be a tad quieter, it wasn't until tonight when cleaning the 22-250 that i noticed the moderator on that is also bored to .30 cal my question is do you think this makes a dfference in noise levels ? before you say well swap them over and find out the 25-06 is factory screw cut from finland and they cut it to 14x1 not our usual of 1/2 unf Quote Link to comment Share on other sites More sharing options...
Billy. Posted October 26, 2009 Report Share Posted October 26, 2009 (edited) Yes it will make a difference. I'm not saying it'll be noticeable, but there will be a difference. Oh and you might even notice there is slightly less recoil as well. Edited October 26, 2009 by harfordwmj Quote Link to comment Share on other sites More sharing options...
hill billy Posted October 26, 2009 Author Report Share Posted October 26, 2009 To give credit were credit is due the T8 has made the rifle vertually recoil free ( the 22-250 ) but i suppose that is helped by the heavy barrel, this sound stupid i no but since changing moderators to the T8 i have never missed so many foxes before i don't no if its me ( more that likely ) but i have lost all confidence with it.

Billy. Posted October 26, 2009 Report Share Posted October 26, 2009 Garyb had a nightmare when he stuck his T8 on his rifle, as it started throwing bullets off. Not in a sense of just the POI, but the actual bullet hitting the paper side on...! Try changing the bullet grain and go and fire a few rounds at 100 yards on a still day. I personally am not a big fan of the T8, they are prone to rust and don't live as long as the others on the market. Quote Link to comment Share on other sites More sharing options...
lazza Posted October 27, 2009 Report Share Posted October 27, 2009 Hill billy, I also have 2 T8s one on a 22-250 and .30cal which is used on my .243 and will be used on my30-06 when I get it cut and threaded. I've had the 22-250 mod for a while now and had some teething problems with it , however it shoots really well now and I'm now used to the balance on the heavy barrelled 22-250. What odes it shoot like on paper? Quote Link to comment Share on other sites More sharing options...
garyb Posted October 27, 2009 Report Share Posted October 27, 2009 (edited) Garyb had a nightmare when he stuck his T8 on his rifle, as it started throwing bullets off. Indeed I did.. See - http://forums.pigeonwatch.co.uk/forums/ind...c=67800&hl= TBH I very much doubt, my issue was just because of the T8 - I'm sure it would happen with any brand of moderator on the end of that rifle. How does it group on paper - say 5 shot group @ 100yards Hill Billy? I fixed mine by changing up to 55grn heads - very few foxes escape alive these days!

garyb Posted October 27, 2009 Report Share Posted October 27, 2009 since changing moderators to the T8 i have never missed so many foxes before i don't no if its me ( more that likely ) but i have lost all confidence with it. I take it you have checked the zero with the mod on....? It's a myth that you can shoot a rifle with the mod on, then take it off - for the POI to stay the same. With Mine (and others) the difference in POI between mod on & off - is about 5 inches - easily a missed fox. Quote Link to comment Share on other sites More sharing options...
Mr_Logic Posted October 27, 2009 Report Share Posted October 27, 2009 Yep I've got about the same degree of POI shift with my .243. Certainly for the Predator, rather than T8, the size of hole makes a massive difference - 30 cal on a .22 CF is loud, put the right baffles in it and all of a sudden it's nice and quiet Quote Link to comment Share on other sites More sharing options...
hill billy Posted October 27, 2009 Author Report Share Posted October 27, 2009 I brought my 22-250 second hand from a chap that worked at rifle craft and he had spent a lot of time and money perfecting the rifle , it's heavy but once on the bipod it's perfect and the only thing making a diffrence in the groups is probably me as iv bench fired it at 100 yrds and clovered 5 bullets on a fairly still day, i use really lively ammo which i think may contribute to part of the problem, a local gun shop to me closed down and i brought 260 of these bullets at only £10 a box which im just coming to the end of now i think iv got about 15 left there federal 40 grain ballistic tip i think they leave the muzzle doing some 4100 feet per second, with my old moderator i would shoot 50 foxes a year and only miss about 8 or 9 if that really, now since i have put the T8 on iv missed about 5 out of the 1st 15 i shot at which really annoyed me so im affraid a few of the next ones got shot with the 25-06 as the 22-250 was grounded from coming out lamping for a while lol Quote Link to comment Share on other sites More sharing options...
Billy. Posted October 28, 2009 Report Share Posted October 28, 2009 Your barrel might be wearing out... Go and have a proper check by shooting off a decent rest at about 50 yards. If you don't get at least a 1/2" group at that distance, something might be up. When you zero it, do you allow the barrel to cool between shots?

hill billy Posted October 28, 2009 Author Report Share Posted October 28, 2009 the barrel isn't overly old to be honest it would supprise me if it was that, if i put it on the bipod i can get pretty dam good groups but i can't understand why i have missed so many foxes since fitting it Quote Link to comment Share on other sites More sharing options...
lazza Posted November 1, 2009 Report Share Posted November 1, 2009 Try having a go on paper without the bipod to see whether its holding zero. Quote Link to comment Share on other sites More sharing options...
humperdingle Posted November 1, 2009 Report Share Posted November 1, 2009 I take it you have checked the zero with the mod on....? It's a myth that you can shoot a rifle with the mod on, then take it off - for the POI to stay the same. With Mine (and others) the difference in POI between mod on & off - is about 5 inches - easily a missed fox. I found the same. Not with a T8, but with a Predator 8 on my .22-250. The POI was a good 4" down and left after the mod went on. Took it off, and the POI was back to bang on zero. I'd been told by a gunsmith that it shouldn't change the POI, but in practice, it clearly does! As for differences in sound level, my mate and I both have .22-250 cal rifles. He has a P8 compact with a larger baffle bore (.308 I think), I use a P8 standard length with .22 bore, and I cannot detect a difference in the noise. There quite probably IS a difference, but my ears are unaware of it. Quote Link to comment Share on other sites More sharing options...
garyb Posted November 1, 2009 Report Share Posted November 1, 2009 (edited) Stealth Stalker and I know a chap, who we believed was a seasoned stalker... he was explaning to us how he had missed a Muntjac buck on his last stalk and assumed that the rifle had taken a knock. It was only after speaking to him further, when he mentioned that, he had removed the moderator from his rifle on the advice of a friend, in order to reduce the weight for woodland stalking... Anyway, we watched him punch paper to "check" the zero.. The verdict... again, a good 5-6inch difference in POI between mod off and on. A lesson learned.
