Gemini Posted May 1, 2006 Report Share Posted May 1, 2006 OK went out this afternoon and had a sight-in with the .243 with the moderator fitted. First shot went 3 inches left and 1 inch low. (100 yds) Second shot was 4 inches left and 3 inches high. Wound over 12 clicks and shot the third round……which went 10 inches to the right. Don’t know what was going on but wound back across something like 20 clicks and was low and left again. Went home and had a look at the muzzle and was astonished to see bits of copper and ****e on the edge of the crown. So I got a magnifying glass out and had a good look and to my horror found that the crown was lop-sided, with a “Burr” on one side. I was going to take it back to the “gentleman” who threaded it, but thought about the petrol. So I spent an hour re-finishing the muzzle and then went to work with a marble and some 600 wet & dry, and re-crowned it. I have done this quite a few times in the past on rifles that I have had, and so it wasn’t in any way a daunting task, but it did make me bloody angry to think that the most important part of the job had been so crudely done. I will take it out again tomorrow (hopefully) and try again. I was very pleased with the noise reduction with the T8 though, and found it very good at keeping the scope on the strike. One thing that did come to light though was the heat haze that showed up through the scope after a couple of shots. Does anyone else find this or is it because my scope is set so low. The scope is set within 1 mm of the barrel, and as a result I do seem to get a very tiny bit of smudging at the bottom of the lens due to the moderator being so fat. It isn’t seen in the scope but does get picked up very slightly due to it being in the field of view, albeit out of focus. Has anyone else had this and would you advise fitting slightly higher mounts to lessen this effect. G.M. Quote Link to comment Share on other sites More sharing options...
Hodmedod.one Posted May 2, 2006 Report Share Posted May 2, 2006 Good luck with it Gemini. I hope that the marble trick has done the business. I think you ought to give the guy that threaded it a mention on here. He deserves some free advertising for making such a good job of your gun.

Dunkield Posted May 2, 2006 Report Share Posted May 2, 2006 You could try fitting one of those mod covers Gemini, a mate of mine made a blind out of of a nurses belt of all things to keep the haze down. Eventually he gave up with the mod for range days, just used to put it on to check zero once in a while. Raising the scope won't do anything as the haze is rising anyway, so you will still see it. I won't even comment on the threading job - you know who I use, and why... Quote Link to comment Share on other sites More sharing options...
deadeye ive Posted May 2, 2006 Report Share Posted May 2, 2006 Gm..............I see you went for the T8 in the end then On reading the start of this post I thought this sounds familiar ...........My groups(or immediate first few shots) were eratic when I first zero'd with the T8 and I put it down to over zealous maintenece of it or spraying silicon spray (NOT WD 40) as reccommended inside the baffles ....................I don't bother now ,nor do I bother much with the rifling and my set up is consistant albeit for a minor gliche which I know about . You can do nothing about the heat haze ...............I have a muffler on mine and it's still there so I would'nt bother raising the scope . I'm sure you'll have things sorted now Quote Link to comment Share on other sites More sharing options...
Gemini Posted May 2, 2006 Author Report Share Posted May 2, 2006 Cheers lads. As for the "Gunsmith"......well I won't comment on him yet as a friend still has two rifle lodged with him for threading and I would hate to put him in an embarrassing position when he goes to get them back. I won’t be using him again. For the price of his threading he was as good as a more expensive dealer who was closer to home, but it was the crowning that really bugged me. Anyway the muzzle and crown look a hell of a lot better now and should shoot a bloody sight better. G.M. Quote Link to comment Share on other sites More sharing options...
rogo Posted May 2, 2006 Report Share Posted May 2, 2006 What scope do you have?. I have been very lucky with my Rifles. A RFD friend who is a retired engineer has screwcut all my rifles @ £25 each and never have I lost accuracy. Touching wood! Mike. Quote Link to comment Share on other sites More sharing options...
The Bear Posted May 2, 2006 Report Share Posted May 2, 2006 Should have taken it back, given him a ####ing and had your money back, othewrwise he will think its an accepltable state to leave the crown in and carry on the same way in the future! Pay peanuts/get monkeys, its an old equation. Quote Link to comment Share on other sites More sharing options...
Dunkield Posted May 2, 2006 Report Share Posted May 2, 2006 slightly off topic Gemini, I stuck a white target patch on the turrets of my scope, with 'on' and 'off' written on them so I can quickly return to zero without wasting loads of ammo. My .223 with the PES on shoots low right about 9" over 100 yards! but Steve said it would do that as the barrel is very light.. Quote Link to comment Share on other sites More sharing options...
Browning Posted May 2, 2006 Report Share Posted May 2, 2006 Gemini, I got a similar haze off the T8 on my T3 .270, which has a low set scope (approx 2mm gap). I bought a neoprene sleeve for the T8 off eBay and that seemed to cure the haze problem. My T3 .243 never suffers the same haze from the T8, and I put that down to higher mounts, having approx 10mm gap. Quote Link to comment Share on other sites More sharing options...
