spandit Posted July 3, 2014 Report Share Posted July 3, 2014 After my reloading/shooting session the other day, I removed the mod, collected the spent cases and inspected them for flattened primers etc. I then strolled down to the target to photograph it. It must have been at least 5 minutes before I casually unscrewed part of the mod to find out if was still full of smoke/vapour. Glad I store it off the rifle Quote Link to comment Share on other sites More sharing options...
Dougy Posted July 3, 2014 Report Share Posted July 3, 2014 You should see the rust on the crown on some of the one's ive seen, its not a good idea at all to leave them on. Quote Link to comment Share on other sites More sharing options...
jgguinness Posted July 4, 2014 Report Share Posted July 4, 2014 (edited) I bought a 223 where the lad had stored it with the mod on. In fairness I was new, first centrefire rifle and didn't look properly. Grouping was all over the place. Had it bore scoped and the crown plus say 2" was toast, knackered completely. New Bergara barrel fitted, at my cost obviously by my local smith and she was grouping 1/4" at 100 yards. A lesson learned, steep learning curve and cost me in the pocket, but I now know!!

Dekers Posted July 4, 2014 Report Share Posted July 4, 2014 Leave it on and expect issues, rimfire or centrefire! So, take it off an clean it, (and the gun/crown) then put it back on, my rifles are all stored with mods attached, never a hint of a problem!

spandit Posted July 4, 2014 Author Report Share Posted July 4, 2014 My .22LR hits the door frame when slung on my back with the mod on so I generally leave it in the ammo safe Quote Link to comment Share on other sites More sharing options...

steve_b_wales Posted July 11, 2014 Report Share Posted July 11, 2014 I use Copper Slip grease on all the barrel threads of my rifles. I also use it on my shotgun chokes. Quote Link to comment Share on other sites More sharing options...
arjimlad Posted July 11, 2014 Report Share Posted July 11, 2014 Doesn't taking the mod on & off alter your POI ? I take mine off for a clean every now & then & check the zero after. Store the rifle barrel down. Quote Link to comment Share on other sites More sharing options...
Les*1066 Posted July 11, 2014 Report Share Posted July 11, 2014 I use Copper Slip grease on all the barrel threads of my rifles. I also use it on my shotgun chokes. Ditto. A little dab of Copper grease on the threads will stop any binding/galling/corrosion etc. It always pays to remove the moderator ocassionally, just to make sure that everything is OK though.

dadioles Posted July 11, 2014 Report Share Posted July 11, 2014 Doesn't taking the mod on & off alter your POI ? It shouldn't. I can see how, in some circumstances, it may affect barrel harmonics but I have never had a problem. Take the mod off, put it back on again, no change in poi.

Dougy Posted July 11, 2014 Report Share Posted July 11, 2014 Doesn't taking the mod on & off alter your POI ? I can honestly say no, not in my case. Of the 4 that I use regular over 100yds and 1 of those at up to 400 not noticed poi change. Quote Link to comment Share on other sites More sharing options...
Berettacocker Posted July 11, 2014 Report Share Posted July 11, 2014 I've been told by a few people that if you leave mod on, it will can cause condensation, that will rust / knacker your barrel . Don't know if true, but why take the chance? Also vigorously spray inside of my T8 mod with WD40 after use ( think T8 mods are prone to corrosion ) never loses zero but first shot is a bit smokey/ smelly!

spandit Posted July 11, 2014 Author Report Share Posted July 11, 2014 Mine is a T8 mod. Was pretty dirty inside, although a lot of that could have been from the WD40 I've sprayed in if Quote Link to comment Share on other sites More sharing options...
kent Posted July 11, 2014 Report Share Posted July 11, 2014 Doesn't taking the mod on & off alter your POI ? I take mine off for a clean every now & then & check the zero after. Store the rifle barrel down. Not unless you have an issue with all being true it wont leave it on and it will be on for good !! .... take it of every time i use silicone on the threads keep it clean and you will be trouble free I should use silicone grease for that its not good for the metals. Use copperslip or any lithium type grease Quote Link to comment Share on other sites More sharing options...
Alycidon Posted July 11, 2014 Report Share Posted July 11, 2014 You should see the rust on the crown on some of the one's ive seen, its not a good idea at all to leave them on. Always take mine off but the T8 is rusting. A Quote Link to comment Share on other sites More sharing options...

Underdog Posted July 12, 2014 Report Share Posted July 12, 2014 The other night I shot just five rounds from my 22, when home I took the mod off and the crown was dripping wet! Hooray for lubed bullets but I have been trying to warn jacketed bullet users of potential damage for years! Quote Link to comment Share on other sites More sharing options...

camokid Posted July 27, 2014 Report Share Posted July 27, 2014 my guns look as new as the day i brought them and never once had issues using silicone grease on the crown.. i clean and put a fresh wipe after use Quote Link to comment Share on other sites More sharing options...
spandit Posted July 27, 2014 Author Report Share Posted July 27, 2014 Silicon is the last thing you want Do you mean silicone sealant? I'd agree in that case but normal silicone oil should be fine - the kind they use to stop belts squealing. Quote Link to comment Share on other sites More sharing options...
