walt1980 Posted August 28, 2013 Report Share Posted August 28, 2013 Been given a mod which is marked as being for a 22-250 but wondered if it could be used on my .243? Pulled it apart and measured all relevant holes and theres clearance through for the bullet head? Any other reasons? T Thought I'd ask the cleverer people of here!

walshie Posted August 28, 2013 Report Share Posted August 28, 2013 I wouldn't as the 22.250 mod is for a .224" bullet and the 243 uses a 6mm bullet. What did you measure it with? Quote Link to comment Share on other sites More sharing options...
walt1980 Posted August 28, 2013 Author Report Share Posted August 28, 2013 Measured all holes with a vernier! Quote Link to comment Share on other sites More sharing options...
walshie Posted August 28, 2013 Report Share Posted August 28, 2013 Dunno then mate. It's marked up for a reason. Personally I wouldn't risk it, but then I'm an old fusspot. Quote Link to comment Share on other sites More sharing options...
Paddy Galore! Posted August 28, 2013 Report Share Posted August 28, 2013 marked for 22/250? have you got a piccy you could post up? what make is it? never seen or heard of that specificity, usually they're stamped or proofed- .22 cal, .25 cal, .30 cal etc Quote Link to comment Share on other sites More sharing options...

Really wanted to try it! :-( keep it man! just get a cheapy T8 for the .243 for now, or get the hardy bored out to cope with the extra 0.44 mm Quote Link to comment Share on other sites More sharing options...
walt1980 Posted August 28, 2013 Author Report Share Posted August 28, 2013 Haha got a predator 8 on at the min, but yeah a drill might be coming out lol with a vice and a long bit of string to do the test fire!!!! Quote Link to comment Share on other sites More sharing options...
moor man Posted August 28, 2013 Report Share Posted August 28, 2013 (edited) Yeah prob will swap it, but its soo nice n shiney! Gotta say bl..dy light! Really wanted to try it! :-( Keep it! Put in for a .22-250.......sorted If its specd for .22-250 wont it need proofing after any work to stay on the right side of the law? On the other hand .44mm isnt a lot is it? How much 'meat' is there to play with, so to speak? Edited August 28, 2013 by moor man Quote Link to comment Share on other sites More sharing options...
walt1980 Posted August 28, 2013 Author Report Share Posted August 28, 2013 Plenty of meat. As far as I can see its only the exit hole that's even close!! Such a tiny amount, almost worth a try, it's not like the bullet head is flush with the edges when it's fired?! Wondered about pressures etc tho? Not sure on how much punch is behind a 22-250? Bigger bang n pressures or not?? Quote Link to comment Share on other sites More sharing options...
Alanl50 Posted August 28, 2013 Report Share Posted August 28, 2013 Give "Rifle Craft" a ring they are the importers, sellers and suppliers to the trade. The mods come from New Zealand. Alan Quote Link to comment Share on other sites More sharing options...
fieldwanderer Posted August 28, 2013 Report Share Posted August 28, 2013 Afaik, powder and pressures are quite similar between the two. I'm not sure about the legal side but I'd personally be prepared to bend that particular rule. My concern would be a bullet strike, I had one on a .22lr that destroyed the mod (sako), its not pretty but at least it's away from you. Destroy £250 mod and risk an injury? I'd have a good think about that one to be honest. I'd bet good money the importer won't recommend it; they wouldn't risk it even if they knew it would be ok. Too much "where there's blame, there's a claim". Quote Link to comment Share on other sites More sharing options...
geordieh Posted August 29, 2013 Report Share Posted August 29, 2013 How big are the holes Geordie Quote Link to comment Share on other sites More sharing options...
cal 7888 Posted August 29, 2013 Report Share Posted August 29, 2013 Hardy's only come in 6.5mm bore and .30 cal bore. it will be marked as a 22-250 as thats what it was proofed on! it will be "engraved" as a 22-250 but thats the proof mark. you can either cover it up and just leave it and say it's un proofed or have it re proofed as a .243. your coice. you CAN use this on the .243 no problem atall! im just abit curious how you got it appart to measure it... as they are a pressure sealed unit! haha ATB callum @ Riflecraft Quote Link to comment Share on other sites More sharing options...
al4x Posted August 29, 2013 Report Share Posted August 29, 2013 im just abit curious how you got it apart to measure it... as they are a pressure sealed unit! haha at that point it might be worth making absolutely sure it is the mod you think it is Quote Link to comment Share on other sites More sharing options...
walt1980 Posted August 29, 2013 Author Report Share Posted August 29, 2013 It's now going to be a paper weight!!! Lol Quote Link to comment Share on other sites More sharing options...
rtaylor Posted August 29, 2013 Report Share Posted August 29, 2013 I might be wrong on this one but if you took a .243 round and put it in the exit hole of the mod, so long as it doesn't touch the sides, doesn't that make the hole big enough? If you like I can measure the internal and exit holes on my wildcat and see what the difference is? If the bullet isn't going to clip I can't see it being a problem.

njc110381 Posted August 29, 2013 Report Share Posted August 29, 2013 The mod needs to have more play than just a bullet fitting through the hole in the baffle. What size are the holes? Quote Link to comment Share on other sites More sharing options...
Alpha Mule Posted August 29, 2013 Report Share Posted August 29, 2013 Just my uneducated 2p, but other than actually clipping the hole sides and enlarging them in a dramatic fashion, isn't the pressure difference more of an issue. I reckon you could do an exaggerated safety trial to see what happens - on the understanding that you may peel it apart / get a nice light mod that works perfectly well.

cal 7888 Posted August 30, 2013 Report Share Posted August 30, 2013 if it is a hardy and has 22-250 on it, it WILL fit and be FINE on a .243! Quote Link to comment Share on other sites More sharing options...
