[QUOTE="VinceMule, post: 2757308, member: 122164"] A couple of things on the 22/243 AI that plague a lot of shooters. First is the web dia on the reamer vs the Brand of brass that you choose. Most figure that they will run the tough Lapua brass, but Lapua is MUCH larger in the web than Winchester. If you want to use Lapua brass, then order a reamer off of EUROPEAN CIP specs not SAAMI specs of American. This issue of CIP vs SAAMI is no laughing matter, in fact, it is a deal killer if the gunsmith's reamer is not set up correctly. Many guys get busted on this issue of CIP Lapua brass, and I personally know 4 guys that wasted money on Lapua brass due this reason. Second, when you neck down to 22 calibers, you should count on a clean-up neck turn on your brass. This is another issue with the brand of brass you choose. Web dimensions on the reamer for Lapua brass are best in the .4732 area while Winchester will be .471. You rarely ever hear of anyone running a 22/6 Rem AI. 80g A max at 3650 and never use a full-length sizer is real world, with 3800 bring top end, Retumbo and fed 215's. The 80g A max at 3650 is a great Deer and Antelope round. The difference between the 22/243 AI and the 22/6 Rem AI is that the 22/243 AI is absolutely maxed out with some loss of primer pockets with the 75's at 3650(guys I know are shooting 3550 for this reason), while the 22/6 Rem AI is mid throttle shooting dot size groups with the 80g A max at 3650 and not losing primer pockets and never full-length sizing. The 22/6 Rem AI is better suited on a long action of course. I had a slightly used Hart 14T benchrest barrel chambered in 22 PPC. I had the barrel rechambered to 22/243 AI, neck turned the Win brass. 60g Sierra hp at 4000 out of that now 23" barrel shoots dot size groups with Winchester 760 being the only powder used. I have a 26" Wilson in 14T that has yet to be fired, got the barrel for $100 off of ebay. 257 Weatherby with 12T, 26" shoots the 85g Nosler ballistic tips at 4130 fps on a short freebore reamer, mine was zero and another at .030 using R#19. Keeping the 22/243 AI running at max accuracy is a chore on carbon removal. Good Bronze bristle brushes and JB are going to be your friend. A famous gunsmith and barrel maker I knew, Harold Broughton, had been a Govm't Trapper in Texas. He and his wife were avid coyote hunters. His wife shot a 220 Swift with 52g Sierras and Harold in his latter years switched out to 25/06 shooting 100g Nosler ballistic tips for those "call wise" dogs that would hang up at 500. Harold told me that the coyotes could not stand his 25/06 load. Harold had reportedly killed over 5000 coyotes. From all of the 22/243 AI users that I have spoken to, figure on 800 rounds of barrel life, and I talked to one guy that did not like to clean his guns that got around 450 rounds per Bartlein barrel before they were ruined.
