[QUOTE="Ridge Runner, post: 174387, member: 951"] My 6.5 Gibbs has a tight neck, well tighter than I like them, case life is dismal, a PITA to for cases for but it shoots like a house-a-fire, velocity is a lil low I think (3280 fps with a 139 lapua/29.5" barrel) the only way I've successfully made cases is to use unique/cormeal/tp, then they are good for 1 firing (lose the pocket) I fireform, turn necks to .010 then load. The guy who built its instructions were, resize to a crush fit, load with 54 gr of IMR 4831 behind any 140 gr. first batch or rem cases were fair. His next instruction was load with 62 gr of re-22 and a 140 (first round blew primer broke extractor) so I turned the necks but still lost the pockets after 1 firing. cut the charge back to 60 gr using CM/TP fireformed new win cases, lost the pockets after 1 firing. Got 100 new nosler cases, the smith told me I was swelling the pockets with cornmeal, so necked to a crush fit loaded the 54 gr 4831 behind a 140fired 9 cases the 10th blew the primer, broke the extractor, the first 9 were ruined also. Now my question, will opening up the throat help this? if so what will it do to velocity? not holding anyone to anything just wanted to hear experienced opinions. loaded unturned outside neck dia is .289 turned loaded outside neck dia is .285 fired turned neck dia is .288 fired unturned outside neck dia is .290 also had it shooting decent with H-1000, but went up to 67 gr with no signs of pressure at about 3220 fps, but max load is sposed to be 62 gr. Am I expecting too much or is 62 gr of re-22 too hot for this cartridge? thanx JS [/QUOTE]
