so in my free time I have been trying to figure out why my 22-250 Rem 788 occasionally has a sticky/ hard bolt lift on extraction. THIS IS VERY UNLIKELY TO BE HOT LOADS (read on) had to add that to to help this along productively Rifle was completely factory and would occasionally stick a little with factory ammo slightly more with reloads with no real change between starting or near max loads I REBARRELED rifle to 6-250 using new hornady brass basically same thing REBARRELED again to 6 Norma dasher and very first load of 28gr varget did it then kind of randomly through the whole load work up although the dasher did stick more than the 250's had been Now the sticking never required me to stand up but you would have to hold the rifle with one hand to coax the bolt on up and out with the other So we have factory ammo and reloads in 3 different barrels with 5 brands of brass this leads me to believe I have a rifle problem. My hypothesis is this I believe I have a bolt flex issue letting the bolt "spring" a little and if so it would let the brass be slightly to long. Remember it's a rear lug setup I have never had means until now to measure my brass for headspace growth so dasher is the only one I could measure What do you guys think? Am I barking up the right tree? This is more a problem solving exercise as this rifle is just my test mule for learning on.
