[QUOTE="Bart B, post: 106959, member: 5302"] They sure have. With a .308 Win. using bullets heavier than about 160 grains they would last about 300 rounds before torquing to a bad fit in epoxy bedding. The magnums would last about 100 to 200 rounds. Some military long range rifle teams tried using 2-inch long recoil lugs on their Rem. 700 actions but that didn't help. Pillar bedding solved virtually all the problems with milder recoiling cartridges but the heavier ones may still work loose a bit. Benchresters started glueing round receivers in flat surfaced sleeves to solve the problem. But I've never seen a pillar/epoxy bedded round receiver shoot as well as a flat side/bottom one conventionally epoxy bedded when heavy bullets are used. Few people shoot well enough to tell when round receivers work a bit loose in their bedding; let's hope users of this forum do. Accuracy degrades at most about one third to one half MOA when they work loose a bit and torquing the stock screws to the "perfect" amount no longer works. [/QUOTE]
