[QUOTE="D.Camilleri, post: 183902, member: 2567"] These are all good ideas and will be followed up on, but I still have a question about about the throat length of a blue printed 338 RUM. I am thinking about having the smith that built this gun make a chamber casting and check the dimensions. When he built it, mine was the first barrel to be done with a new reamer. Maybe the reamer wasn't cut properly. Just talked to a friend with a factory barreled 338 RUM and he can get his bullets within .030 of the lands. I can't get within .090 of the lands and my throat isn't erroded. My factory barrel shot every bullet well before the problems started, this barrel has never shot any bullet well with the exception of the 250 gr partions. One other thing I am considering is to increase the bedding area in front of the lug, due to the fact that the chamber taper ends at a rather sharp point and changes to barrel contour and in my opinion, if the barrel was going to whip, it would start right at this transition. I just picked up a lead sled yesterday, so I can quit abusing my body with this shoulder abuser. [/QUOTE]
