[QUOTE="Tac-O, post: 2241205, member: 109994"] Finally got my rifle back a week or so ago. He polished the inside of the chamber again and throated it longer to seat my 180gr bullet right on the lands as shown. The base of it is right around the shoulder/neck junction. The throating reamer he used is wayyy smoother than the 30-284 reamer he originally used. Unfortunately it didn't remove all of the chatter mark looking ridges, only about half. [ATTACH type="full"]285500[/ATTACH] Since my laminate stock is cracked right behind the screw holes, I widened the barrel channel in my factory stock to accept the new barrel and used it. I didn't have good expectations of it though because I'd replaced the recoil lug awhile back and I thought it didn't seem to seat quite right. After a 3 shots of break-in, I got tired of cleaning and just shot. I shot 6 of one load and 1 each of 4 other loads before calling it on that stock. The accuracy of the first load was very poor and poi shift from load to load was pretty wild. So I put the laminate stock back on and continued. I ended up with four 3 shot groups of different loads with the laminate stock, and accuracy was very poor. The best group was around 1" at 100. I used the remaining bit of some accurate powder I had this time rather than. The imr4451. Load: Aa4350 start at 53.0gr, increase by 0.4gr Cci200 180gr interlock Peterson 1x annealed 0.015" off lands The groups last time prior to having him lengthen the throat were much much better. I'm not sure if the accuracy was so bad just because of my laminate stock (maybe it's become less stable) or just due to the powder/load change. Another thing to point out is that I had sold my original rcbs dies and bought some Redding FL 30-284 dies Graf's had in stock. The combination of that, annealing my brass, and polishing my chamber I think has made it at least functional. but, I'm pretty sure I've only got maybe 0.001 clearance in some portions of the chamber. I measured some of my fired brass from today and it measures the same that the fired brass did prior to him polishing it. I first size some cases with my Redding dies without annealing and got the same exact dimensions I got with the rcbs dies. I only was able to size the case down by 0.001 more after annealing them. I'm sure this all sounds rambling and doesn't make sense. Anyway, I'm pretty sure my chamber is still very tight but at least I don't have a hard time chambering or extracting the cases. I bought a used Tikka walnut stock from a fella on here, so after I get it I'll load up some other powder and see how it does. Overall, that was not a great experience, but at least I can chamber rounds easily and seat a 180gr bullet out to a reasonable length. [/QUOTE]
