I thought I would make this post after running in circles the last few months trying to find out what was up with my 300RUM. I had previously been shooting the 180 gr ttsx and while accurate, I was not liking the looks of the recovered bullets and I wanted to step up to a heavier bullet. I decided the 200 gr accubond would be my bullet of choice. After having gone through several different attempts and not being able to achieve acceptable accuracy I decided I would rebarrel it. Since I have a Tikka 300 WSM i decided I didnt need a second 300 mag, so I went to 338 RUM. This allowed me to jump up to 250 gr accubonds. Well, the problems persisted, just could not find a combination that was accurate enough for my liking. The gun would shoot two very close and a third about 1.5" away. The flyer was usually the second or third shot. I repeated this group multiple times and was getting very frustrated.
I had the action bedded and went to the range again yesterday. I was out of reloads so I grabbed a box of 250 gr LRX which was the only factory load locally available. I shot a 4 shot group at 100 yards and it was much worse than average. Previously, while going over the gun at the shop, my gunsmith took the bolt apart and noticed the firing pin spring was in horrible shape, he brought a spare and we swapped it out at the range. I fired another 4 shot group immediately after. I think the results speak for themselves.
I would have never believed the spring had that much to do with accuracy but I saw it happen. If anyone else is having these problems and you are using an older rifle it may be worth checking that spring.
