Title: Stainless Steel and Accuracy
Post by: callonetta on November 07, 2015, 11:16:25 AM: I got myself a new 270 WSM rifle with a stainless steel barrel but I noticed that it hates being dirty, what I mean is, at 100 yards the first 3 shots are touching, the second string of 3 shots are 1.5 MOA after that it keeps opening up to where I basically stop shooting and call it a day for this rifle. I let the rifle cool down the barrel between shot strings. I get home and clean the sucker well and the next time a the range it will do the same thing.
Anyone experience anything similar to that?? is it the barrel??, the glass?? or just the dirt??
I have a 300 WSM, a 25-06 and an AR-15 in 7.62x39 that are not stainless steel and have no issues with their accuracy while "dirty"
Any advice??

This worked wonders on a CZ 204 that would foul out after just a few shots.

If it's not from heat, then have a gunsmith scope it.
Mine was a bad factory barrel.

I second not cleaning and go out and try again.

I went back to the range today with the dirty rifle from previous shoot last Saturday, set target...3 shots..... able to cover the holes with a quarter.......WTH?? I am flinching as I keep shooting is my guess!!! it's just a 270wsm for crying out loud!
I have no issues with my old 300wsm...I don't get it!!

Wood stock? How the bedding?

Then, I clean it and no difference in POI. I did go through a crazy break in period where I cleaned and copper cleaned after every shot for 20, then every 3rd shot for another couple boxes. After that, I never pull the copper out. I can clean it with 3-4 patches now.

Might consider a trigger job. Could be you just get off target with amount of travel.
