Have a savage 10 in 308 that just had a barrel upgrade (22" thin -> 26" heavy fluted). I took it to the range to see how she runs and got strange results.
Setup:
Nikon scope set to 9x, stock sitting on plastic bench rest rig (whatever they're called). It was quite stable. Butt of the gun was on a sandbag that I squeezed to change POA height. I was holding way under 1moa during the shots, I normally shoot palma off my elbows and have had better groups than my test.
I brought 50 beautiful rounds of Lapua brass / H4895 / 155 SMK bullet, but forgot that they were fireformed to my old chamber! They would not fit the new gun, so I had to use a box of American Eagle factory rounds (ugh).
Scope was on tight.
The strange results:
At 100y, the first three shots were less than 1 moa, then the whole group shifted about 2" to the right and I got a tight 5 shot group (~1 moa with 1 flyer). The next run gave me similar strangeness, one shot on target, then two shots touching each other 3" to the right, then 2 shots touching 1.5" left of those.
Also, the first 10 shots left very crisp holes in the paper, but the last 10 shots left holes that were softer and more ragged.
Explanations?:
I really don't think the wind was strong enough to cause those kinds of results at 100y, it was generally blowing from directly behind me judging from the dust at the hill.
Could it be that this gun doesn't like American Eagle?
Barrel break in? It was a new, factory take-off barrel that I bought from a good supplier and had installed by Randall in Van Nuys.
What do you all think it could be?
