I agree with the comments above. Something is wrong but not enough data to give you much guidance. A Creedmoor usually shoots better than this right out of the box but we did see an AR10 6.5 CM at the range this summer that shot groups like that with several brands of ammo.
Bolt or semi-auto?
Who is the manufacturer and length of barrel?
What is the SD, ES and average fps for each of these groups?
Do you have a way to measure bullet runout?
New brass or shot how many times?
How was the barrel broke in?
How many rounds through the barrel?
I posted a picture a couple weeks ago of my new Ruger Precision Gen 2 with a 5 shot group that could be covered with a nickel at 100 yards. Nosler second firing brass, 40.0 grains of IMR4350, Federal primer, Hornady 140 grain ELD-M with COAL as recommended in the Hornady Reloading Manual. Started at the minimum recommended load and incremented in 0.3 grain increments until I started to feel a slight stiff bolt lift which was at 41.5 grains. It has been too cold to get back out to try some different seating depths but pleased with where it is currently so will probably save my reloading supplies.
Hope everyone had a wonderful Thanksgiving. Even though our nation has some problems, this is still the best place in the World to live and raise a family. Seeing lots of Black Friday ads to spend our money on …..but still lacking primers.
