Re: 0.7 MOA for 10-FCP-K .308
When I first got my 10fp w/accu trigge, flimsy plastic stock, with 24'' barrel I started with the 150 grain Federal fusions. I shot a few to get the scope dialed in and then shot a three shot group of about 1.5" at 100 yards, but the barrel was pretty hot by then. A little while after I left the gravel pit where I was shooting I knew I just wasn't satisfied with the group, I felt my barrel and it felt pretty cool turned around and went back I shot a three shot group just a whisker under 1 MOA . I was actually really happy and then the next I tried Prvi Partezan 150 soft points and could get .75 at 100 consistantly, but I would shoot and shoot getting blown primer's on 90 degree day's, but a few year's ago I didn't know that was from high pressure, I thought it was just cheap junk case's ???. I must say besides that Pravi ammo I've never had another blown primer, now that I reload with 1000 rounds through it I am currently using 2 pretty stout loads. I switched to the 175 grain SMK's with 44 grains of varget or 44 grain's IMR 4064, the gun has a short throat as a side note. The Varget load is average of 2650 fps and 4064 is 2680, .5 or less five shot groups at 100. I have shot some really really great groups with this rifle, the best 3 shot was .018 but I have been able to hover in the .3 range but it takes demanding consistency in shooting these groups, at least for me.

I could not figure out how to put a picture in here, you have to look way back and to the right to see a little white of the target
Re: 0.7 MOA for 10-FCP-K .308
That sure is an awesome build you've got there Frank :o. Would you be so kind to give detailed rifle spec's and load spec's, great shooting! I've been thinking about building a 30BR myself for short range F-class.

Dansavage thank you, I hope to do better tommorow when I go to a real range and a nice fixed bench.
wells it a krieger barrel 1/17 twist and .330 neck, 25 inches long a leupold 45x scope, mcmillan edge stock, and a savage target action, barrel and action work done by Lester Bruno, I loaded 34.4 grs of H4198 and I use Ronnie Cheeks 118-9 ogive bullets and that target were shot with a .010 jump, I been shooting at the lands , just happen to try this today, going to do one more test tommorow, got to get ready match on Sunday, I shoot this gun in VFS Varmit for score it is a 100 and 200 yard game.
Should you build one you have to turn necks down to .010 thickness then use a .324 bushing that will give a loaded round of .329.
make sure they use the robinet reamer 0 freebore, if you want to do a drop in shilen has the right reamer, I am thinking of doing another with shilen barrel same twist but in a number 7 contour and a savage varmit action with DBM I have one in a 6mm br I can just swap barrels same go-gage.

100 yards is usually used as the minimum to calculate MOA for high powered rifles since it is long enough that most bullets will have stabilized in 100 yards.
And the particular conditions you hunt under have nothing to do with the calculation of accuracy, they just have to do with the minimum acceptable accuracy which is an opinion not a measurement.
There is much more than the shooter that changes at long distance. Environmental changes have a bigger impact on trajectory than anything else.
100 yards usually is, but not all the time. Most of my shooting is done at longer distances. I wouldn't waste my time shooting my 338 Edge at anything less than 400 yards.
Many of the bullets I shoot take longer to stabilize than 100 yards.

MOA is a measurement of angle not a measurement of accuracy.
Are you saying that you get 7" groups at 1000 yards? Or, that it should because you get .7 at 100 yards?
Re: 0.7 MOA for 10-FCP-K .308
What I am saying with all things being equal .7" at 100 yards = 7.0" at 1000 yards.
Re: 0.7 MOA for 10-FCP-K .308
sliderspal, true, .7 would be 7 at 1000, I think the point some are making is it never works out that way, just because you shoot a .7 at 100 it is doubtful that will happen at 1000, I would be willing to bet it will not happen to many factors involved, that is why when you posted the .7 everyone asked how far, your heart rate alone will change bullet drift, example at 200 yards with my F class 6mm br i shoot it 1/4 moa and less at 600 i average 1/2 moa and only on my best day and only twice have i come close to 1/4 moa with a 2.2 inch group only once that =.350 moa and 7 inches at 1000 yards =.668 moa as well at 100, I think that was the point trying to be made.
