After many sessions of load development I shot this group the day. I am shooting my 7-08 with 24" Krieger barrel using 42gr of MR2000 under a 162gr Amax. Is this considered an average group or a good group for 300yd. I shot these off bench with a bipod. I'm just learning this long range game.

1.35 in. is not bad for 300. I predict you can close that group up with a little judicious critiquing of your platform and body positioning, npa, etc. Try more than 3 shots to arrive at a better average of what your barrel and load is capable of.
 
3 shots is a good starting point to narrow down loads, but its better like 40xs said to shot 5-10 shot groups to see the load and the rifles capabilities
 
That is a very good start to qualify your potential. As mentioned more shots tell the story. I was satisfied until I practiced to shoot my first Fclass match at 300yd, with three relays of 20 shots each; and I learned it is much more difficult to get good groups of 10-20 shots. Now instead of practicing with a number of 3-shot groups, I shoot a few 10-shot groups which develops you skills more quickly because it forces you to concentrate better and put together good habits as a consequence. It is easier to dismiss a bad 3-shot group and like the others, than it is to dismiss 1 bad shot out of a string of 10. At least that's how it has worked for me. Good luck and good shooting.
 
A little under .5 MOA would keep me happy. I understand stopping after 3 and calling it a day.

My problem is I show off and go for five rounds with the 5th shot blowing the whole thing up creating a two MOA result.


Edit - my assumption is 1.35" is the measurement of shot holes shown, you havent already divided by 3 for MOA. If you did already bring it down to MOA a little over 1.25 inch still makes you better than most shooters at my club.

Thanks for the responses guys. I will take your suggestions and build on that. I haven't even tried prone yet. I am hoping the load and bullet combination will hold up. My skill level at this point needs a lot of work. I was shooting with a SS 3-15x44 but I just changed to a Sightron 8-32 x 56. Hopefully that will help with more precise aiming.
 
Im rolling into my range right now to do some 300 yd load developement. If I think of it Ill come back with a pic of this fakers ability.
 
I may not be the best person to judge where you stand but your question is one Ive pondered......

300 Yards. 4 loadings.



Target 1 - 5 rounds from the magazine 42.6 grains IMR 4064, 168 Nosler CC.



The above target was a warm up using a round I am testing for my LMT AR. It was not one I expected to shoot well in this rifle. After this group I made a scope adjustment 1/4 MOA and .5 MOA RIGHT - Yes calling me a retard is slander to retards.

The next targets were fired round robin - 1 round each target of each loading.

41.8 grains IMR 4064. Upon seeing shot 1 far right I adjusted left 1MOA. 9 rounds.



43 grains IMR 4064. I expected this to be my best load. God I hate load developement. 10 rounds



44.2 grains IMR 4064 9 rounds.



The measuring device sucks but you get an idea. Not getting the results I expected. I like what 41.8 was doing and it only started to drop toward the end of my firing when fatigue and rifle conditions changed. Had I not done my 2R windage change the first five shots would have made a very nice group, 6,7,8,9 are all dropping from the knot.

Anyway I hope this helps. No matter how good you become I hope I have shown you that stupid kills skill.

Nice shooting pm, what was the wind?

What about 42.6? What's wrong with it?

The flag was hanging limp like Liberaces pecker when watching a lesbian porn.

There is nothing wrong with 42.6 and that is my conundrum.

I have a post on here regards my OCW work and I have groups that do great at 100 than I get different results at 300. 43 was great at 100, POI was consistent with groups lower/higher but in practical app something else outshoots it. 42.6 worked well in my LMT if it consistently works well in the M40A1 Id be well pleased to load one round for both.

Ill probably update that original OCW post with my 300 results and see what the collective brain suggests.
 
OP, if you are just beginning you are doing well. I like the 7 and wish I had some of those 150's to try myself. You using a brake?

No I'm not using a brake and thanks for the encouragement. I talked to nosler the other day and said that production would start up on them in December. They shoot well in my gun with Varget and IMR 4064. I need to chronograph them asap.
 
OP sorry if my posts have lead to some "drift". Intent was to give you an idea of someone elses 300 yard results.

Varget is my 30-06 powder and I really should try it in my .308 but I just detest screwing with load development. I just want that one load that will shoot well enough and will allow me to work on my fundamental issues. 4064 just seems easier to come by also.

Your shooting looks great. If you are liking Nosler products make sure you are checking the Shooters Pro Shop. Primarily all I load is their "seconds" in .30 cal and .224. I probably deal with a bunch of tolerance stacking in my shooting - load on progressive, use a balance scale by eyeball, win LR primers, sorted range brass, and seconds for bullets - oh well its all fun.

As for your load work I always do 3 shot load development testing. Three the load five are the shooter. Some may agree and many will not agree. But it's worked for me for many years. Depending on what you're wanting to accomplish with your rifle that may work. My shooting platform though I have to strive for sub 1/2" at 300 yards for load development and I want to strive and find loads that'll shoot at 1" at 500 yards.
Typically once I find my load I tweak seating depths to find the optimum seating depth. Once that's done I'll test 10 3 shot groups for consistency.
 
No problem pm. I like input from others. How do I find this Shooters pro shop?

Google "Nosler Shooters Pro Shop"

When you are on the site in the menu bar up top hit Nosler Products.

From the drop down menu

Factory Seconds.

The also sell firsts and over runs in there. Prices are pretty good.

James that is some really good shooting to achieve those goals. At my level, I cannot expect those results, but only strive for them. I just mounted a Sightron 8-32x56 on the rifle. I felt the 3-15 SS was limiting me to shooting groups at longer ranges. With larger targets it was fine. I also haven't perfected my shooting technique. Lot to learn. Where in TN are you located?
 
I'm in Shelbyville, and I do agree the scope probably was limiting you on your accuracy. As the saying is in group shooting aim small shoot small. So more magnifications and a smaller aiming point will also allow you to achieve smaller groups. Loading technique and rifle handling is another factor and then you need wind flags for that final piece of the puzzle.
