If you look back at one of my posts I asked the same question. After mutiple powders and bullets I have found the one that is great in my gun. I'm using 66gr. of reloader 22 with 150 gr nosler partitions. I was all over the place when I first started (8-10" groups) but now have a great load that shoots 1" groups at 100 yds. It's worth trying different brands of powders...most people suggested IMR but as soon as I used R22 almost everything I shot out of my gun was grouping well. From that, I tried different bullets and now will play with seting depth. Good luck! JDinAB

Your best group size is acceptable, but the fact that you cannot get this size consistently may not be. It all depends on how much larger the groups tend to be. IF 99% of your shots stay within say 1.25" @ 100 yards, and 2.5" or less at 200 yards, your rifle is shooting plenty well enough for hunting.

(BTW, both IMR 4350 and IMR 4831 are on the fast side in the 7 Mag. I find H4831, RE 22, and IMR 7828 all better suited in it with bullets over 150 grains in weight!)

I hope this helps you out Mossy33oak 'cause you reminded me of that guy i the commercial who was tired of cleaning his "old style" muzzleloader and cleared the table off with his arm and then threw it in the trash can. lol

I have had excellent results in several calibers and different weight bullets using the Most accurate powder tested and the most accurate load within that powder, in the Nosler 5th edition reloading manual. The manual calls for Viht N165 pwder at 61 grains (which is also the max load).

I also agree that a rework on the trigger or a reolacement trigger is a good idea.

Yep, you are being picky. Your groups are good. The trigger will be a welcome relief.
Load work ups can be very frustrating. You can shoot many rounds without seeing the results you want. A man named Audette came up with a good method. Load your choice of powder/bullets for a particular test. Load 15 rounds total. Load the 1rst 3 rounds at the minimum listed load for your bullet/powder combination. Load the remaining 12 in equal increments to the maximum listed load.
Go past the grocery store and pick up some large white posterboard. Put a large target dot in the center. If you can, set the target at least 200 yards out. Shoot the 1rst 3 minimum loads to see were you are hitting. You want to be starting out 2" or 3" below the bullseye while aiming at the bullseye because your hits will tend to rise as you advance thru the loads. This is the time to make any corrections. Mark your 1rst hits, and number each successive hit, as often as necessary to keep track of them. If you have access to a chrono, use that too.
Keep your point of aim on the bullseye and shoot your loads, while keeping track of your hits and keeping your eye open for any signs of excessive pressure. Record your data for each test. Keep your target for each test. You will need to evaluate it later.
You are accomplishing several things here. Your shots should start to string up, as your loads increase. You will notice that some of the shots will group together, then start stringing again. The grouping indicates a sweet spot in your load, a spot for you to work on. There may be more than 1 sweet spot. You are only shooting 15 rounds, but you can tell if the bullet/powder combo has potential or not. You are also safely working up to the listed max load when you use the Audette method.
There is really a lot you can do to fine tune your loads. I would suggest you avoid CCI primers in your 7 mag. Also, I would start my O.A.L. .010" from the lands, tune your O.A.L. after you find your load.
Check out Varmint Als reloading page
There is a whole bunch of info for you there.

1mile50,
Just wondering why you suggest avoiding CCI primers.

I have a blue Model 77, Mark II in 7 Rem Mag. When I 1rst started loading for it, I used CCIs, got several misfires from them and only from them. I have had issues with CCI primers in other calibers, too. I prefer Winchester primers, but some folks swear by Federal. Winchester primers are definately preferable for hard to ignite ball powders. Ball powders were initially developed by Olin. Olin formulated their Winchester primers for their powder. Heavy loads in big cases also require highly reliable, consistently hot ignition.

I second that on the CCI primers as a primarily handgun cartridge reloader, when I first started reloading I used CCI primers aswell for 357 magnum, 38 special and 45 acp. With factory hammer springs I missfired about 2 in 50 shots, one missfire in a centerfire is too much. then with my revolver I used a softer hammer spring to help me from jerking while shooting double action, Now I was having atleast 10 misfires in 50 rounds. So initially I switched to federal primers since they are the easiest to detonate, Then later I started using winchester b/c their cheaper. I later found out that CCI often would subcontract primer orders to other companies and not always would they make the primers by CCI's standards and often would reflect in deffective primers. And cci also uses a harder alloy in their primers. To me cci is just strange anyway look at their factory ammo aluminum non reloadable cases with different then conventional priming.
