Finally took the 260 out to zero this morning . I had several different loads worked up and they all did pretty well. I just need to decide which way to go now to really work on one load. Three shots each at 100 yards .

Looks great. I think lapua scenars 130 grain grouped best in the one I'm familiar with. And he burned a lot of powder chasing the best load. You may want to give them a try. But what you have looks pretty darn good.

Question- Are you just selecting a load to try with each bullet, or is there a method to the loads you are trying?

When working up a load, you have to tune the ammo to the rifle. For example, you can load up 1 bullet and select one powder and try multiple powder charge weights like 41.0, 41.3, 41.6, 41.9, 42.2, etc. This will show you what the rifle will like and where the powder charge needs to be. See the target below. It's a 243 Win with a 115 DTAC shot at 300 yards. I like this target example, because it shows the perfect signs of reading the rifle and what the rifle likes. Center was Load A (the first and lowest powder charge) and showed an open group so I only shot 4 rounds. Load B low left, still open and not very tight. Load C top left is getting tighten, and stringing a little. (This stringing tells me I am approaching an accuracy node). Load D top right, shoots very tight about 1" at 300 yards. I was able to dial in this bullet with 1 powder tuning the charge to the rifle.

When you pick multiple powders and bullets, and pick 1 bullet and 1 powder and powder charge at random, there's no way to see what the rifle is telling you on the accuracy node or where you can dial in that combo (bullet and powder) next with those components. All your looking at is how that certain combo does, hoping you get lucky with a group. I'd recommend selecting 1 bullet and 1 powder, and working with that one combo one at a time on tuning the load.

Just for info, for 100 gr Noslers in my 260, IMR 4064 was the go-to powder. For the 120s I used Reloader 17, but would probably switch to H4350 if I didn't have so much R17. Regardless, accuracy with the R17 was excellent.

I would start with the SAAMI spec COL, research the best powder for the calber/bullet weight you want to shoot and start in the middle of the powder range. Start working up in .2 grain increments.

I bet without much effort the gun will shoot one hole groups, Tikkas/Sakos are shooters.
If you don't get it try a different bullet.

44.5 grains H4350 (Hot but I get no pressure signs)
CCI-BR2 primer
Best 4 shot group .390" center to center
