I used 4-5 different powders too. H4831SC, RL19, IMR 4064,H4350, and IMR 4350

Have you ladder tested your loads? I would pick one or two powders and run 5 or 6 loads. Find a safe load and work up to max pressure. I'm sure you will find a node for accuracy. With the H4350 start at 58grns and work up in half grain increments to max (should be about 63.0grns. watch for pressure signs).

She says muzzle break isn't an option. Doesn't want to go deaf like me.

Just trick her, put the 180's in there tell her thier 150's. When she's shooting that big mulley she won't care.

Breaks are removable. You could practice with one on the bench. When it comes time for the hunt, take it off. Recoil is seldom felt when shooting the intended target in the woods. I can't remember any felt recoil shooting my 338WM in the woods. On the bench I always used a sand bag on my shoulder.

Anyway, the combination of a slow powder and a 160 to 180 grain bullet is not going to be all that bad and feel a little less than your WM. You don't have to load to max either.

My favorite 300WSM loads for all out tight groups at ranges out to 500yds with 150 grain and 165 grain bullets:

150 SST
70.0 Win 760
3250 fps

165 SST
68.0 Win 760
3150 fps

These loads are right from the Hornady manual. WIN 760 and IMR 4350 were Hornady's preferred powders with the 300WSM.

If that Tikka doesn't shoot Sub MOA with those two loads I would be surprised. These loads have shot spectacular with 5 different 300WSM's that I have loaded for.

Good luck Partner!

Thanks... We'll start with that.

To get more length, so you can seat your bullet farther try this. The tikka is based on a long action no matter what caliber you have so the only difference is in the magazine it has more material on the back side of the mag. To get a longer magazine / bullet length you can filedown some of the plastic on this magazine back and get the ability to seat your bullet a little further out.
