Last I checked, despite the 300WM twist getting updated to 1:10 recently, the WSM's still come 1:11. I had a 300 WSM Tikka for a bit. It liked 200 grn ELD-X's. It's now a 6.5 PRC, which are also available in OEM giese.
Was it pretty slow compared to what it should have been?
I have a Tikka 300 WM with a 1:10” twist. I don’t have the mag length to load VLDs above 200 gr efficiently anyway so it is a moot point with the Tikka. Hornady prints a twist rate of 1:10” on the 200 gr ELD-X bullet box. However most of my hunting and the range is above 7000ft so 1:11” would probably work just fine for me.
Would you be able to load like 185s and have room to play with seating depth?
Probably not…but the shorter the bullet the more space for powder. I would just load the 300 WM up to a coal of 3.36” and shoot them. Either you get good groups and enough velocity or you don’t.
No. Very similar to 1:10 - 300WSM's I had. If anything it should be a tiny bit faster with the slower twist, but it wasn't enough to make anything out of it. I ran the WSM's in MT long action mags.
I haven't had any accuracy issues running anything at 3.36 in OEM Tikkas.
Yes
As simple as that? Is this true for any of the calibers that I mentioned?
Pretty much. As long as the bolt face and stop are right for the chosen cartridge, and you have the right mags, you'll be gtg.
Nice! Now I need to decide on a caliber and what type of barrel to go with.
I have a soft spot for 300 WM's. I have owned 5 or 6 over the years and I currently have 2. Used a very accurate one to assist with crop damage work over a period of years, so probably took the most game with that caliber as well.
Oh, you don’t have to sell me on the attributes. I’m just saying, if one already had a WM I don’t know if the juice is worth the squeeze to change.
