1:8 Tikka .243 velocities

[Timberline001]

I ended up ordering a 6 creed pre fit. As easy as the 1:8 .243 was going to be I love building tikkas.

I’ve reached pressure before I could achieve similar velocity to what I was getting out of a mild load in a same length barrel quite a few times. This .243 I’ll have to shoot unknowns loads for awhile because I don’t have access to my bench so I won’t be able to chase pressure anyways.

I shoot unknowns with 103 eldx (it’s all they had in stock last year) and they shot extremely well. I also had great luck with copper creek shooting 105 bergers and they shoot equally as good.

I love the rifle but the only downside to the 1:8 twist is you’re either reloading or buying boutique ammo if you’re wanting to get the best out of the rifle.

I can see why folks would do a 6 creed prefit over the factory fast 243 for this very reason.

Anyone have velocities with H4350 and Hornady 105 BTHP’s? The Hornady beginning load is above book max for my other two references. Curious where others have landed.

For sure. Unknown would have been my only option most of the time as my reloading bench is back home at not at school with us. That’s why I went with the creed.

I've seen a handful of posts stating they arent getting good accuracy out of the 1:8 twist 243 Tikkas. Are y'all running handloads? I'm wondering if enough tweaking y'all can make it shoot.

20” barrel loading to max mag length (M) 42.5 grains H4350 in new starline brass. 2900 ES OF 12 for 10. Had slightly sticky bolt and ejector marks at 43grains after 2nd shot (suppressed). Great accuracy at 42.5 really hoping it speeds up. I’ll know shortly and post if I see anything.

Anyone shooting a factory tikka 243 1:8 twist 20 inch barrel with UM loaded ammo? I am curious what kinda velocities you are getting with Hornady 103, 105, and 108. Thanks

40.5 gn with the 108 gives me 2910 , wouldn’t go higher or brass life is short.

No tweaking required, it shoots anything well.

I have never been able to load that high without pressure issues, Fed, Lap, ADI brass

108's an h1000. Had better accuracy with a lil lighter load though.
