Looking for powder recommendations for 223 69 gr smk bullet with 1:10 twist

[bichettereds]

I've had good success with Varget and Reloader 15 and that bullet in a 1:9 and 1:8.

I've had good luck with ramshot tac in my ar. Accurate as varget but more velocity.

I run CFE.223 with a 68 Hornaday bthp match bullet. It is very good at 500-600 yards.

I have your exact same rifle; Tikka T3 lite .223 - 22.5" 1/10 twist. I also shoot Sierra 69 gr Matchkings. My accuracy node was found at 23.2 gr of XBR 8208 using LC brass, CCI 400 and a 2.255 OAL. This load is a little on the slow side but yields me 2700 fps. I like XBR 8208 with this bullet in that I do not have to worry about a compressed load.

I did attempt to try the 69 gr Tipped Matchkings and they were no dice. They are longer than the original Matchkings and would not stabilize in the 1/10 twist.

Since we have the same rifle, I thought I'd share one other load. I have also developed a load for the 50gr Sierra Blitzkings. 26.4 gr of Benchmark yielded the best accuracy.

I've used a ton of powders for 223/556 and I always fall back to 8208/Varget.

I have had very good luck with the SMK 52 hpbt, 24.3 grains of Benchmark powder and CCI400 primers using Lapua brass, velocity at around 3050 fps. I wanted to get out farther so that is why I am trying out the 69 grain. Crossing my fingers it will be stable in a 1:10 twist and hoping to get 3100 fps.

I use Tac also and have good luck in my m4 also , but there is alot better for accuracy out there but tac will push a .223 bullet very fast... If you look at their reloading data , a free download , you will see how much they say is safe compared to the manuals you will be shocked...

25.3 Varget (mag length) . A drop tube will help . 2825fps from a 20" Howa varminter .

Might consider VVN140 at around 24grs, plus or minus a few tenths. I don't have or load for a Tikka so I haven't a clue what your rifle likes in a .223. But my AR's and bolt .223 like the V140 pushing 69gr Sierras.

H4895 worked great for me.

 

[dolek]

Another vote for H4895 .

I also find 25.3 grains of Varget to do the trick with 69 grain SMK's. Shoots very well in both a 1 in 9 Savage bolt gun, and a 1 in 8 AR.

 

[Rodney]

I’ve had good luck with ar-comp. Usually one grain less than varget would give me the same velocity as varget.

 

[Mastershot]

25.3 varget set at mag length work great for my ar with a match barrel.

The Sierra manual actually lists Viht N540 as the accuracy powder for 69 gr. Match Kings in .223 bolt rifles.

I load it in Lapua cases with Rem. 7 1/2 primers and obtain high levels of precision.

N540 is expensive, so you may want to experiment with other powders.

 

[Lonewolf74]

Not meaning to hyjack hear but I'm playing around with this same bullet in my AR.

So my question is about where should velocities be with this bullet out of a 16" barrel?

I've ran them up to 2900 fps out of my AR but it seems accuracy fades after 2800 fps. And I have yet to find what I would consider great accuracy

My Winchester Mod 70 with a 26" 1/9 twist likes 69gr SMK with Lapua brass using 24.5grs of Varget and CCI-450 primers.
