Looking for load data for standard 223 bolt guns with the heavier 70-80 gr. bullets. I just picked up a new Tikka t3x varmint and want to run 75-80 gr ELD-M bullets.

I am getting SD of 6 and .2-.3" groups at 100. Haven't shot for groups on paper at longer distances, but it is spot on to 800+.

Isn't the T-3 varmint available in 8 twist?
My T-3 stainless sporter is 8 twist.

I load the same 75/77gr load (24 Rl 15 w/Rem 7.5 primer and LC or Win brass) for everything.

Yes my T3-X Varmint is a 1-8 twist. That was the main reason I got it, wanted the better twist in the bolt gun for the heavy bullets.

FWIW- this information pertains to a fireforming load in a 223AI chamber. The barrel is 26" long and features a 7-twist.

73 ELD-M over 22.5 of 8208 XBR lit by a CCI 450 (Fiocchi brass) got me 2850-ish FPS with the projectile seated ~.010 into the lands. Accuracy was difficult to determine because I was also breaking in a brand-new barrel, so I was stopping, cleaning, etc..., which means that the barrel was getting warm, cooling off, clean, moderately dirty, etc...

Anyhow, the load data may be pertinent.

I have a couple of those and are stubby enough to work in my 1:8 at my elevation. I'll have to try that load.

Otherwise I have had success with
1:8 24" bolt gun
77SMK and 77 Nolser Custom Competition
26gr of Varget (crunching powder kernels)
CCI 450
2.290" OAL (at the lands in a Manson SAAMI .223Rem reamer)
Runs close to 3000fps and .5 MOA at 200yds.
