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.

Solid 1/2 moa load. Also took it to 996 yards today. BC seems higher than published.

.250 G7 lined up for me. Velocity measured with a LabRadar.

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.

Starting to think my rifle doesn’t shoot. Tried both Varget and 8208 and 80eldm. SDs are low single digits but accuracy only 3/4 MOA. Full custom build.

Any recommendations on another powder to try?

I just loaded up some 80.5 Berger fullbore. I was really hoping to shoot the 80eldms because I have a bunch of them and they had been very flat shooting at distance with my last bolt gun.

If your velocity is that consistent but the load isn't grouping well, it maybe worth taking some time to play with seating depth.

I guess I’ll have to try new bullets. Just shot some 80.5 bergers as well as my DMR load with 77 TMK. Both shot .3s.

Neither of them have the bc of the 80 ELDm unfortunately.
