115 Tubb in a SAMI .243

[chuckw2]

Has anyone loaded this bullet in a .243,no molly)? I am currently loading 107 match kings and 105 Laupas for 600 and 1000 yards with 37.4 H4350,BR-2, Laupa case. The Tubb 6mm has a much better BC than the 105 or the 107's.

Bob Blane, any experience?

Hi Chuck,

This is one that I have not had any experience with yet. I am planning to try them, along with the Berger 115gr. VLD's, but with the weather as it is, it will have to wait until Spring. I will be trying them in my upcoming 6/284 that is wearing a Douglas 8" twist that I had Dan Dowling put together for me. I still have to get it stocked, but that is coming down to a couple of choices that I will have to work with soon. I am hoping that some of the others, that have had a chance to try these bullets, could lend a hand with some input. Perhaps David Tubb might help us with some of his insight on these bullets. Are you watching this one David??

Cordially,
Bob Blaine

Bob,
There have been a large number of shooters have success with a true 8 twist barrel and the DTAC 115. The Berger will need a faster twist and still doesnt shoot very well,"bullet design" HBC says)
I still prefer the 7.5 twist as I feel it shoots not only the 115 DTAC but also the 107 Sierra better.
I believe HBC was using a 7 twist rifle when he shot the small group with the 115 DTAC.
I have also tested the 115 DTAC out of a 6.7 twist and they worked just fine out to 1600 yards.

Hi David,

Thanks for the information! What you are saying about a "true" 8" twist barrel confirms what I have suspected for some time. With what I have been learning about cut rifle barrels, I will not be to surprised if my 8" Douglas would not perform with the 115gr. bullets. I hope that David's post will help the rest of you with the 115gr bullet.

Cordially,
Bob Blaine

I agree with David that the 115 works fine in an 8" twist barrel. My experience has shown that out to 600 yards the 8" twist is fine. This is in a Kreiger and in a Schneider, both in 6XC. Currently I am shooting a 7.5 twist barrel and the accuracy is even better. However, the 8" twist barrel still gave me 1/2 MOA out to 600 yards.

I also agree that the Berger doesn't shoot as well if at all. I have never gotten that bullet to shoot acceptably. I have tried and given up on it. The 115 DTAC is the way to go.
