6 Dasher 105s and 7 twist

[BWB]

Is there anyone running 105s out of a 7 twist Dasher barrel? What are you seeing for average velocity vs a 8 twist? Any stability issues?

Im right in the middle of working up a load with 110SMKs. So far I think 31.5 grs of H4895 is going to work. Ill be working on thw Berger 105s soon.I dont have any speeds yet. 29" 1/7 Dasher lapua cases

I have a 7 twist Brux that I have been shooting with 105 Hybrid and 110 SMK's. No issues with accuracy with the 7 twist and no apparent loss of speed due to extra twist.

I'm shooting a X-Caliber 6 BRX 7 twist using 105 Berger Hybrids, and have had no stability issues. Velocity is just under 3000.

How are you finding the 110SMKs for accuracy and ease of developing a load for? I wouldn't mind trying them down the track when it's time for a new BRA barrel, thinking 7.5 twist may be sufficient for them...

I'm shooting a 6XC and soon a 6 Dasher and wanting to run the 110's hence the 7 twist barrels but I have 5000 105 Hybrids and wanted to make sure they would run also. I didn't figure there would be much issue but you just never know.

Would you mind listing your loads?

Today, about 90% of my CF shooting is with 6 Dasher guns shooting the Berger 105gn VLD Hunting Bullets. This bullet has the highest BC in Bergers 6mm product line. Berger's recommendation for the best stability with this bullet is 7 twist. Unless your gun perfectly tuned, you may have a hard time seeing the difference on paper with the Hybrids with a 8 twist barrel. IMO, there is no reason to not follow Bergers twist recommendations for each bullet.

I'm running a 7.6 twist in my Dasher and have seen decent nodes at 2950, 2970 and 3010. I've ran 105s out of 7.3 twist 6x47s for years with no problems as well. However, I've never tried a straight 7 twist.
