I’ve been getting into reloading for my 6mm BR and recently picked up some Berger 68 grain flat-based bullets. I’ve seen a lot of talk about how critical the twist rate is for achieving accuracy with these bullets, but there seems to be varying opinions.
Key Questions:
What is the optimal twist rate for the Berger 68 grain FB?
Are there specific barrel lengths or other factors to consider?
What has been your experience with different twist rates?
Why Does Twist Rate Matter?
To get a better grasp on how twist rates impact performance with Berger bullets, it’s important to understand:
Stability of Bullets: A proper twist stabilizes the bullet during flight, which can drastically affect accuracy.
Barrel Length Influence: How does the length of the barrel affect performance with these bullets? I’ve seen recommendations that vary based on barrel specs.
Your Experience: If you’ve been reloading or shooting with the Berger 68 grain, I’d love to hear your insights!
Looking for Recommendations
If anyone has load data that pairs well with these bullets and thoughts on twist rates, I’d greatly appreciate it. I’m looking to refine my setup for competitive shooting and believe the right twist rate is pivotal for getting the most out of this projectile.
Thanks in advance for sharing your wisdom and experiences!
I’ve been experimenting with different twist rates, and I found that a 1:10 twist rate works wonders for stabilizing the Berger 68 grain FB in 6mm BR. It provides excellent accuracy and stability at various distances.
As a general guideline, the faster twist rates tend to work better for heavier bullets. I’d say a 1:9 or 1:10 is ideal for the 68 grainers. What barrel length are you planning to use?
Good point! I have a 26-inch barrel, which should allow for good performance with a 1:10 twist. I’m curious if anyone faces any drop-off in accuracy with a slower twist.
In my experience, anything slower than 1:10 can start to destabilize the 68 grain FB bullets especially when shooting at longer distances. So, 1:8 or 1:9 seems to be a sweet spot for these bullets in the 6mm BR.
I’ve had a blast shooting these bullets with a 1:10 twist, but I also wonder if barrel length affects things substantially. Anyone had radically different experiences based on that?
For me, I’ve noticed that a longer barrel does help maintain velocity, which can offset potential stabilization issues with a slower twist. It’s fascinating!
Funny enough, I’ve heard of folks joking that 1:7 twist is for warriors, but it seems 1:9 and 1:10 are actually the warriors for the 68 grain flat base. Can’t wait to test it out!
When you all mention these different twist rates, it’s fun to reflect on how much precision can be impacted by just that one variable. Have any of you logged your data for comparison?
