HM,

Low node with 30" barrel is 2950, high node is 3150. Your rifle will tell you when and where it likes the velocity.

3150ish for my Nosler CC's and Hybrids in a 32". I can push them up a little harder to close to 3300fps but I don't like to go there as it will trash my brass. This is using N160 and Molly.

Only node I could find consistently was at 3120.

Re: .243 Winchester Velocity?

What powders and charge weights are you guys using to get 3000+ fps with the 105s? I'm using H1000 and 105gr A-max with great accuracy, but would like to push them a little faster if i can still retain good accuracy.

The velocity with 107 Sierra's in my 24" Barrel is 2925 FPS and apparently I haven't reached the sweet spot for the best accuracy.

2950 has been my sweet spot with 107 smks and 115 dtacs, I am sure I could find a higher node if I pushed, but I am happy being somewhat gentle to my barrel and brass
