Thread: Large MV variation from trueing

3. Litz G7 BC for projectile (a true independently measured BC)
4. Confirm average MV using radar

If you’re using a correctly setup radar to measure MV it’s a solid, given input and should rarely ever be changed.

Personally I’d be ditching the Accubonds and trying something else. There are much better options out there for LR.

I understand some people are using these successfully however you’re certainly not the first to have issues like this with these.

The ABLRs while over stated in BC are pretty good performers. I used them in a rem mag, 270, and 6.5x47 evn at rem. Mag speeds I shot O bull Tahr breaking both shoulders in close and didn't find limited penetration like can happen at higher speeds with eld ms. In the 6.5 they preformed great expanding reliably. I shoot the hornady due to price but the accubonds where pretty bloody good projectiles. Just liked a lot of jump vs being in the lands.
