Yes, i have found the 300g Deep Curl bullet to work just fine at rifle velocities. Another bullet that works good at rifle velocities is the 270g Deep Curl bullet. In my opinion, both these bullet are superior to them Shockwave.

Following is a photo of what the 300g Deep Curl bullet looks like after being captured in water filled jugs at 60', 200 yard, and 300 yard. Powder charge was 105g Blackhorn for the 60' capture, and the 200 yard capture. The bullet captured at 300 yard was propelled by 110g Blackhorn powder.
