All of the single shot conversions ate about the same strength. The scout brake is removable. I look at it from all angles. Even if you go to a high bc 250gr Pittman Aeromax, the max velocity from the scout still hinders you at greater than 200yd shots. With a 100yd zero, I ran some numbers.
Bullet. Muzzle v. 250yd. 300yd
250startip. 2500mv. 1500 13.2. 1400 24
250 Amax. 2500mv. 1800 11. 1700 20
Bolt gun higher pressure
275 Amax. 3000mv. 2300 6.4. 2150 11
With the conversion delivering 2500fps, you can see the startip has retained velocity of 1500fps and a 13.2" drop at 250. At 300 it retains 1400fps and has a 24" drop. That is a substantial amount of drop. Any canting of the gun will move the poi substantially left or right. You will need a bubble level on your scope and use it on every long range shot. The 250 Accumax at the same 2500 fps, as you can see, carries a little more velocity and drops a little less than the startip. However it still has drops of 11" at 250 and 20" at 300. This all adds complexity to the long shot and makes it harder to make an ethical shot.
Step up to a low end rebarrelled custom like my Black Betty. Shooting a 275 Accumax at 3000 fps, the retained velocity skyrockets, the retained energy doubles to 3200ftlb compared to the 250gr Aeromax at 2500's 1700ftlb of retained energy and the drops are cut in half. This makes the shot easier to pull off with less room for error, requiring less thought, saving time and a whole lot more knock down power out there. Ultimately, the choice is yours. Sure, the scout can do it but with a whole lot more input, thought, and a ton more preparation from you. The scout is a great gun for what it is but I'd never carry a conversion knowing I'd likely have to shoot that far.
