This project came into being a little fast than expected. It's part of the "what if bug".

I have not had a chance to stretch it out to 200 yards yet, maybe this weekend.
When compared to the 458 Win Mag in a 14? barrel, the Lott runs about 250fs faster.
I have not tested any bullet weight heavier than 350 grains.

Conclusion:
Accuracy excellent.
The weight of the Encore and fish gill brake do a great job taming the recoil which is a little brisk but fun to shoot.

Good shooting
