i have shot several deer with a barnes bullet as well as my hunting partners. we have only recovered 3 bullets the rest ended up in the dirt. i have never seen or heard of a lack of penetration because of prontal surface on a barnes bullet. now the accuracy of a barnes bullet is not as great as say a shockwave in my experience. i assume it's due to the lack of setback in the barrelupon firing. but for shots within say 125yds this minor lack of accuracy is not an issue as long as your shot is steady and you do you job.
