Mark V Accumark owners in large Weatherby calibers consistently note the long 28-inch barrel helps wring full velocity out of the 338-378 chambering. The left-hand action is a meaningful selling point for southpaw shooters who have few options in this power class.

The black and gray web stock gets mixed reactions. Some owners find the pattern attractive; others consider it dated compared to current chassis and synthetic stock designs. Fit and finish on the Mark V action itself draws few complaints.

Recoil in 338-378 Weatherby is substantial, and some owners feel the stock could use more padding at the butt. The Accumark is seen as a capable long-range hunting platform, though the recoil management discussion is the most common thread in owner feedback.
