Why Hunters Choose the Glacier Ti (.308 Win)
Carry-Light Titanium System: The precision-machined titanium receiver and carbon construction significantly reduce weight while preserving zero and rigidity over long approaches.
Match-Grade Carbon Barrel: PROOF’s CF-wrapped, cut-rifled barrel delivers quick heat dissipation, exceptional stiffness-to-weight, and consistent harmonic behavior for sub-MOA potential with quality ammo.
Suppressor/Brake Ready: The threaded muzzle accepts a brake for recoil control or a suppressor (where legal) to manage blast and preserve awareness.
Hunt-Tough Finish: Black Cerakote® protects critical metal surfaces from abrasion and the elements—ideal for rain, snow, and brush.
Ergonomics That Work: The PROOF Hunter TFDE stock provides a rigid, weatherproof shell with geometry that tracks straight on bags and supports natural, repeatable head position.
Optic-Ready From the Box: An integrated Picatinny rail simplifies mounting modern turrets or lightweight hunting glass.

Crossover Practice: Confirm dope on steel in the off-season, then carry the same rifle into fall with confidence.
Smart Setup Recommendations
Optics: 3–15x or 4–16x with a zero stop and dependable tracking (MOA or MRAD to suit your workflow).
Muzzle Device: Brake for recoil control on the bench; suppressor (where legal) in the field to manage blast and maintain situational awareness.
Support: Lightweight bipod, minimalist two-point sling, and a small rear bag for prone and steep-angle shots.
Ammunition: Test 165–178 gr bonded or copper for elk-class game; log velocities and groups to find your node.
Quick Accuracy Plan
Torque to Spec: Action screws, bases, and rings—use a torque wrench and witness-mark.
Chronograph & Dope: Record MV/ES/SD; build a drop card for 300/500/700+ yds at your typical density altitude.
Lot Control: Buy extra of the same factory lot when you find a grouping load.
Barrel Routine: Keep a consistent copper/carbon maintenance schedule and track cold-bore POI trends.
