T-Bolt Straight-Pull Action

The defining feature of the T-Bolt is its straight-pull bolt design.

Unlike a traditional bolt-action rifle, the shooter does not lift and rotate the bolt handle. The bolt is pulled directly rearward and pushed forward.

Advantages:

• Faster cycling
• Less movement between shots
• Smooth operation from the bench or field
• Excellent for repeated varmint shots

The T-Bolt uses a bolt system designed around quick operation while maintaining strong lockup and accuracy.

.17 HMR Cartridge

The .17 Hornady Magnum Rimfire (.17 HMR) is a high-velocity rimfire cartridge designed for flat trajectories and small targets.

Typical loads:

• 17-grain bullets
• 20-grain bullets

Approximate performance:

• Muzzle velocity: roughly 2,300–2,600 fps depending on ammunition
• Very flat trajectory compared with .22 LR and .22 WMR

Best uses:

✅ Ground squirrels
✅ Prairie dogs
✅ Rabbits
✅ Small varmints
✅ Target shooting

The cartridge is valued for:

• Minimal recoil
• High accuracy potential
• Flat trajectory
• Low shooting cost compared with centerfire cartridges

Target/Varmint Barrel

The heavy barrel configuration is designed for accuracy rather than minimum weight.

Benefits:

• Better heat management
• Increased rigidity
• Reduced barrel movement during firing
• More consistent groups during extended shooting sessions

Compared with a lightweight sporter barrel:

• Heavier to carry
• More stable from a rest or bench

The Target/Varmint version has been reviewed as a precision-focused .17 HMR rifle with a heavy profile barrel and laminate stock.

---

Laminate Stock

The laminate stock is one of the rifle’s key features.

Advantages:

• High strength and stiffness
• Better resistance to humidity changes than traditional wood
• Stable bedding platform
• Attractive target-rifle appearance

The design favors:

• Bench shooting
• Bipod use
• Varmint stands
• Precision practice

Double Helix 10-Round Magazine

The T-Bolt uses Browning’s Double Helix rotary magazine.

Features:

• 10-round capacity
• Detachable design
• Compact rotary feeding system
• Reliable cartridge alignment

The magazine is designed to maintain smooth feeding while keeping the rifle’s profile slim.

---

Trigger and Accuracy Features

The T-Bolt Target/Varmint is built around precision shooting.

Important accuracy features:

• Adjustable trigger
• Rigid action
• Heavy barrel
• Stable laminate stock
• Straight-pull bolt design

The .17 HMR cartridge is particularly sensitive to ammunition choice, so the best accuracy often comes from testing several factory loads.
