Is the Hawke Sidewinder 30 SF 4-16x50 subject to Australian electrical compliance certifications like SAA or RCM?

No, this rifle scope is completely non-mains-powered and operates optically, utilizing only a single CR2032 coin cell battery strictly to power the red reticle illumination. Therefore, it does not connect to 240V mains electricity and is exempt from SAA or RCM electrical safety compliance certifications.

How close can I focus with the side parallax wheel on this model?

The side parallax focus is adjustable from 9 metres (10 yards) out to infinity, making it exceptionally versatile for close-range pest control as well as long-range target shooting. However, any close-range shooting attempted under 9 metres will fall outside of the parallax adjustment range.

At which magnification setting are the reticle sub-tensions true on the 10x Half Mil SFP reticle?

Because this model features a Second Focal Plane (SFP) optical layout, the 1/2 mil hash and bracket sub-tensions are strictly true only at exactly 10x magnification. If you require your reticle sub-tensions to remain true across all magnification settings, you would need to consider a First Focal Plane alternative.

What rings do I need to mount this scope, and will it handle heavy centrefire or magnum recoil?

This scope requires standard 30 mm ring mounts with enough clearance for the 50 mm objective bell and the included 4-inch side-wheel. It is fully shockproof and rated for all calibres, meaning it can handle heavy magnum centrefire recoil as well as bidirectional spring-piston airgun recoil without losing zero.

How heavy is the Hawke Sidewinder 30 SF 4-16x50, and is it suitable for all-day outback stalking?

The scope alone weighs 725 g (25.6 oz), and adding the sunshade and 4-inch side-wheel brings total weight closer to 850–900 g. While this sturdy build is ideal for stationary benchrest, varmint blinds, or vehicle-based outback pest control, hunters undertaking grueling all-day mountain stalks often prefer a lighter, more compact optic.

Hawke 17250 Rifle Scope - Hawke Sidewinder 17250

The Hawke Sidewinder 30 SF 4–16×50 (Model 17250) is a long-range rifle scope built on a 30 mm mono-tube aircraft-grade aluminium chassis. Engineered with the Hawke H5 optical system, it features 18-layer fully multi-coated low-dispersion Crown glass, a 24° ultra-wide field of view (10.6–2.7 m @ 100 m), and a constant 102 mm eye relief. The scope utilises a Second Focal Plane (SFP) 10× Half Mil glass-etched reticle with six levels of red LED illumination powered by a single CR2032 battery. It is all-calibre rated to withstand magnum centrefire and bidirectional spring-piston airgun recoil, and is fully nitrogen-purged to provide waterproof, fog-proof, and shockproof performance.

Who is the Hawke Sidewinder 30 SF 4-16x50 for?

Long-range varmint and pest control hunters — Benefits from the 4–16× magnification range and 50 mm objective lens, which maximize light transmission during low-light sessions when identifying small quarry at extended distances.
Medium-to-long-range centrefire rifle hunters — Relies on 26 MRAD of total elevation and windage travel paired with a 725 g aircraft-grade aluminium 30 mm mono-tube chassis designed to hold zero through heavy centrefire recoil.
Precision Rimfire Series (PRS) competitors — Utilises the 9 m minimum parallax adjustment and 26 MRAD turret travel to dial exact elevation adjustments across varied engagement distances.
Field Target airgun shooters — Takes advantage of the 9 m to infinity side focus mechanism combined with the 4-inch index-matched wheel to assist in accurate target rangefinding.

Less suitable for: Close-range shooting under 9 m where the target falls outside the side-focus parallax range, or dynamic shooting requiring reticle holdovers across changing magnifications (where a First Focal Plane optic is better suited).
