Overview
The BSA Sweet 17 SP is a 6-18x40mm rifle scope calibrated specifically for the .17 HMR, with side parallax adjustment and an elevation turret set for 17 and 20 grain loads.
Rather than a general-purpose scope, this one is built around one cartridge, with the turret markings matched to .17 HMR ballistics instead of generic MOA clicks. Reviewers consistently mention holding zero and tracking well at 100 to 200 yards, though the included mounting rings drew separate criticism as the weak point of the package.
- 6-18x40mm magnification range
- 30/30 duplex reticle
- Calibrated turret for 17gr and 20gr .17 HMR
- Waterproof, shockproof, fogproof
Who it's for
Suited to .17 HMR shooters who want a scope calibrated to their round rather than a universal reticle. Less of a fit for anyone who needs multiple rifle calibers on one scope, since the turret is matched to one cartridge.
What buyers say
From Amazon customer reviews.
Reviewers on .17 HMR rifles consistently report the scope holding zero and grouping tightly at 100 to 200 yards, with several calling it strong value for the price. The recurring complaint is the bundled mounting rings, which multiple buyers describe as the weak point compared with the scope itself. One reviewer had a unit where the elevation adjustment failed to move the point of impact, though they noted the return process was easy.
Strengths and trade-offs
Drawn from this product's published specifications.
- Turret calibrated specifically for .17 HMR loads
- Holds zero through repeated firing, per reviewers
- Side parallax adjustable from 10 yards to infinity
- Includes a sunshade
- Included rings are lower quality than scope
- Zoom ring doesn't fully reach stops at 6x/18x
- One reported unit with elevation adjustment that didn't work
Performance notes
Side parallax adjustment runs from 10 yards to infinity, letting you dial out parallax error at typical varmint ranges instead of a fixed factory setting. The elevation turret's markings are calibrated for 17 and 20 grain .17 HMR loads, so dialing to a marked yardage should put the round close to point of impact according to reviewers who tested it out to 200 yards.
