22LR Supersonic Ammunition Accuracy Comparison

“You can't always get what you want
But if you try sometimes
You get what you need!”

Keith Richards & Mick Jagger weren’t sing about ammunition supplies, but over the past couple of years that is exactly the situation.

An example of that is not being able to get CCI 40grn HP Subsonic for my Ruger 10/20 and having to use CCI 40grn Standard Target Solids.

But as you will be aware the “Slow Boat From China” (via America) came in a month or so ago, bringing stock to retail & now we are spoilt for choose, at least until the tide goes out again!

Before investing in a few thousand rounds I decided to do an accuracy test to see which high velocity round is suited to my Weihrauch HW60J. Rather than test every known Brand, I limited my choice to one supplier, who stocks Browning and Winchester:

1. Winchester 555 36grn HP Segmented @ 1280ft/sec
2. Winchester Super X 40grn HP @ 1300ft/sec
3. Browning BPR 40grn HP @ 1435ft/sec
4. Winchester Super Speed 40grn SOLID @ 1265ft/sec
5. Winchester Power Point 40grn HP @ 1280ft/sec
6. Winchester 555 36grn HP Segmented @ 1280ft/sec

Out in a farmers paddock I set up targets numbered 1 – 6 to correspond with the above list, at 30 odd metres & 75 metres. In the event I ran out of time and only shot the short range, but the results were pretty conclusive.

The target were shot with one round only, in sequence from 1- 6, with 60 seconds on barrel cooling time (action open) between shots, so as to avoid heat build-up & ensure the barrel was a consistent temperature throughout. That’s why I ran out of time….

My expectation was that each type would shot a 5 shot group (Because we all know that three shot groups are meaningless!) which would be thumb print sized……Not so…..

Results listed from tightest group, to biggest group:

1. Winchester Power Point 40grn HP @ 1280ft/sec 12mm
2. Browning BPR 40grn HP @ 1435ft/sec 20mm
3. Winchester Super Speed 40grn SOLID @ 1265ft/sec 22mm
4. Winchester Super X 40grn HP @ 1300ft/sec 28mm
5. Equal: Winchester 555 36grn HP Segmented @ 1280ft/sec / Winchester 555 36grn HP Segmented @ 1280ft/sec 30mm

Needless to say I have purchased and few thousand rounds of Winchester Power Point 40grn HP @ 1280ft/sec which I have been using for the past month & am very happy with the results.

NOTE – DISCLAIMER: These are the results which I achieved with my rifle, with my shooting technique. The results which you achieve with your rifle may differ, but the general principle of trying different Brands & Weights to see what best suits your rifle holds true for both rimfire & centre fire. Also note that there can be variations between manufactured batches, so the ammunition you buy in 12 months time may shoot differently to the ammunition you test this month.
