The Rimfire Report: Winchester Super-X Power Point 40gr RNHP

 

Hello and welcome back to another edition of The Rimfire Report! This ongoing series is all about the rimfire firearm world and all of its rich history, cool stories, unique firearms, and of course its many different varieties of ammunition. This week we’re back again with another ammunition test featuring Winchester’s Super-X Power Point 40 grain Round Nose Copper Plated Hollow Points (what a mouthful). Today we’ll go through my standard set of tests using my Bergara B14R as the test platform, and my Garmin Xero C1 Pro Chronograph as our velocity testing equipment. Let’s see what this ammo can do!

Since 1922, Super-X ammunition has provided exceptional quality and outstanding performance for all types of hunters and shooters who rely on its time-proven dependability backed by legendary excellence.

Copper Plated for Reduced FoulingGreat Hunting RoundHighly AccurateUnique Power-Point Design Hollow Point for Maximum Expansion

Winchester isn’t typically an ammunition option I’ve ever really tried to explore for my rimfire exploits other than for plinking ammo. Winchester does indeed have a  bulk version of this ammo and it seems fairly identical in performance and design other than the price. You can expect to pay around $0.08 per round for the bulk stuff while the 100-round sleeve I picked up costs just a touch less than a sleeve of CCI Mini-Mags at $12.00 per box in the store. This is another one of those ammos that I have an easier time finding in stores rather than online.

The rounds themselves are fairly uniform in shape, the copper plating seems even as do the rather unique round-nose hollow point tips. I presume the round-nose bullet design is there to help mitigate some of the feeding problems you typically run into with hollow-point ammunition. While I didn’t bring any gel blocks to the range today – we’ll revisit this ammunition to do some expansion and penetration tests as it does seem like its main goal is to serve as a high-velocity pest control or varmint hunting round. Now on to our standard set of tests.

You’ll notice some shaved-off bullet inside of my action – the previous round before this got hung up on the chamber and cut off a piece of the bullet.

Velocity Data

I initially wasn’t expecting much from this ammo as I’d only ever encountered the bulk variant of it. As opposed to the bulk stuff that is covered in a thick wax – the rounds that come in the sleeves are much cleaner and appear to be unlubed, probably relying on the copper plating for lubricity. However, the velocity data was pretty promising with the standard deviation only rising up to 11.6 fps, while the extreme spread was at 47.3 fps. All rounds fired were supersonic at the barrel which is a good thing as it’s advertised at around 1280 fps – well beyond the supersonic threshold and probably fast enough to keep that ammo supersonic for about 75 yards.

I find the standard deviation most impressive in this particular data set. As I’ve said before, the extreme spread is a good indicator of what you can plausibly expect to happen, but your standard deviation will give you better data overall for shot-to-shot consistency, which directly translates to downrange accuracy and group size. 11.6 fps of standard deviation is pretty good and should also theoretically yield some good accuracy results.

After learning that the ammo patterned about 3” to the right, I decided to correct it after the first group. Perhaps a bit of an overzealous correction.

Accuracy Data

Similar to the S&B Club ammo, Winchester’s Super-X Power Points seem to do quite well out of the Bergara B14R. While not quite as accurate, the Super Sonic Power Points definitely have both the power and the accuracy to be considered a serious option for rimfire varmint and small game hunters.

Groups 1 and 2 – you can cleanly count 10 impacts on the left group with the right group being mostly one hole with 3 distinct outliers.
Group 3
Group 4
Group 5

The smallest group I was able to put together using my rig measured just a hair over an inch in size with 8 out of the 10 shots landing within a ½” wide area. Three out of five of the groups I would consider pretty good while the first (top left) and last group (center) were about twice as wide as the good ones (about 2 inches). To sum it up, I think this ammo is pretty accurate – especially for a supersonic varmint hunting round. I’d be more than confident with it on a groundhog or prairie dog hunting excursion.

Matching A Suppressor

In our modern times, there really is no reason to not put a suppressor on a long gun. Not only are you saving yourself a lot of hearing damage, but you’re also giving yourself a better shooting environment with a much smaller report which should allow you to stay on target with less effort. When I shoot the B14R, I almost always use my TiOn Inc Dragoon 450B Suppressor, but this is honestly overkill as the B14R’s main mission is to be an extremely heavy and stable precision platform – not great for the dynamic nature of hunting small game.

A much more practical solution would be to use an appropriate size rifle and suppressor and if I had my pick for this job, it would probably be a Ruger American Rimfire with a synthetic stock, a simple Leupold Rimfire scope, and an  AB Suppressor Little Bird. The Little Bird is the most popular offering from AB. I like the Little Bird because it’s insanely light while still giving you a fairly large internal volume since it doesn’t use baffle spacers. It’s still user serviceable and it’s got a great tone to it even when paired with supersonic ammunition. Best of all, it’s one of the more affordable options out there at only $320. The only major downside to it is that it’s a little on the longer side, which is why I’d probably slate it for use as either a tucked suppressor or for a setup where I’m optimizing for a budget.

Final Thoughts

I was pleasantly surprised by the performance of the Winchester Super-X RNHP. I’ve had a lot of problems with various types of bulk and performance Winchester ammo in the past but this particular offering through the Bergara B14R just seems to work great. It’s accurate, consistent, and best of all affordable. I think I can solidly recommend it for those who are looking for a cheap, high-velocity cartridge that’s also affordable. Once again, I’m just a sample size of one and you could be having completely different results than me! Let me know what you think of this ammo and what other types of rimfire ammo you’d like to see tested here. Thanks as always for stopping by to read.
