H&N Slug HP – now available in the USA!

Shortly before the weekend I would like to send you an update concerning the H&N Slug HP in caliber .22.

The slugs have been in mass production since mid-October and now the first delivery has finished its journey over the Atlantic. Our friends at Pyramyd Air are the first ones to have them in stock but others will follow soon.

Why should you try this new H&N “pellet”?

For decades pellets have been made in the diabolo-shape. This shape has prevailed because its light weight and low friction resistance in the barrel are the best choice for "normal" air rifles. The precision up to 50m can be excellent.

Pellets in bullet shape are due to their weight and their increased frictional resistance in the barrel only suitable for strong air rifles. However, they offer a decisive advantage: the air drag is significantly lower than with a projectile in diabolo-shape which leads to a flatter trajectory and better energy retension on longer distances. In addition, they are less prone to side deviation by cross winds - a clear advantage when shooting over long distances.

Due to the development towards ever stronger air rifles and the wish to shoot precisely beyond 50m this shape becomes more and more interesting - if not even absolutely mandatory.

The idea of making a pellet in the shape of a bullet is not really new. The H&N Rabbit Magnum or the H&N Piledriver have been around for years. Especially the Piledriver with its boat-tail is characterized by an already extremely favorable BC of 0.095 (caliber .22, 30 grain). In 2014, we developed the Grizzly from the hollowpoint lead bullets that we make for powder burners since decades.

However, all three products have a decisive disadvantage: they are only available in one diameter and one weight per caliber.
The weapon manufacturers use different barrel diameters, barrel profiles, twist rates and power setups for their air rifles. Therefore, there must be a choice of diameters and weights.

Like the Grizzly, the HP Slug HP has been developed from our hollowpoint bullets. The diameters, the lead alloy, the shape of the hollow point and the base have, however, been adapted to the special requirements for using in air rifles. Diameter variants are .217 and .218, the weight options are 21, 23, 25, 27 and 30 grain. Count per box is 200.

We calculated the BCs as follows:



Please keep in mind that a BC is not a static value.

Who can shoot H&N Slug HP?

The H&N Slug HP will work fine in a broad variety of air guns but your gun should have at least 30ft/lbs of muzzle energy. So far I can definitely say that rifles from FX (like the Impact) with slugliner prefer the diameter .218, while the ones from Daystate (Red Wolf, Huntsman, Wolverine, etc.) and the Weihrauch HW 100/110 series shoot better with .217. All the above mentioned brands/models give excellent results at 110 yards (our standard testing range). If you are not sure about the best diameter and weight for your gun then you should try the H&N Slug Sampler.

Currently in development is the .25 and .30 H&N Slug HP. And we are also testing variants in shape (round nose and truncated cone) and material.

By the way: We have updated our logo. This will be found on the labels in the future.


 
Here is an update to our H&N Slugs HP:


1. Tests with the Vulcan and the KalibrGun Cricket were great. The Vulcan has a preference for .217 and the lighter weights (21 and 23 grain). Velocity is at 827 resp. 794 fps. The Cricket showed no clear preference in terms of diameter, but also loves the lighter H&N Slugs HP in 21 and 23 grain. Velocity is a little lower at 810 resp. 774 fps.


2. We are now developing the H&N Slugs HP for the caliber .25 and .30 in parallel. They should be ready for the market in February 2020. We also test alternative shapes and lead-free materials.
 
It's been a LONG wait since the announcement, but like they say - great things come to those that wait 😎

Just waiting for my orders for the heavier weights now, but these will be fun to test this weekend 👍

There were some challenges in the development of the Slugs HP that we had not expected upfront. But we wanted to make 100 % sure that we put a great product on the market. Add to that the long transport times across the Atlantic. 2 months door-to-door is not exceptional ... Now keep your fingers crossed that the .25 and .30 will be ready soon!
 
In a stock Impact with MKII plenum and 70cm slugliner my best performing slug for long range shooting is the 25 grain .217 H&N Slug HP @ 280mps / 918fps, with the regulator set just below 150 bar it shoots half MOA groups at 150 meter / 164 yard and it allows me to hit beer cans at 200 meter / 219 yard on a regular basis when I do my part.

Last week I've upgraded one of my two Impacts with the new FX Power Plenum kit but the transfer port and pellet probe were also enlarged by a friend with the proper tools and skills to use them. This allowed me to do a nice side by side comparison between the standard MKII and Power Plenum configurations with both the original and widened transfer ports.

For the best long range performance a minimum speed of 280mps / 918fps turned out to be essential, with the MKII plenum the 25 grain was the heaviest .22 slug I could (barely) shoot at that speed with the regulator set at 150 bar. With the Power Plenum installed and widened TP the combined average gain in speed is 40mps / 130fps however which pushes even the 30 grain to 300mps / 984fps at the same pressure so my attention will shift to the heavier slug for the higher BC.

Attached a graph of the results for the 25, 27 and 30 grain H&N Slug HP in .217, speeds were measured by a Labradar.
