This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.90.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 10:02, 6 April 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''.17 Hornet''' is a .17 caliber [[centerfire]] [[rifle]] [[Cartridge (firearms)|cartridge]] originally offered as a "wildcat cartridge" developed by [[P.O. Ackley]] in the early 1950s. He created this non-factory (wildcat) offering by simply necking-down the [[.22 Hornet]] to .17 caliber and fire-forming the resized cases in his new chamber design. The result was a small quiet cartridge capable of high velocity. Ackley mentions it as one of the most balanced of the .17 cartridges of his time; likely, this is still true.<ref>Cartridges of the World 8th Edition, Book by Frank C. Barnes, DBI Books, 1997, ((ISBN|0-87349-178-5))</ref>

Sixty years later, the [[Hornady|Hornady Manufacturing Company]] ([[Grand Island, Nebraska]], [[US]]) turned Ackley's idea into a commercial product with a similar cartridge; the .17 Hornady Hornet uses a 20 grain (1.3 gram) "Superformance" V-max projectile with a published velocity of 3,650fps (1,113 metres/second).
<ref>((cite web|url=http://www.hornady.com/store/17-hornet-20-gr-V-MAX-Superformance|title=17 Hornet 20 gr V-MAX Superformance Varmint|accessdate=29 August 2012|archive-url=https://web.archive.org/web/20131226163111/http://www.hornady.com/store/17-hornet-20-gr-V-MAX-Superformance|archive-date=2013-12-26|url-status=dead))</ref>

However, the new standardized ammunition and brass is not built to exactly the same dimensional specifications as the original wildcat or the dimensions listed on this page. Hornady's standard has a shorter body with less taper and shorter overall case length while the overall loaded length remains 
that of the original .22 Hornet (in order to fit the standard Hornet magazines). Shooters using the .17 Hornady Hornet in a .17 Ackley Hornet chamber experience the bullet jumping to the rifling and losing some of the inherent accuracy for which the cartridge has been known.

It has been reported the .17 Hornady Hornet uses a thicker rim than the original Hornet case.  However, the ninth edition of the Hornady ''Handbook of Cartridge Reloading'' shows them to be the same (.065 inches); measuring the rims of actual factory cases shows the Hornady handbook to be correct. Moreover, Ackley's ''Pocket Manual for Shooters and Reloaders'' shows the rim thickness for his wildcat to range between .069" and .063" which is consistent with the Hornady handbook.  Both cartridges head-space on this rim.

While the Ackley cartridge uses a 30-degree shoulder angle and the Hornady is 25 degrees, its longer shoulder is accommodated by Ackley's longer case body. Fireforming moves the Hornady's shoulder forward at the expense of neck length. 

There is another size issue: according to Ackley's manual, his wildcat cartridge is only .289" over the shoulder while the Hornady factory round measures .294". This is the reason the Hornady's case capacity is almost identical to that of the Ackley's. Since there is five-thousandths less taper in the case body, the new .17 Hornady Hornet cases may not fit an Ackley chamber without full-length resizing.

Existing rifles chambered for the Ackley wildcat can have their barrels set back one turn and rechambered to the new .17 Hornady Hornet which meets the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) standard for the .17 Hornet. This fixes the bullet jump issue and improves ammunition availability with little risk of diminished performance.
