Mr. Michael Fifer, President and CEO of Sturm, Ruger:

Since you have requested input from Ruger customers via the "Tell the CEO" program, I thought that I would respond with an article about a subject that I have long found perplexing--the quixotic availability of different cartridges in different rifle models. Sometimes the Company's cartridge offerings seem to have been made almost without consideration of the cartridge's requirements in terms of ballistics and barrel length, rifle weight to tame recoil, or even the anticipated purpose to which a given model of rifle will presumably be used. Thus, I would like to start by suggesting the following general guidelines.

1. Offer cartridges in rifles of sufficient weight (when equipped with a telescopic sight and mount weighing one pound) to keep recoil energy below 15 ft. lbs. with typical factory loads whenever possible and below 20 ft. lbs. at the most. I realize that for the most powerful cartridges (generally .300 Magnum and above) this is often not possible, but at least these cartridges should be restricted to the heaviest available rifles.

2. Barrel length for short and medium range cartridges that offer a maximum point blank range out to around 200 yards should be no shorter than 20" to retain some semblance of ballistic efficiency. Barrels for high intensity cartridges (.243, .270, .308, .30-06, etc.) should normally be 24" in length and not shorter than 22". The 6.5mm Rem. Mag., .350 Rem. Mag and RCM cartridges should get at least 22" barrels. Other magnum cartridges, belted, short or otherwise, should not be offered in barrels shorter than 24". You can read more about barrel length and velocity loss in the article "Rifle Barrels," which can be found on the Rifle Information page.

Now for some specific cartridge suggestions for the individual models of Ruger hunting rifles included in the Ruger 2009 Catalog. I will restrict my suggestions to cartridges for which Ruger chambers in 2009 or has in the past. In other words, cartridges for which Ruger can chamber without a large additional investment.

MINI-14 AUTOLOADING RIFLES

Mini-14 (all models): .223 Rem., 6.8mm SPC

In closing, you will notice that I have dropped the big bore revolver cartridges from the No. 1-S Medium Sporter and substituted rifle cartridges. It is, unlike a revolver, capable of chambering physically longer and far more effective cartridges than any revolver. A rifle weighs more and is longer and heavier than a revolver, so if a hunter is willing to commit to carrying a rifle, it only makes sense to take advantage of the long gun's capabilities. (Conversely, it makes no sense to carry a big game hunting rifle chambered for cartridges that are commonly available in far lighter and handier revolvers.)

In addition, I have suggested international cartridges for use in the International version of the No. 1. In any case, its barrel is too short for efficient use of long range cartridges such as the .243 Win. and .270 Win.
