Does Internal Case Volume Affect Ballistic Performance?

Aserious rifle benchrest shooter will go through a course of fire with a single case, reloading it on the firing line. The objective is to assure repeatable accuracy in a load carefully worked up to shoot groups measured in thousandths of an inch. Among the things the shooter eliminates by repeatedly using the same brass is the deviation in ballistics caused by internal case volume (ICV).

Even when a box of brass comes from the same lot and manufacturer, there's no way to be certain of their individual ICV without taking measurements. The identical powder charge, bullet and primer in a case with an ICV of 0.66, for example, will produce a different ballistic profile than in a case with a...

Bad Guns, Bad Guns: What You Gonna Do When They Fail on You?

Throw-down gun, Saturday night special, gat, heater, rod. These nicknames stick to cheap, widely available handguns because they show up in police reports and tabloids more often than they do in the results of organized shooting matches. But are such guns produced with evil intent, or are they instead inexpensive firearms which help those on the lower end of the economic spectrum defend themselves? Are these low-priced guns so "bad" that foes of gun control have a legitimate product-safety argument to deny lower-income citizens the right to bear arms based merely on cost and availability?

To assess the merits of this question, Gun Tests recently acquired and fired a trio of handguns and 3...

GTs 1999 Guns of the Year: Your Cant-Miss Firearms Buys

The year of 1999 saw a great deal of innovation in all areas of fireams development, including the use of a high-tech metal (titanium) in revolvers, the broadening use of plastic (also called polymer) in semiauto handguns and shotguns, and the codification of benchrest manufacturing techniques in rifles (including aluminum bedding blocks in riflestocks). As we tracked these trends and tested products in the critical head-to-head format found only in Gun Tests, we gave you our best advice on what guns we thought deserved your money in their respective classes. When we get to the end of the year, we're able to look back over the previous 12 months and see what guns broke the mold in terms of p...

Powerhouse Lever Rifles: We Like The Guide Gun

Handy rifles seem to find their ways into the hearts of outdoorsmen all over the world, whether they're in Alaska or Africa or deep in the heart of Texas. Handy can mean many things, but most of all it implies ease of carrying, combined with adequate power for whatever use to which it might be put. We'll wager the average reader seldom thinks of a lever-action rifle, except the .30-30, when handy rifles are mentioned. Most riflemen of our acquaintance think in terms of short-barreled bolt rifles of "handy" calibers, like a Ruger Model 77 carbine in .308, or a custom 7x57, or perhaps the little Mannlicher-Schoenauer carbine in 6.5x54.

We certainly never thought about a .45-70—in any config...

.308 Bolt-Action Showdown: Weatherby Beats Sako, Browning

[IMGCAP(1)] Some time back (April 1998) we tested a Sako Model 75 Hunter in .308, when it won a head-to-head hunting-rifle competition against a Browning A-Bolt II Eclipse and a Steyr SBS Forester. As such it garnered a hard-earned Buy recommendation, and in our view, it has been one of the strongest performers in its category—a king of the hill, if you will.

Thus, we wondered how that gun's performance would hold up against new challengers, such as a $999 Weatherby Mark V and a $636 Browning A-Bolt II Medallion. At the time of that earlier test, the .308 Sako retailed for $1,055, but in the intervening years, new Sakos have gone up in price to $1,185. Since the Sakos are basically unchan...

Big-Bore Lever-Action Hunting Guns: Pass On Marlins New .450
