Smith & Wesson Revives Model 648 .22 WMR Revolver

We love Smith & Wesson rimfire revolvers. We have put thousands of rounds through S&W Model 617 revolvers, with 4″ and 6″ barrels. These stainless .22 LR handguns are accurate, superbly reliable, and they hold their value. In general we’ve found that Smith & Wesson rimfire revolvers may be less fussy with ammo, and more trouble-free than typical semi-auto rimfires. Bottom line, we feel that everyone should have an S&W rimfire wheelgun in their collection.

And now there’s a great additional Rimfire Revolver option from Smith & Wesson — the “revived” Model 648 in .22 WMR. This stainless Model 648 brings a more powerful cartridge to S&W rimfire revolver fans.

smith wesson S&W model 648 revolver wheelgun .22 WMR Winchester magnum rimfire 6Built on S&W’s medium K-frame, the 8-round Model 648 is designed for small game hunting and target shooting. The .22 WMR is definitely a much more potent varmint cartridge than the .22 LR. You have more downrange energy plus a flatter trajectory. While the 648 does not come with an integral scope rail, it is not difficult to mount red dot or optical sights to this wheelgun.

The Model 648 revolver is built on a stainless steel medium K-frame and includes black synthetic finger groove grips, a black patridge front sight, and adjustable rear sight. This impressive revolver features a full underlug six-inch barrel, eight-round capacity, and is available with an MSRP of $749.

Model 648 History and Features

According to Guns.com: “The K-frame .22 WMR-caliber Model 648 first appeared in Big Blue’s lineup in 1989 sporting a full-lug barrel and stainless steel construction. Retired since 2005, the newest generation of the Model still brings a 6-inch barrel to the party, which translates to a very commanding 11.1-inch overall length. Weight is 46.2-ounces in the eight-shot .22 Mag, making the gun attractive for both those looking to fill pots and smoke targets.” Shown below is a vintage Model 648.

Jan Mladek, General Manager of Smith & Wesson General Manager Jan Mladek reports: “The Model 648 is back in production to satisfy the needs of handgun owners who are looking to achieve greater distance while hunting or target shooting. With a full underlug, six-inch barrel and a patridge front sight, the Model 648 has been designed … to boost accuracy at longer distances. While we currently offer .22 Magnum revolvers in both our J-frame and Classics line, we are excited to add this new .22 Magnum revolver to the modern K-frame lineup.”

Bullet Tip Touches Comparator Body Before Ogive Reaches Insert

Bullet ogive comparator gauge tool drill fix hybrid ogive bullet

Bullet ogive comparator gauge tool drill fix hybrid ogive bulletDo you shoot long, pointy Hybrid Ogive bullets? If so, you may need to modify the Hornady L-N-L Bullet Comparator tool commonly used to measure the distance from bullet base to bullet ogive.

With modern, high-BC match bullets, so much of the bullet may extend forward of the ogive that the bullet tip actually contacts the inside of the red comparator body BEFORE the bullet’s ogive contacts the gray caliber-specific insert ring attached to the red body. When this happens you will NOT get an accurate Base-to-Ogive (BTO) measure. And likewise you will not get a proper Cartridge-Base-to-Ogive (CBTO) measurement with loaded rounds.

Watch this video — it shows exactly how this measurement “fail” can happen with a .338-caliber Berger Elite hunter bullet. The tester was getting a false bullet Base-to-Ogive reading of 1.175 (0:25 timemark) before modifying his tool. The true BTO measurement, with the bullet actually contacting the gray comparator ring, is 1.121 (1:25 timemark):

How to Fix the Problem
What’s the fix? With a drill, you must relieve the back “wall” inside the red comparator holder bore. This will provide more clearance for the bullet tip. With more clearance the bullet ogive will seat properly on the gray, caliber-specific insert. The tip will no longer bottom out on the red clamping half of the tool.

The maker of this helpful video, EuLRH explains: “As we all know the CBTO (Cartridge Base to Ogive) measurement is [more useful than] COAL (Cartridge Overall Length). There are lots of products that can do this. One of them is Hornady L-N-L bullet comparator. Attention! With modern long range bullets it is possible that the bullet tip is touching the comparator body instead of the bullet ogive touching the gauge.” In this example, EuLRH worked with the 300gr Berger elite hunter bullet in .338 Caliber.

Why You Need to Check with Your Own Loads
If your bullets have this “tip touching” issue, when you measure your loaded rounds you will be seeing COAL instead of the Cartridge Base to Ogive (CBTO) length. Take a moment, test with your own bullets and your comparator to determine if you have this measurement problem. If you do, try the drilling solution shown in the video.

(aka Nodak7mm) has compiled a useful list of 112 ranges throughout the USA where F-Class matches are held. With venues from Alabama to Wyoming — you should find an F-Class program not too far from home. The list, in Excel spreadsheet format, provides range locations and weblinks (where available). Click the link below to download the F-Class Range List (.xls file):
