Along with .22 LR, the LA101 is offered in .22 WMR and 17 HMR chamberings.

There’s an impressive bolt-action rimfire rifle built in Australia, the LA101 Crossover from Lithgow Arms. Imported by Legacy Sports Int’l, this relatively new rimfire rifle offers a smooth-running action, excellent accuracy, a crisp trigger, and a durable, Cerakote finish.

YouTube host 22Plinkster recently tested the LA101 in .22 LR, and found that it delivered very impressive accuracy. He recorded multiple “one-ragged-hole” groups at 50 yards (see video below). Even at 100 yards, the LA101 was shooting close to 1 MOA with relatively inexpensive ammo. This is an impressive rifle, as it should be, with a $1000+ price tag. MSRP is $1079.00 USD (synthetic), $1215.00 USD (laminate).

22Plinkster writes: “I have shot a lot of .22 LR bolt rifles in my day, but this one, is a nail driver!” After testing, he concluded that the LA101 was “the most accurate bolt rifle I own”. He reports the stock is very comfortable for off-hand shooting as well as bench work.

LA101 Crossover Features and Specifications
The Lithgow Arms LA101 Crossover features a 3-lug, 60°-throw action with rear-locking bolt. It is available in both right-hand and left-hand versions, with a very good factory trigger advertised at 3.3 pounds (1.5 kg). Note — testers report report the trigger feels lighter. Choose between a fiberglass-reinforced polymer stock, Walnut, or laminated wood stocks. This rifle is offered in three rimfire chamberings: .22 LR, .22 WMR, and 17 HMR. The .22-cal barrels are hammer-forged while the 17 HMR barrel is button-broached. Action and barrels are Cerakote finished. The Lithgow LA101 can use CZ 452/455 5-round and 10-round magazines.

Here is another, lengthy LA101 review, done in Australia a couple years back. The reviewer field-tests a composite-stocked Lithgow LA101 with a wide variety of .22 LR ammunition. Warning: Starts with loud, annoying music — you may want to turn down your speakers:

Tech Tip: Figuring Out Barrel Twist Rates

Sometimes you’ll get a barrel that doesn’t stabilize bullets the way you’d anticipate, based on the stated (or presumed) twist rate. A barrel might have 1:10″ stamped on the side but it is, in truth, a 1:10.5″ twist or even a 1:9.5″. Cut-rifled barrels, such as Kriegers and Bartleins, normally hold very true to the specified twist rate. With buttoned barrels, due to the nature of the rifling process, there’s a greater chance of a small variation in twist rate. And yes, factory barrels can be slightly out of spec as well.

After buying a new barrel, you should determine the true twist rate BEFORE you start load development. You don’t want to invest in a large supply of expensive bullets only to find that that won’t stabilize because your “8 twist” barrel is really a 1:8.5″. Sinclair International provides a simple procedure for determining the actual twist rate of your barrel.

Sinclair’s Simple Twist Rate Measurement Method
If are unsure of the twist rate of the barrel, you can measure it yourself in a couple of minutes. You need a good cleaning rod with a rotating handle and a jag with a fairly tight fitting patch. Utilize a rod guide if you are accessing the barrel through the breech or a muzzle guide if you are going to come in from the muzzle end. Make sure the rod rotates freely in the handle under load. Start the patch into the barrel for a few inches and then stop. Put a piece of tape at the back of the rod by the handle (like a flag) or mark the rod in some way. Measure how much of the rod is still protruding from the rod guide. You can either measure from the rod guide or muzzle guide back to the flag or to a spot on the handle. Next, continue to push the rod in until the mark or tape flag has made one complete revolution. Re-measure the amount of rod that is left sticking out of the barrel. Use the same reference marks as you did on the first measurement. Next, subtract this measurement from the first measurement. This number is the twist rate. For example, if the rod has 24 inches remaining at the start and 16 inches remain after making one revolution, you have 8 inches of travel, thus a 1:8 twist barrel.

Determining Barrel Twist Rate Empirically
Twist rate is defined as the distance in inches of barrel that the rifling takes to make one complete revolution. An example would be a 1:10″ twist rate. A 1:10″ barrel has rifling that makes one complete revolution in 10 inches of barrel length. Rifle manufacturers usually publish twist rates for their standard rifle offerings and custom barrels are always ordered by caliber, contour, and twist rate. If you are having a custom barrel chambered you can ask the gunsmith to mark the barrel with the twist rate.
