Hornady A22250 Lock-N-Load Modified Case - 22-250 Rem Rifle Brass

The Hornady A22250 Lock-N-Load Modified Case is a precision reloading accessory engineered specifically for 22-250 Remington ammunition. If you're serious about handloading and want to dial in your cartridge overall length (OAL) with benchrest-grade accuracy, this modified case lets you use Hornady's Lock-N-Load Precision gauges to achieve measurements consistent to .001". It's the foundation of repeatable, tight-tolerance ammunition—especially valuable for long-range hunting and precision rifle work where every tenth of a grain and hundredth of an inch compounds downrange.

The case features a fine-pitch threaded case-head that attaches securely to the Lock-N-Load gauge and holds perfectly square for proper chamber alignment. The neck is precisely opened and rounded to a .002" oversized diameter, allowing your exact loading bullets to seat concentrically without binding or misalignment. This concentricity matters: it reduces runout, improves consistency shot to shot, and helps you get the most from your precision rifle. The case itself is held to SAAMI specifications, so dimensions and tolerances are standardized.

Use the same bullet diameter you intend to load in your ammunition; the slightly oversized neck accepts them effortlessly while maintaining that critical concentricity. This interchangeable modified case works with either Hornady O.A.L. gauge model. It's a single case for testing and developing loads—not a full box for production, but an essential tool if you reload 22-250 and want to eliminate guesswork from your OAL setup.

Frequently Asked Questions

What gauges does the Hornady A22250 modified case work with?

The case has a threaded case-head compatible with both Hornady Lock-N-Load O.A.L. gauge models. The gauge itself is sold separately.

Can I use this modified case to measure my actual loading bullets?

Yes. The .002" oversized neck accepts your exact-diameter loading bullets concentrically, so you can dial in the true OAL for your chosen projectile and set your seating die accordingly.

Is this a full box of brass for reloading ammunition?

No. This is a single modified case designed for use as a precision measuring tool with the Lock-N-Load gauge. It allows you to establish accurate OAL dimensions before full-scale handloading.

How does the .002" oversized neck improve accuracy?

The slight oversizing allows bullets to seat concentrically (centered) in the case mouth without binding or tilting. Concentric seating reduces runout, which improves consistency and helps tighten shot groups, especially important for long-range and precision rifle applications.
