.219 Zipper (Accurate Loading Guide #2)

The .219 Zipper is a rimmed wildcat cartridge derived from the .30-30 Winchester case, necked down to accept a .224-inch bullet. Accurate Loading Guide #2 includes updated load data that reflects modern powder performance, improved brass quality, and better bullet options compared to earlier manuals or factory loads. For handloaders interested in maximizing both accuracy and velocity, this guide offers relevant information for bullet weights in the mid-40 to early-50 grain range.

According to the information in Accurate Loading Guide #2 and related sources (such as Sierra’s legacy data), bullets of 46 to 55 grains perform well in the .219 Zipper when using medium-burn rate powders like IMR-4198, Accurate 2230, IMR-3031, IMR-4895, and similar. These powders help fill the case adequately while maintaining safe pressures and clean ignition, resulting in flatter trajectories and more consistent shot groups.

Sierra’s legacy data shows that when using a 26-inch barrel with a 1-in-14” twist, a 45-grain bullet over Accurate 2230 or IMR-4895 can reach velocities in the low 3,000 fps range. The manual cautions that case forming (neck turning or reaming) is necessary when converting from parent cases due to neck thickness issues, and consistent case trim length and bullet seating depth play key roles in maintaining accuracy. This is in line with what Accurate Loading Guide #2 prescribes: careful component selection and load tuning rather than just using “maximum” data.

Accuracy results cited include tight groupings at 100 yards, especially when using high-quality bullet profiles (such as Hornady flat nose or Sierra spitzers), consistent brass prep, and minimal bullet jump to lands. Medium charge loads provide a balance of velocity, barrel life, and heat management. Users of Guide #2 also note that recoil remains manageable and that barrel life is considerably better when staying away from aggressive loads.

For shooters using rifles with standard twist rates and well-finished chambers, the .219 Zipper with loads from Accurate Loading Guide #2 offers a reliable and somewhat under-utilized cartridge choice. It bridges the gap between vintage varmint classics and modern small-caliber performance, especially in rigs where ballistic coefficient, bullet construction, and load consistency are valued.
