Basics of Bullet Seating Lengths — Jump vs. Jam

Many folks getting started in the cartridge reloading game are not fully familiar with seating depth options. They may only be looking to achieve a listed Overall Length (OAL) from base to bullet tip. But, for optimal accuracy and safe functionality, you need to look at the position of the bullet’s ogive relative to the start of the barrel’s rifling (i.e. the point where bullet jacket contacts the barrel rifling). Before you start reloading you want to measure the distance to the lands. Then, for most applications you want to start with the ogive’s contact point at least .010″ or more back away from the lands — that is called “jumping”.

For some benchrest applications you may want to actually have the bullets seated longer so the bullet actually contacts the lands. That is called “jam” seating. But there are variations in that. There is both a “mild” jam — a few thousands into the lands — as well as a full jam where the bullet is seated very long (and may even push back if case neck tension is light). Be very cautious with a full jam as this can significantly increase case pressure.

How to Improve Accuracy

In this video, F-Class John explains some key techniques on optimizing match ammo. He explains how to get very precise powder loads. In the video he respond to multiple questions from his Patreon subscribers. One topic is how to avoid the outliers in a 10-shot group. If those “flyers” are consistently coming at the end of a long string, John explains the problem is not likely the ammunition. Rather it could be a variety of factors such as “driver fatigue”, wind changes, barrel heating or other issues. For competitive shooters, this video is worth watching start to finish.

Patriotic July 4 Accuracy Target

The USA’s 250th birthday is behind us, having been celebrated on July 4, 2026. In this video F-Class John shows a fun 5-star red, white, and blue patriotic target and explains some of the challenges in getting an optimal score. There is a black bull inside the center star. Another feature of this target is that you can use the points on the stars to precisely aim your cross-hairs. This is a good target for centerfire at 100 yards, rimfire at 50 yards, and handguns at closer ranges.

Rear Bag Filling — Tips for Best Results

In benchrest and F-Class disciplines, you need a good rear bag to optimize accuracy and scores. A quality rear bag both supports and stabilizes the rifle and helps the rifle track properly during recoil. To get the best, most consistent performance from rear bags, you need to optimize the fill. In this video F-Class John discusses fill options and shows the process to fill your rear bag properly. He also talks about notable bag features including bag weight, footprint, and ear height/material.

Budget-Priced Arken EPL-4 Scope That Performs Well

Top competitors may spend $2500 or more on a top-quality, high-magnification rifle scope. But for those on a tighter budget, the Arken EPL-4 offers pretty impressive performance for under $350.00. In this video John tests this optic from the bench and shows that it has good glass and functions well. The EPL-4 combines Japanese ED glass with illuminated VPR or VHR FFP reticles. The Arken EPL-4 is offered in two sizes: 4-16x44mm ($299.99 at MidwayUSA) and 6-24x50mm ($329.99 at MidwayUSA).

Advanced AMP Press for Precision Bullet Seating

The AMP Electronic Bullet Seating Press is a state-of-the-art bullet seating press that tracks seating force round by round. The AMP Press combines a motor driven ram, a distance sensor, and a load cell to deliver extremely accurate and precise bullet seating measurements. It is designed for use with inline bullet seating dies. With this press you can quickly and easily change seating depths, which is useful during load development. In addition, the AMP press outputs data from the seating process to a linked computer. This allows you to see if there is an unusual seating value. You can mark those “outlyer” rounds and use them for fouling or warm-up shots.
