Polish Inside of Seating Stems to Avoid Ring Marks on Bullets

Seating Stem Reloading Tip Sierra Bullet .223 Remington compressed loads

Here’s a helpful hint for hand-loaders from Sierra Bullets. While this article focuses on Sierra’s new Tipped Match-King bullets, the recommended solutions apply to other bullet types as well. The article explains how sharp edges on a seating stem can cause a ring to be pressed into the bullet jacket — especially with compressed loads that resist downward bullet movement. Here Sierra technician Rich Machholz diagnoses the problem and provides a solution.

Solutions for Ring Marks Caused by Seating Stems

by Sierra Bullets Ballistic Technician Rich Machholz
Now that the new Tipped MatchKing® (TMK) bullets are being shipped and shooters are putting them to use I have received several calls regarding marking on the bullet ogive from the seating stem.

The cause can be traced to one of several things. In the .223 and especially with the long, 77 grain TMK seated at 2.250” or even 2.260” most loads of Varget® and Reloder® 15 are compressed loads, sometimes heavily compressed. This puts a great deal of pressure on the bullet through the seating stem. The result of all this pressure is a mark of varying depth and appearance on the ogive of the bullet. [Editor: We have seen this issue with a variety of other bullet types/shapes as well, including non-tipped VLDs. The solution is profiling the internal cone of the seating stem to match your bullet shape.]

Some older seating stems might even bear against the tip of the bullet which can make a slight bulge in the jacket just below the junction of the resin tip and the copper jacket in a compressed load. If this is the case there is not a ready fix other than calling the die manufacturer and requesting a new deeper seating stem.

Polish Your Seating Stem to Remove Sharp Internal Edges
If the seating stem is of proper depth the culprit most generally is a thin sharp edge on the inside taper of the seating stem. This is an easy fix that can be accomplished by chucking a spare 77 grain bullet in your drill, coating it with valve grinding compound or even rubbing compound or in a pinch even tooth paste.* Remove the seating stem assembly from the seating die. Turn the drill on and put the seating stem recess over the spinning bullet with the polishing compound to break or smooth the sharp edge that is making the offending mark. This might take more than one application to get the proper polish depending upon what you use, but the more you polish the better the blend of angles which will [ensure the stem matches the bullet contours, not leaving a sharp ring].

If the above is a little more than you care to tackle you might try very fine emery cloth twisted to a point that can be inserted into the mouth to the seating stem and rotated to polish the inside to eliminate any sharp edges that might be present.

Load Advice for 77gr TMKs in the .223 Rem
And last but certainly not least. Actually, even though we don’t say you need additional data for the TMKs, remember you are dealing with heavily-compressed loads in some cases because of the additional bullet length. Due to the additional length of these new bullets and in the interest of gaining some room in the case you might consider trying a slightly faster extruded powder like BenchMark or the 4895s or an even more dense powder like the spherical H335®, CFE223 or TAC. The extra room will allow for trouble free bullet seating also.

Good luck and remember we are no further away than your telephone: 1-800-223-8799.

Rimfire Reactives — Spinners, Dueling Trees, Plate Racks & More

rimfire reactive steel target spinner dueling tree falling plates Volquartsen
An accurate, self-loading .22 LR rifle, such as this Volquartsen, is our gun of choice for speed shooting with rimfire reactive targets.

Reactive targets offer “instant gratification” — with every hit your target moves, spins, or falls. Shooting reactive targets with a rimfire rifle is fun AND affordable. Times are a-changin’ — rimfire ammo prices have dropped dramatically, so you can now get very good rimfire ammunition for just four bucks a box, such as Norma Tac-22. That works out to a mere eight cents a round. At that price, you can afford to shoot every weekend.

Rimfire Biathlon Target — Tons of Fun
RimfireSteel.com offers the unique Rimfire Steel Biathlon Target, a scaled-down Biathlon target designed for use at 50 feet for training and recreational shooting. This is one of our favorite rimfire targets. You can increase the level of challenge by moving it to 25 yards! Watch the video — it shows how to reset the five plates remotely with a lanyard.

Make Your Own Shooting Gallery with Reactive Rimfire Targets
For .22 LR fans, the folks at Action Target have created a whole series of steel rimfire targets. Much lighter than their centerfire counterparts, these rimfire targets are easier to transport and easier to set up. With this wide selection of reactive targets, you can create your own shooting gallery.

In this video, Michael Bane reviews Action Target’s line of rimfire targets, which includes plate racks, spinners, dueling trees, and more. As Michael explains: “This line of targets is very well thought out. For example — dueling trees are a lot of fun. But a centerfire dueling tree weighs a lot, it’s hard to cart it around. A rimfire dueling tree is easy to set up, easy to carry around.”

New PT Target “Walks” When Hit
Action Target has just released a new reactive target that doesn’t even need a stand or base. The patent-pending PT Twist rests on the ground, and flops over or “walks” when hit. Constructed from a single piece of 3/16″-thick A514B steel, the PT Twist has no welds or bolts to break or ricochet. Watch the PT Twist in action:

Daisy Will Support Boy Scouts’ Marksmanship Training

Daisy Boy Scouts America BSA portable inflatable BB Gun Range

“Involvement in the shooting sports develops … discipline, patience, self-control, and responsibility.” — Daisy President, Keith Higginbotham

Like many of our readers, your Editor got his first introduction to organized shooting sports through the Boy Scouts. At a Scouting summer camp I participated in competitive target shooting with both airguns and single-shot .22 LR rifles. That experience helped me earn my Rifle Shooting Merit Badge. That marksmanship badge remains one of the most popular non-mandatory Merit Badges. Since 2009, over 350,000 Rifle Shooting Merit Badges have been earned by young scouts.

Given the vital role Scouting plays in developing the next generation of shooters, we’re pleased that Daisy has agreed to partner with the Boy Scouts of America (BSA). This agreement makes Daisy the official airgun of the Boy Scouts of America.

This partnership makes Daisy’s unique inflatable BB Gun ranges available to the BSA’s 274 local councils as well as BSA camp sites across the country. Instructors emphasize shooting safety rules and teach basic marksmanship, including breath control, trigger pull, sight picture and more.

Daisy President Keith Higginbotham stated: “Teaching the basics of marksmanship and shooting safety… continues to be at the core of our mission. Hundreds of millions of adults have been positively affected by Scouting, learning to become responsible citizens, developing character and becoming self-reliant. Involvement in the shooting sports develops similar traits, such as discipline, patience, self-control, and responsibility.”

Daisy Inflatable BB Gun Range
Daisy’s unique inflatable BB Gun Ranges can be deployed at Scout camps, and as well as hunting and conservation events. These mobile ranges allow instructors to teach young poeple gun safety rules and marksmanship skills. When set-up, the range measures 22′ 5″ long by 9′ 6″ wide by 8′ 6″ tall.
