You bought an RCBS press because it is reliable, but now you are seeing a headstamp shift, a rattle, or a die that refuses to seat properly. This page separates real mechanical faults from user error and tells you exactly which part to adjust or replace.
In short: Most RCBS press complaints stem from loose bench screws, worn bushings, or using the wrong die for the frame. The Rock Chucker and Summit are generally robust, but the Rebel's die adapter can be tricky if not seated correctly. Fixing these issues usually requires tightening the base, checking for burrs, or swapping to a compatible die set.

Hornady Custom Grade dies have tighter tolerances that eliminate the rattle many RCBS users complain about.
The .300 Blackout taper crimp die fixes seating issues that generic RCBS die sets often miss on semi-auto brass.
The Wobble Problem: Why Your RCBS Press Is Not Straight
Wobble is the #1 complaint for RCBS Rock Chucker and Summit users. It usually means the press base is not fully tightened to the bench or the case ram spring is fatigued. The other half of this decision is rcbs press stand.
If the press moves laterally, your headstamps will shift, making brass inconsistent. This is not a defect in the casting; it is an installation error.
- Check the bench screws: RCBS bases have four points of contact. All must be tight.
- Inspect the ram: Lift the handle and spin the ram. If it feels loose, the bushings inside the frame are worn.
Pro tip: Never run the press with the handle at full top if the case is empty. This stresses the internal linkage and can accelerate bushing wear.
A dedicated mounting kit ensures the base is anchored to the bench without crushing the surface, eliminating lateral play.

Rebel Press Die Adapter: The Most Common Setup Mistake
The RCBS Rebel is a turret-style press, and its die adapter is the source of most complaints. Users report that dies do not seat evenly or that the turret clicks are not smooth.
This is because the Rebel requires a specific die length. If your dies are too short, they do not grip the adapter fully. If they are too long, they hit the frame.
- Measure your die length against the RCBS spec for the Rebel.
- Ensure the adapter is fully screwed down before tightening the top lock.
- Use a spacer if your dies are short, rather than forcing the handle.
Safety first: If the turret skips a station, do not force it. This can shear the detent pins and ruin the mechanism.
The .300 Blackout die set is designed with specific length tolerances that fit the Rebel's adapter without needing shims.

Die Fit and Consistency: Solving the 'Scratching' Complaint
Many RCBS owners switch brands because they feel the included die bodies have rough internal surfaces that scratch case heads or jam bullets. Before you buy anything, it is worth looking at selecting your first reloading tool.
This is often a case handling issue, but sometimes it is a die flaw. Cheap die sets, regardless of brand, can have burrs at the die opening.
If you are seeing case necks getting thinner or bullets deforming, the issue is likely not the press but the die quality.
- Deburr your dies: Use a fine file or needle on the top of the die body before your first test round.
- Upgrade the dies: Premium die sets have honed spindles and smoother chambers.
Pro tip: Always lubricate case necks even if the die is new. Friction from unlubed brass is the most common cause of die sticking.
Hornady Custom Grade dies are honed and polished, removing the surface roughness that causes the scratching complaints common with entry-level RCBS sets.

Rock Chucker vs. Summit: Which Press Should You Actually Buy?
The Rock Chucker Supreme is the workhorse. The Summit is the pro-grade option. The difference is in the frame casting and the bushing quality.
If you are reloading high-volume handgun ammo, the Rock Chucker is sufficient. The complaints about it usually stem from user technique, not the metal.
If you are reloading precision rifle ammo, the Summit’s heavier frame reduces harmonic vibration. This translates to tighter groups on the bench. For competition shooters, the Summit is the better investment to stop chasing mechanical error. There is more on lyman turret reloading platforms in a separate guide.
How to Set Up Your RCBS Press for Zero Complaints
Most ‘defective’ RCBS presses are actually just poorly set up. The process is straightforward if you follow the manufacturer’s tolerance specs.
Start by ensuring the press is centered on the bench. The handle should be parallel to the die adapter when at the top of the stroke. Use a straightedge to check alignment.
Then, back the die down until you just touch the die. Add 0.010 inches of clearance. This prevents the die from riding on the case and causes the ‘sticking’ complaint.
When to Call It a True Defect
If the frame is cracked, the handle mechanism is grinding metal-on-metal, or the turret pins are bent, that is a defect. These are rare.
RCBS has a lifetime warranty on their frames for most models. If you are hearing a grinding noise from the internal linkage, stop using the press and contact RCBS support.
Do not attempt to repair internal bushings yourself. They are pressed into the casting and require specialized tooling to replace correctly.
The bottom line
Most RCBS press complaints are solvable with better bench mounting and higher-quality dies. If you are struggling with wobble or sticking, upgrade your die set to a honed brand and ensure your press base is fully tightened. For precision work, invest in a Summit frame; for everyday use, the Rock Chucker is fine if you follow the setup specs.

Frequently asked questions
Is the RCBS Rebel press a good choice for rifle reloading?
The Rebel is a single-stage turret press. It is excellent for reloading rifle cartridges because it allows you to hold the turret in place while you change dies. It is more efficient than a single-stage press but less fast than a progressive. If you want speed, a progressive is better. If you want simplicity, the Rebel is a strong choice.
Why does my RCBS Rock Chucker make a rattling noise?
Rattling usually indicates a loose die or a worn bushing. Check that the die is hand-tightened enough to sit on the base of the frame. If the noise persists, the internal bushings in the frame may be worn, allowing the ram to move laterally. This is a wear item that eventually requires a new frame.
Can I use Hornady dies in an RCBS press?
Yes, as long as the die body length is compatible with the press’s adapter. Most standard die bodies fit both RCBS and Hornady turrets, but you must check the adapter depth. If the die is too short, it will wobble. If it is too long, it will not seat. Use a spacer if needed.
