Explore the pros and cons of rimfire bull barrels to make an informed choice whether they are a good upgrade for your shooting needs.

In the world of rimfire rifles, enthusiasts are always looking for ways to enhance accuracy and performance. One popular modification that has gained traction in recent years is the use of bull barrels. Rimfire bull barrels have become a topic of much discussion among shooters, with proponents praising their benefits and skeptics questioning their necessity. This article will explore the advantages and disadvantages of bull barrels for rimfire rifles, helping you make an informed decision about whether this modification is right for your shooting needs.

Before diving into the pros and cons, it’s essential to understand what rimfire bull barrels are. A bull barrel is a thicker, heavier barrel compared to standard rifle barrels. When applied to rimfire rifles, these bull barrels maintain a consistent diameter along their entire length, rather than tapering towards the muzzle like traditional barrels. Rimfire bull barrels are designed to improve accuracy and reduce barrel vibration during firing.

Pros of Rimfire Bull Barrels

Enhanced Accuracy

One of the primary advantages of rimfire bull barrels is their potential to improve accuracy. The increased mass and rigidity of bull barrels help to minimize barrel vibration and harmonics during firing. This reduction in movement translates to more consistent shot placement, especially when firing multiple rounds in quick succession. Many shooters report tighter groupings and improved long-range accuracy after switching to rimfire bull barrels.

Better Heat Dissipation

Bull barrels have a larger surface area, which allows for more efficient heat dissipation. This is particularly beneficial during extended shooting sessions or in competitive environments where numerous rounds are fired in a short period. The improved heat management of rimfire bull barrels helps maintain consistency in shot placement even as the barrel heats up, reducing the impact of thermal expansion on accuracy.

Increased Stability

Rimfire bull barrels add weight to the front of the rifle, which can improve overall balance and stability. This added stability is particularly beneficial when shooting from unsupported positions or in field conditions where a steady rest may not be available. Many shooters find that the forward weight bias created by bull barrels helps them maintain a more consistent sight picture and reduces fatigue during extended shooting sessions.

Better Compatibility with Suppressors

Shorter rimfire bull barrels work exceptionally well with suppressors, making them an excellent choice for shooters interested in noise reduction. The increased rigidity of bull barrels helps to counteract the additional weight of a suppressor at the muzzle end, maintaining accuracy and reducing point-of-impact shift. Additionally, the shorter length of these bull barrels, when combined with a suppressor, keeps the overall firearm length manageable. This combination of a short bull barrel and suppressor is particularly popular among hunters and recreational shooters who value both accuracy and hearing protection. The use of rimfire bull barrels in suppressed setups often results in improved balance and handling characteristics compared to standard barrels with suppressors attached. I like rifles with short bull barrels for these reasons.

Aesthetic Appeal

While not a performance-related advantage, many shooters appreciate the robust and purposeful appearance of rimfire bull barrels. The thick, uniform profile of these barrels can give a rifle a more tactical or competition-oriented look, which some enthusiasts find appealing.

Cons of Rimfire Bull Barrels

Increased Weight

The most obvious drawback of rimfire bull barrels is the additional weight they add to the rifle. Depending on the barrel length and material, a bull barrel can add several pounds to the overall weight of the firearm. This increased heft can make the rifle more challenging to carry for extended periods, particularly in hunting or field shooting scenarios. Shooters who value mobility and quick handling may find bull-barreled rimfire rifles less suited to their needs.

Higher Cost

Rimfire bull barrels are typically more expensive than standard barrels due to the additional materials and machining required in their production. The cost of upgrading to a bull barrel can be significant, especially when considering high-quality stainless steel or carbon fiber options. For shooters on a budget, the performance gains may not justify the added expense.

Altered Balance and Handling

While the forward weight bias of bull barrels can improve stability in some shooting positions, it can also negatively impact the rifle’s balance and quick-handling characteristics. Rifles equipped with rimfire bull barrels may feel front-heavy and less maneuverable, which can be a disadvantage in situations requiring rapid target acquisition or when shooting moving targets.

Reduced Cooling Efficiency

Although bull barrels dissipate heat more effectively due to their larger surface area, they also retain heat for longer periods. This can be a drawback during very high-volume shooting sessions or in hot environments. The prolonged heat retention may lead to mirage effects, potentially affecting sight picture and accuracy over time.

Compatibility Issues

Not all rimfire rifles are designed to accommodate bull barrels. Upgrading to a bull barrel may require additional gunsmithing work or modifications to the rifle’s stock or bedding. In some cases, it may be necessary to replace the entire action to properly fit a bull barrel, further increasing the cost and complexity of the upgrade.

Overkill for Some Applications

For many casual shooters or those primarily engaged in short-range plinking, the benefits of rimfire bull barrels may be negligible. The increased accuracy potential of bull barrels is most noticeable at longer ranges or in competitive settings. Casual shooters may not see a significant improvement in their practical accuracy to justify the added weight and cost.

Wrap Up

When considering whether to invest in a rimfire bull barrel, it’s essential to evaluate your specific shooting needs, preferences, and budget. For those seeking maximum accuracy and stability in their rimfire rifles, particularly for long-range or competitive shooting such as NRL22, bull barrels can be a worthwhile upgrade. However, for hunters, casual plinkers, or those prioritizing lightweight and quick-handling firearms, the drawbacks of bull barrels may outweigh their benefits.

Ultimately, the decision to use a bull barrel on your rimfire rifle should be based on a careful consideration of your shooting goals and the specific characteristics of your firearm. By weighing the pros and cons discussed in this article, you can make an informed choice about whether a rimfire bull barrel is the right option for enhancing your shooting experience.
