Have loaded 1000 rds for use in my LC Carbine and Thompson 1927A1. Feeds and fires perfectly in both with better than acceptable accuracy. My new go-to bullet for fun plinking.з>

These do create a slightly visible ‘belt’ in the case, being .356 diameter, but perform just like the Speer 147g HP, at a fraction of the cost for training. No issues with feeding/cycling in my finicky PSA 8″ Shockwave when…з>
Berry’s 50 Cal Muzzleloader Bullets Redefine Hunting Bullet Performance
Our Blue Diamond .50 cal muzzleloader bullets stand out from competitor offerings with their perfect balance of penetration and expansion. The full bore diameter design ensures maximum energy transfer upon impact, while the polycarbonate tip initiates controlled expansion for devastating terminal performance.
Choose from three different bullet weights to match your hunting needs:
- 250 grain bullet: A light muzzleloader bullet for manageable recoil and a flatter trajectory when hunting deer and similar-sized game at typical hunting distances
- 275 grain bullet: The versatile all-around performer that balances trajectory and knockdown power for most big game hunting situations
- 305 grain bullet: Our heavier bullet option delivers maximum energy for larger game like elk or black bear, with superior weight retention for deep penetration
Each bullet features our flat base design for enhanced stability and better accuracy at long range. Paired with our proprietary sabot, these bullets achieve their full potential in high-performance muzzleloaders, delivering round after round of consistent accuracy out to 200 yards and beyond.
Our Bullet-Making Process
Starting with a Solid Core
Every Blue Diamond bullet begins with a critical element – the core. At Berry’s, we use a technique called swaging to form a pure lead core under high pressure. This method ensures uniform density throughout, contributing to the bullet’s stability in flight and consistent accuracy.
The Copper-Plating Process
Following core formation comes the key to our bullet-making magic – electroplating. Each swaged lead core is immersed in a copper cyanide solution where an electric current creates a controlled chemical reaction that deposits a thin yet sturdy layer of copper onto the lead core. The result is a bullet with zero lead exposure.
Re-Striking: Refined and Perfected
After electroplating, the bullets proceed to be re-struck. This involves passing them through a die to achieve precise specifications for overall length and caliber. This re-striking process reinforces the bond between the copper and the lead core while smoothing out any imperfections from electroplating.
Quality Assurance: The Final Step
Before shipping, all our bullets undergo rigorous inspection to ensure they meet our standards for accuracy, reliability, and performance. This attention to detail provides consistent performance shot after shot in your muzzleloader.
Why Choose Berry’s Bullets?
Berry’s plated bullets offer significant advantages over both jacketed and cast options. Unlike cast bullets that can leave lead fouling in your barrel, our copper-plated design ensures clean shooting with no lead exposure. Compared to jacketed bullets, Berry’s plated bullets deliver comparable accuracy at a better value.
Our .50 cal muzzleloading bullets feature:
- Consistent bore size with our sabot system for reliable fit
- Superior weight retention for deep penetration
- Polycarbonate tips that initiate expansion for impressive terminal performance
- Match-grade consistency from our precision manufacturing process
