300 Blackout 125gr Solid Copper Fracturing Projectiles (Qty 50)

What this is

This is the 300 Blackout 125gr Solid Copper Fracturing Projectiles (Qty 50).

This is the 125gr solid copper fracturing projectile for 300 Blackout, the heavier of the two supersonic-role weights we stock in this design.

Why step up to 125gr

The extra 10 grains over our 115gr option gives a modest but real improvement in ballistic coefficient and retained momentum, which shows up as less wind drift and a slightly flatter trajectory past 100 yards. It is still a supersonic-role bullet built for rapid energy transfer, not the deep-penetration choice.

125gr versus our 115gr

If your 300 Blackout stays inside 100 yards, the difference between this and our 115gr option is marginal and either works. Past that range, or if you want the flatter of the two available supersonic trajectories at distance, 125gr is the better fit.

Frequently asked questions

Should I use the 125gr or 115gr in my 300 Blackout? Both are supersonic-role weights. 125gr carries more momentum and a slightly better ballistic coefficient for use past 100 yards; 115gr is faster and flatter at close range.

Does the heavier weight change my powder charge? Yes, always use load data published for this specific 125gr projectile rather than adjusting a 115gr load by weight ratio; the two bullets are not interchangeable in a single published load.

Is this suitable for a suppressed build? At supersonic velocity you still get a sonic crack even through a suppressor. Choose one of our subsonic-rated 300 Blackout projectiles for a genuinely quiet suppressed build.
