308 Win 175gr Solid Copper Fracturing Projectiles (Qty 50)

What this is

This is the 308 Win 175gr Solid Copper Fracturing Projectiles (Qty 50).

This is the 175gr solid copper fracturing projectile for .308 Winchester, the heavier of the two weights we stock in this design. It is the choice for reloaders shooting past 300 yards or on larger-bodied game, where retained energy and wind resistance matter more than the flattest possible near-range trajectory.

175gr versus the lighter 152gr

The extra 23 grains buys real downrange advantage: 175gr sheds velocity slower and drifts less in wind than the lighter 152gr, which is why it is the traditional long-range and big-game weight in this caliber. The tradeoff is a slightly more curved trajectory inside 300 yards, meaning more holdover at moderate range than the 152gr gives you. If your shooting stays inside 300 yards on deer-sized game, the lighter option in this line is arguably the easier bullet to shoot well; past that, this is the one to load.

Twist rate matters more here

175gr is a longer bullet than 152gr at the same caliber, and it needs a faster twist to stabilize reliably, 1:10 is the realistic standard, which most modern .308 rifles are cut to. Older rifles at 1:12 can be marginal at this weight, particularly in cold air where stabilization margins tighten. Confirm your barrel’s twist before loading a batch around this weight.

Lead free construction

Solid copper, no lead core, fractures on impact. Same non-lead compliance benefit as the 152gr.

Frequently asked questions

Will this stabilize in a 1:12 twist barrel? It can be marginal; 1:10 is the safer, standard twist for 175gr.

What is the practical difference between the two weights you sell? 175gr retains energy and resists wind better past 300 yards; 152gr is flatter and easier to hold at closer range.

Are these safe to use in an AR-10 pattern rifle? Yes, subject to your rifle’s published pressure and magazine-length limits.
