The chart below is computed using the same G7 point-mass engine that powers the Long Range Science calculators, using the Berger 135 gr LRHT as a reference load for the 25 GT. The 25 GT has no factory-loaded ammunition yet — this reflects the Berger 135 gr LRHT handload most PRS shooters are running, built on necked-up 6 GT or dedicated 25 GT brass. Treat it as a starting point — always true it to your own rifle and chronograph.

Drop and wind are come-up corrections (dial/hold up). Wind is a 10 mph full-value crosswind via lag-time approximation. Values assume a 100 yd zero and standard atmosphere.
These numbers are a reference load, not verified DOPE. Differences in your actual muzzle velocity, barrel length, and local air density shift the solution — especially past 600 yards, and even more once the bullet slows toward the transonic zone. Confirm your true velocity with a chronograph and validate on steel before trusting any chart downrange.
Key Takeaways
- Supersonic to ~1,467 yards — one of the longest supersonic ranges on the site, a big draw for shooters stepping up from 6mm.
- Holds 1,000+ ft·lb to ~738 yards.
- ~2.8 MIL / 9.7 MOA at 500 yards, ~8.5 MIL / 29.1 MOA at 1,000.
- ~1.8 MIL of wind at 1,000 yards in a 10 mph full-value crosswind — flatter and less wind-sensitive than most 6mm PRS rounds, part of why the .25s are gaining ground fast in competition.
Frequently Asked Questions
How much does a 25 GT drop at 1,000 yards?
With the Berger 135 gr LRHT at 2725 fps and a 100-yard zero, roughly 8.45 MIL (29.06 MOA), about 304 inches, under standard conditions. Your exact drop depends on your true muzzle velocity and air density, so true your data before relying on it at distance.
Is the 25 GT supersonic at 1,000 yards?
At 2725 fps it retains about 1550 fps at 1,000 yards and stays supersonic to roughly 1,467 yards. Colder, higher-altitude air extends that range further; hot low-elevation air shortens it.
Should I use G1 or G7 BC for the 25 GT?
Use G7 for this bullet’s boat-tail match profile — the G7 standard projectile matches its shape, so the drag curve tracks reality better across the trajectory. This chart uses a G7 BC of 0.334 (G1 0.65).
What zero does this 25 GT chart assume?
A 100-yard zero with 1.8 inches of sight height. A different zero shifts the whole table — enter your own zero in the Ballistics Calculator to regenerate it for your setup.
