Hunting rifle shooting varmint varminter 6BR .223 22-250 precision 6mm powder reloading bullet Lapua Norma VHA Nosler Sierra

"The 6mmBR has a lot going for it--while it is not the fastest 6mm cartridge it is fast enough and very efficient. You can push a 55 grain Ballistic Tip 3800 fps. That is as fast or faster than a 22-250 shooting the same grain bullet and you have a higher ballistic coefficient. Where I think the BR really shines is when using 65-75 grain bullets. Good velocity, good wind cheating, low recoil, little powder use, easy on the barrel and inherently accurate. What more could a varmint hunter wish for?" -- Mike Delbo

Velocities are based on a 25" barrel and standard 6mmBR Norma case. Note, velocities may vary considerably from gun to gun, and even barrel to barrel. Primer brand will also alter velocities. Always start 10% low and work up.

WARNING: With all loads, ALWAYS START 10% LOW and work up incrementally.

WARNING: ALWAYS start 10% below these loads and work up. NEVER assume pressures will be safe if you change ANY component. Case web growth is probably the most reliable indicator of over-charge. By the time you're getting stiff bolt lift or cratered primers with fresh brass you've exceeded proper pressure levels. Ambient temperatures and seating depth can alter pressures considerably. Don't assume cold weather loads are safe in summer.
