Reload load data 6mm powder bullets Hodgdon Vihtavuori Lapua
We could fill a book with 6mm BR reloading recipes, case prep secrets, accurizing tips, and miscellaneous voodoo. Or we could tell you simply take a new Lapua 6BR case, add a CCI 450 primer, drop in 30 grains of Varget, top it with a Fowler 80gr FB bullet at the lands, and shoot it.

Chances are that can give you a .30" group at 100yds in a good gun. But for those of you who won't settle for the simple answer, here's a summary of things that work...

Preferred Powders
For the 70-90 grain bullets, Vihtavuori N-135 and H4895 are excellent choices. For the 105-108 grain projectiles, A good starting point is Varget sparked by CCI 450 primers. That's a combo proven in competition. Varget is accurate, works with all bullet weights and is relatively insensitive to temperature shift. Our recent Rail-Gun Tests, however, have shown Reloader 15 to be equally accurate, and able to deliver up to 50 fps more velocity with the heavier bullets. H4895 also proved very accurate with the heavier bullets in the 2880 fps range. Other good choices for the heavy bullets include VV N-140, N-150, N540, and Norma 203-B. Reloader 15 has produced great velocities with low ES, giving more speed than Varget at similar pressures. Norma uses 203-B in its Diamond Line 6BR ammo.

Best Bullets
For short range: 80gr Fowler FB, 74gr Berger FB, or any of the good 68gr custom bullets.

For medium range or 1:10 twist barrels: Berger 88gr Low Drag FB, BIB 95gr FB, or Hornady 87-gr V-Max. The BIB is superbly accurate, having shot sub .2" groups at 200 yards.

For long range: 100gr Clinch River VLD, Berger 105gr VLD, 105gr Lapua Scenar, or 107gr Sierra MK. The value choice is Hornady's 105gr A-Max ($14/100 at MidwayUSA). For 6XCs, go with the DTAC 115gr VLD.

Primer Selection
CCI BR4s and 450s are giving the best velocities, with lowest ES, for the 100+gr bullets. For the shorter bullets, the Fed 205s work well. Federal 205s give good accuracy, but they don't handle high pressures as well as the CCIs, which have a harder cup. Stick to CCIs for hot loads.

Case Prep
Always chamfer the mouth before seating. We use a standard Forster 45-degree tool, then smooth the chamfer with a bit of green nylon scouring pad. Be sure to remove all burrs--don't leave any sharp edges on the chamfer. You may also want to try the K&M 4-degree tapered chamferer, but don't cut too deep--a slight chamfer is all you need. About flash holes--we suggest leaving them alone when using Lapua brass. Our tests suggest that ES and SD may increase with ANY modification of the Lapua Flash-holes, which run .15mm (.059") out of the box. If you do decide to debur the interior flash hole, use a K&M or Sinclair deburring tool for small primer holes--but be gentle, don't ream the hole out. To uniform the outside of the hole use the Sinclair 07-3000 outside PPC/BR flash hole reamer. This will ream the hole to fit a standard 1/16" decapping pin.

Seating Depth
When working with an untested load, we suggest starting .015" from the lands. However, our testing with multiple bullets in a 6BR rail gun shows that most 6mm match bullets bullets perform best seated to slightly jam, perhaps .010"-.015". However, this is not always true. We have observed that some of the heavier boat-tails, Sierras especially, perform best jumped by as much as .025". We've heard similar reports from the 6.5-284 shooters running 142 SMKs. But other guns perform better with bullets jammed in the lands .010" or more. You have to experiment to find out what works best.

Favorite Recipes
There is no "screamer" load that works in every rifle. Your barrel twist will also dictate the bullets you can run. Moreover, there are some great loads that exceed the powder-makers' recommended pressure levels, and we can't print those here. But still, here are some proven loads that should get you well on your way to shooting bugholes.

WARNING: ALWAYS start 10% below these loads and work up. NEVER assume pressures will be safe if you change ANY component.
