Thread: Powder for 6.5 06 and 140gr projectile

All going well I should have the 6.5 06 up and running next weekend
What powder have folk found best in the 140gr bullet range
I have on hand ADI 2208, 2209, 2213sc and VtVh N560

looking about it seems 2209 or 2213sc would be the best bets amongst what I have?
Anything else worth a look?
cheers.

How long is your barrel??

25"

2213sc will get the best speed and probably accuracy too with that longer barrel.
RL26 would also work great

Make sure you work up - both these powders look excellent (case full and 100% burn)

My experience with 6.506ai - that 2213SC hit pressure too soon for max velocity (AMAX and Partitions 140 gn), 2217 gave better speed and similar accuracy. N560, RL25 or 26 should be ideal

Cheers all I'll try the 560 first.

Thanks For that @Tentman

Ill be interested to know what velocity you can achieve with this cartridge

I want it as a long range wallaby gun and a gong shooter so will be going for the best mix of speed and accuracy I can find
If it shoots as well but a bit flatter and naturally faster than my 6.5x55 I'll be a happy camper.

Noting we still dont have pics posted...

I haven't got the bloody thing yet
Mark was to test fire this weekend and if all good bed it into the stock ready for me next weekend.
It will probably rain.

hopefully not tears ordered dies for my project today 25" barrel sounds like a good compromise much advantage over a 24

Nah just the way it worked out.
