N205 and RL17 in 6.5 creedmoor

[wboggs]

Has anyone used either of these powders with bullets 140 and up in a 6.5 credmoor? I would be interested in your experience?
Thanks

I have used R17 in the Creed a few times. Load data is essentially the same as H4350 with velocities slightly higher than what's achieved with 4350. 41-42gr is generally the sweet spot in a creed with the 140 class bullets with either powder. R17 is not as temp stable as 4350 though, you will see some velocity variations in extreme temp swings.

N205 is next to H4831sc on burn chart. H4831sc is my go to powder for 140 gr bullets.
I tried RL17 for a bit, it would shoot excellent one day and not so good another day, seemed like it would go from mild to wild real fast.

That is bad news on RL17. Unfortunately I have about 7#s. I do have a fair amount of N- MRP and some 205 which I might give a try when my H4350 runs out.
I bought the RL17 for a long range 30-06 I had throated for 225 bergers

Not that there's anything wrong with rl17 but can you get more

More velocity, consistency, temp stability?

17 is hard to get. i have just enough for testing. 8208 gave more speed with the 100 gr

Oh, I see what you meant. I already have a large supply. Almost all comments are negative.

I shoot N204 and 4350 with almost identical performance in my 6.5's

I don't have a 6.5 but do have 2 6mmCM's. The best group I ever shot with my RPR 6mmCM was with RL17, a 10-shot group at 100 you could cover with a nickel with room to spare. 41.7, Berger 108BT, Fed 210M Hornady case.

RL17 has been my powder of choice for 6.5 Creedmoor from the beginning. I've had great velocity (compared to H4350) and really haven't noticed enough change with temperature to harm accuracy.
Guess I've been lucky or maybe inattentive but .1mil change at 1k isn't a worry for me when I shoot the Creedmoor.

What weight bullets are you using with the RL17 and velocity compared with H4350?

I usually shoot the 142SMK or 140 Hybrids.
Velocity usually just over 2900 with either bullet.
I really will need to look at my data before giving you actual numbers.

Close enough. I might try it out since I have a lot which is not being used for anything.
Thanks
