Bea175: I have three Varmint Rifles in caliber 17 Remington - they all prefer the wonderful Berger 25 grain bullets.
Two of them prefer good old H 4895 and the third likes IMR 4320.
I do have some N 133 that I use in my Sako 6m/m PPC - have you heard something "good" about the N 133 in the 17 Remington?
I sure like that powder but it IS expensive and hard to find in my neck of the woods.
IF... you are looking for a powder for the 17 Remington be sure and try H 4895.
I have a kind of rare 26" barrel Remington 700 stainless Varminter (VSS) in 17 Remington and it shoots extremely well with that H 4895 powder.
My best group (5 shots at 100 yards) to date with this Rifle measured .241"!
Good luck gathering info.
