HuntnShoot: All three of my 17 Remington Varmint Rifles prefer and perform wonderfully (lethality wise) with the Berger 25 grain bullets.
Two of them prefer H 4895 powder and the third likes IMR 4320 powder best.
I use Remington 7 1/2 primers in all of them.
I use "molied" Bergers in one of my 17's and think its worth that effort.
I have tried all manner of 25 grain bullets in my various 17 Remingtons but never tested the 20 grainers.
Best of luck to you and good luck selling that Rifle when the time comes - but I say keep it, for old times sake, if nothing else.
I am sure if you do sell it that the day will come when you wish you had it back.
Hold into the wind
