I have been using Accurate 3100 powder in my Remington 700 Varmint Special in .243 since I bought it in the 1980's. I have about 25 loads left in the last 8 lbs. I bought at least 10-12 years ago. It has been shooting fantastic groups using the 75 grn Vmax's and the 87 grn. Vmax's. Rifle was rebuilt about 25 years ago and not shot much. I had it tuned up a couple of months ago and it has been shooting some of the best groups I have ever shot. So my dilemma is they don't make the Accurate 3100 powder anymore and I need a replacement. With the cost of powders these days I don't want to go down the rabbit hole and spend lots of $$$$ on powder that just wont work. Any suggestions would be appreciated. Additional info is : Remington 700 in .243. Rock Creek Barrel with a 8.5 Twist. Barrel is 26 inches. Heavy Barrel. Shoots the 75 grn Hornady Vmax . Thanks for any replies.
