[QUOTE="bigmoose, post: 396977, member: 25231"] If you are still in need of 300 ICL Grizzly reloading advise, I may be able to help. I know there is not much out there for that caliber but I've had mine for about 35 years and it is my favorite rifle. I know of two other rifles that see use every year out in the field also. My Dad has one and a good friend also shoots one. All three rifles are re-chambered pre-64 Winchester model 70's that started out as 300 H&H. If you have one of the custom jobs that Juenke's built then you have quite a fancy gun ! They were good shooters too and made good long range rifles. I remember a photo hanging in their shop of a mule deer buck that Arnold shot at 700 plus yards.gun) Anyway, I do not load any of the lighter weight bullets in mine. My Dad and I both shoot 200 gr. bullets. Used to be we could only find 200 gr. Speer Spitzers and that is what we used for many years. Even they were special ordered. You can not hardly beat 200 gr. Nosler Partitions although I've loaded up some 200 gr. Accubonds lately and find them very accurate. Looking forward to the new (this year) 200 gr. tipped TSX's. One thing I should mention is the case selection. You can use 300 Weatherby and 8mm Remington Mag factory cases by just running them through your sizing die and trimming them all to the same length. Pick the shortest one and go from there. The 300 ICL was based on the 300 H&H case and you can make your own. This can be a pain as the 300 H&H case has a long taper with little shoulder. When you fire form the case it will have a very pronounced shoulder. You can load reduced 150 gr. loads but you will still lose many cases to splitting necks.

Make sure these will fit in your magazine. Loads in my gun are : 200 gr. Accubond (or Nosler Partition) 78 grs. IMR 7828 215 Federal primer This load is a Max load and is right at 3000 fps. 200 gr. Accubond (or Nosler Partition 76 grs. H 4831 215 Federal primer This load is a Max load and around 2900 fps My Dad's gun will take another grain of powder and not show pressure signs.
