First off I will say I dont have experience with the platinum bullets but I do with the copper ones that are tipped. I shot the 348 grain in mine. Same twist rate with 100 grains loose 777. Shot amazing. Preformed horrible. Flat as a pancake with only 8 inches or so of penetration on a broadside elk with the only bone contact being 1 rib bone. Then following year took 3 shots over several miles of tracking to finally put a smaller cow on the ground. I switched up to Harvester Hardcast 330 grain. Again same twist rate as your gun. It is in a sabot. I lube the sabot with bore butter. If I do my part off a bench with open peep sights and a 6 o'clock hold I can keep 1-2 inch groups at 100 yards. Shooting 90 grains 777. 3 bulls and 3 deer since. None went more than 20 yards. All complete pass through. Lots of damage too. 2 shots on elk were 135 yards and 155 yards. Then on the third I had a steep quartering away shot that entered behind the last rib on one side and exited through the shoulder on the far side.They are really cheap too for the amazing performance that I have seen. I buy in bulk from the Harvester website. 50 sabots and 50 bullets with shipping I believe kept me under $30.
Bullets arrived today. There customer service did amazing and they did an added bonus for me as well with a note to go with it. Very fast shipping. Very happy with harvester company. Can't wait to see how they shoot.
