Got out for a little shooting this morning with my 338 imRp. started at 1600 yards on large rocks, Running 300 OTM bergers pointed .858 B.C . at 3025 fps. 70/44/29.35 were the kestel 4500s conditons. Wind left to right. 6mph . Dial up to 41.75 and 4 moa dial for wind hold. I aimed at the white spot on rock that we always shot at. Its about 1 moa in size, we have Milled it several times. Fired and actual got with in about a couple of inches of my mark perfect hight just need a little more windage!! Man I was happy. Cold bore , first round, almost perfect wind call. I fired 9 more rounds. 2 went a 1/2 moa high and 7 were with in the 1 moa white spot on the rock! Moved next to 1900 yards. Theirs a crack in the rock. Vertical. its 6 ft. The width is 18 inch. Dialed up to 56.75. First rd a little right. Forgot to add some wind. Made new wind call. 5.25 moa . Next 5 went right in the crack!!! Don't now group size but crack is under 1 moa. Its cool to see, because you can see the dust come from in side of the crack! I was having agreat time till I found out I only brought 20 rds. I let gun cool for 15 mins . Took last 4 shoots at large flat rock at 2307 yards. I dialed up to 82.25 moa. Large flat white rock. Car hood size. It puts of good white puffs of dust when hit. Dialed 8 moa. First 3 round neither me/ threw the scope or my spotter threw 20x60x80 Leupold, could see impact? Finally by some mircle on the VERY last shot we both saw it!!! It was High= 1 moa and 1/2 moa left. Had and over all great time burning 20 rds!!! Just thought I would share! The Whidden bullet pointer on the 300 OTMs is giving me about 6% increase in BC from my calculatins.
