[QUOTE="yorke-1, post: 2204441, member: 11960"] New video from yesterday with the 7mm SAUM. [MEDIA=youtube]o2iA1HnKnts[/MEDIA] This is the first round of 7mm bullets shot at 200 yards from a 1-8.5" twist 7mm SAUM. You know those days where you'd have been better off just packing up and going home? That was yesterday for me! LOL The weather turned just as I was getting set up, so it was overcast and I had to set up a canopy to keep the gel dry. That made it relatively dark, which doesn't help to get good video. Then every time the gel blocks hit the ground, they got a little dirtier. I only had a few of the 143 HH and 155 CE MTH bullets left, so I thought I could do this without any sighters, I was wrong and they were hitting pretty high. I was already zeroed at 200 yards with the 165 TGK, so those were dead on. Here are the muzzle velocities of the loads tested. 143 HH: 3142 fps 155 MTH: 2955 fps 165 TGK: 2960 fps Here's the first shot with the 143 HH [img]https://i.imgur.com/3ASA3Kp.jpg?1[/img] Second 143 HH [img]https://i.imgur.com/ocIXRsy.jpg?1[/img] 155 Cutting Edge MTH [img]https://i.imgur.com/7ZHvzcv.jpg?1[/img] 165 Tipped Game King [img]https://i.imgur.com/EVZnAa9.jpg?1[/img] The Hammer and CE bullets just didn't want to stay in the block with all three of those bullets exiting by either curving up (Hammers) or out the side (Cutting Edge). The Sierra bullet did stay in the gel and penetrated 19.5". I haven't had time to dig the bullet out and weigh it, but it held up pretty well considering the relatively high impact velocity. The 143 HH shed about 6 petals which all exited either the top or sides of the block. The MTH left large fragments, most of which stayed in the block.
