Goldtip, I've been hearing good things about the 150 sciroccos. They were back-ordered everywhere I checked, for about 6 months, but I finally tracked down a box. I haven't shot any yet, but a couple of my friends that have 300 rum's shoot the 180 sciroccos and have had good results. Also bought a box of the 175 gr A-Frames. Looking forward to seeing how both those rounds shoot. Although, it's hard to argue with the 160 gr Partitions I have that shoot into 3/4" groups. I'll try and take a picture of my gun today and see if I can figure out how to put it on here (this will be my first ever attempt at posting a pic anywhere). |

Blacktail, the reason my brother went with 150gr scirocco's was to take advantage of the unbelievably flat shooting capanilites of the 7RUM. If you look through reloading manuals and use tested loads without really taking chances, then the 7RUM with the 175gr bullets actually shoots less flat than a handloaded 300win with 180gr bullets. And I'm here to tell you I've seen that 150gr scirocco drop a couple of 310-320" bulls right in their tracks out to 400 yards. :o It hits hard and shoots flat. If they are accurate out of your gun, you will not be disappointed. It will rattle your teeth at the bench however. :chuckle: |

Just my opinion, but to me the advantage in a RUM is the extra powder capacity of the case, which allows you to use a heavier bullet at the same velocity as another 7mm cartridge that has a lesser powder capacity such as the 280 Rem. and 7mm Rem. Mag. You're really not taking full advantage of all that powder you're burning by using a light weight bullet with a low ballistic coefficient. A 7mm 150 grain bullet is well suited to a 7mm/08 and at the upper end a 280 Remington, but for a 7 RUM, I'd go with a 160 at the very lightest, and 175 would be even better. The heavier bullets have a higher ballistic coefficient, and while they may be slightly slower at the muzzle, they retain their velocity better at longer ranges, and do not get pushed as much by the wind. And there is your big advantage in using a RUM...the ability to shoot way out there past 300 yards and not have to worry about the wind drift as much. Wind is much more difficult to compensate for than distance. For distance we have rangefinders to help, for wind we have what? Just a wild assed guess? Study ballistic tables and play around with ballistic calculators, you'll see that the heavier bullets win every time. The only reason to go with a light bullet, is to reduce recoil. |

bobcat is Spot on.....as usual. The 175's in 7mm are hard to beat for BC (wind cutting ability). Lighter bullets may be faster out of the muzzle, but velocity will erode much faster in a lighter bullet than a heavier/higher BC projectile. |
