[QUOTE="Broz, post: 901104, member: 7503"] This is the problem when comparing a 7mm RM and a 300 win Mag. Some wish to use the same weight projectiles. That is tipping the table to favor the 7mm. They are two different bores, they are not the same, so why handicap the 300? I say lets use some of the largest , highest BC bullet commercially available for both. Which ever complements each caliber, the best choice available for both. Like the 180 for a 7 and the 215 for the 300. We are talking about long range ballistics here. This is where higher BC's pay off. So why, when talking long range would anyone load a 168 in a 300 win? Maybe years ago when we didn't have the great selection we do today, but today the 300 win mag at long range will retain more velocity, have more energy and less wind drift than a 7 Rem Mag. Why would any owner of either caliber, that was wanting the best long range performance, choose a lighter lower BC bullet for either? They wouldn't. As for recoil, put a JP tactical compensator of either rifle and let even the kids shoot it. I took a 13 yr old girl in for her first elk this year. She shot my 300 win with a 215 Berger. I had her dry fire a few times then she stoned her elk at 601 yards. After, I asked how the recoil was compared to her 243. She replied "there was no recoil" Jeff [/QUOTE]
