Hi, I am fairly new to this forum and I am trying to work up a load for a 7mm Remington mag. I have decided to try out the Hornady A-Max 162 gr. bullets. I was wondering how accurate the Ballistic Coefficient numbers Hornady gives for these bullets are. I was hoping some of you might have tried them at long range and have tested to see how accurate the .625 BC that Hornady gives for them is.
I have not tested the 7mm A-Maxs much but I have the 105 gr 6mm, 140 gr 6.5mm and 208 gr 30 cal and they all were very close to actual BC measured from bullet drop over 1000 yards.
Within 1/2 moa of actual bullet impact. This variation was due to variations in my shooting location I am sure so I would say yes, they are pretty accurate from the get go. You will need to tweak your drops no matter what BC you start with but they give you a very quality place to start your drop development from.

I am Dave Kynoch; but, I am the son of your friend Dave Kynoch. I have heard a lot about you and I even have a 338 Allen Mag. Cartridge and the Exbal printout for it that you sent my Dad last fall. I have been wanting to get into long range hunting so I put together a 7mm Remington mag. I have been shooting some long range f-class matches and I am trying to get my 7mm ready for a match next week. I have found this forum is a good source for information. It would be good to meet you sometime.
