In the Hornady 10 edition using Varget podwer the 223 service rifle data is around 100 FPS slower than the 5.56 data using the same charge the data is from a 20 inch barrel with 1 in 9 twist for both guns everthing is the same would it be the case? 24gr using 5.56 is 2800FPS 24.9 gr with 223 is 2800 FPS why is this? Should I use 556 brass only for 556 load data ? will be shooting this out of the springfield saint.
Hey Guys, I'm looking to get my first rifle and I kinda settled my mind already. The problem is that I have limited experience and wanted to get some opinion from people who have first hand knowledge. First I'd like to explain where I'm coming from. I'm 23 and I come from Germany. I've been shooting since I'm 14 and got my owning licences for almost 3 years now. I'm somewhat limited in gun ownership so need to be sure about what I want. I'd like to get a rifle that can do almost everything. Diciplines including: 100m static, 300m static, 500m static, multi distace dynamic, maybe some IPSC. My primary goals are a little bit different though. I also would like to use is for hunting in the future and I really want to tackle the 1000m mark. I found a local gunsmithing company who's making custom ARs only. I haven't talked to them yet because I wanted to get more data. My plan is a lightweight AR-10 pattern rifle with a 16.5" Barrel chambered in 6.5CM. On goes a IOR 2-16x42. My Question is, is that possible? I mean, I did the maths and theoretically it should be. I just want to hear some expert opinions. Thank you guys!
