they're about as close to a 6 of one and half a dozen to another as you can get. the Edge might hold a couple grains more powder, but because of the brass, the Lapua gets about the same and maybe even "edges" out the other in velocity.
I have a 721 action here thats more than likley gonna get built to a 338 Lapua Improved with a 30" barrel , the bolt will be replaced with a PT&G bolt , with this big of a case rim is the Sako extractor as good as say the custom M-16 style?
The plan is to get a 300gr SMK to 3000 fps , is that possible with the 338 Edge in a 30" barrel?
As to this post , I realy like Lapua brass but the 338 suff is steep hopefully for a hunting gun one will only need 100 pieces. I'm kinda torn between the 338 Edge and 338 Lapua imp , I know the latter will have more speed but their is the hassel of fire forming the case and the case cost.
Any of you guys know what kind of differance in drop and windage 200fps would have on a 300gr SMK at 1000yds?
I put in 2700fps and 2900fps into JBM balistics calculater with the advertised .768 BC for the 300gr MK. These are the low end and top end of what "I" think a 338Edge could do. It shows a difference of 4.2 moa drop and .6 moa full value 10mph wind.
Courage is just fear that has said it's prayers.
The people trying to say the 2nd Amendment is outdated are probably the same folks that would say the same thing about the Bible.
