You are looking at a nosler book to get that and is not correct. Exactly what I'm talking about..Nosler No. 3 Book states in the 7 Rem Mag, that 67.5 grains of RL 22 pushing a 140 gets out at 3340 thru a 23.5" barrel..???? Now I ask you.. are these 2 calibers even in the same ballpark or do you...
I'll have to look up the lit but it's 79.5 of RL22 thru a 26" Doug Sup air gauge 1 - 9 barrel with the proper free bore.. I'd have to measure that if you needed the info.
Also about the reloading manuals.. I don't know what's going on with them all but the stats are different from book to book...
Hi all, new here but here's my .02.
A few are speaking to the 7mm and I can tell you this for sure, after building a 7MM STW in a 26" barrel it's forever ruined the chances of the other rifles ever seeing the field again.
Being limited to a 140 grn. or a 160 grn. is not to bad especially...
