Re: 264 win mag vs. 7mm rem mag
I think I can do better than that. Since their is so many doubting people I am building a Browning A Bolt (yuck) for a close friend of mine and will be finishing up this week I will video tape on the chrony what results I get. This will be interesting for me also. A factory barrel that is only 26 inches long. The COAL is not as far as I would like it but it does seem to work well in the modified Browning clip. The throat is of coarse what I put in all of my rifles I do not put the SAMMI spec 3 degree angle in it. I instead put a 1 degree minus 30. It matches the 175 Nosler LRAB much better and helps with the accuracy I want to achieve in all of what I build. It puts less strain on the bullet jacket ( Berger) This bullet will be seated .010 off this style of lands. This is tighter that I normally want but the customer is always right. The internet has made him a expert. If it was my own I would have it .035. Loads will be worked up from a starting point of 72 grains of RETUMBO in a Winchester case, Fueled by a Winchester MAGNUM primer. 3.5 in COAL. I typically like 3.7 with this bullet. I really am anxious what this puts out. If I had to bet on the 26 in factory tube and the shorter COAL with this seated so minimally off the lands I would guess 3150 as a minimum velocity Depending on if the barrel is Fast, etc. I must tell you that all bullets are MOLY coated. I will tape this and put it on this forum. Lets see who can guess the closest!!
