LL ammo testing day

First topic message reminder :

Not to happy with my Ransom Rest LL test today of my Zero 185gr JHP and SWCHP loads.  The range benches just are not good platforms to mount the RR on.  They are 1x6 boards across uprights.  The JHP did 2.15" and the SCWHP did 2.41" both 10 shot groups.  I shot the same size group using a arm rest.  I really think if I put my 2-6x pistol scope on the LB just for testing I could sell the Ransom as I wouldn't need it.  From the testing I did with the SNS cast SWCs I know that by changing the load of BE by a .1gr at a time the groups may tighten up on the SWCHPs.  I did that with the JHPs and the group tightened up till I hit 4.1gr then after that started opening up again.  Don

if memory servers the frame slips down into the rectangular piece and the rear bolts tighten it... but, it's been a long time since I saw one.. I think Jon is right that the AMU had one ..

If you are getting 2.15 off of a wooden bench, you have a decent load. Are you testing 30 rounds or 10?
