*Note: adjust seating depth to lands. Some shot touching and some were around five thousandths off.
No truer words ever spoken! For this reason, many rifles are at their best shot as a single shot or a two shot.
Wyatt's mag box will fix some of this issue adding .120 to available OAL.
I expect groups in the 2's, three shot, repeat several times after barrel cools.
Simple wind flags are worth their weight in gold, and most are too hard headed to use them. Wind is not a constant, it picks up, switches, dies down. When you can read these simple changes, your groups shrink tremendously. Then you wonder, "where the hell have I been all these years?"
6.5 Cred with .199 freebore is on the ragged edge of being too long with the use of a vld bullet with magazine max OAL in medium length actions. So, you play with jumping the bullet to make best use of a bad situation. ON the next custom build, have .129 freebore reamer used instead of a .199 is one fix. The other fixes are to a long action on the next build with plenty of mag room to chase the leade as it grows, or go to a 6.5x47 Lapua which is a shorter cartridge.
Some rifles will shoot well jumping, some will NOT, PERIOD. You are forced to seat to maximum magazine OAL, and work up the best load for that spot. As you shoot, leade will increase to a point to where accuracy with that bullet will not be attained. At that point, going to a bullet like a Sierra 140g btsp will give you accuracy, but you will loose BC....pick your poison.
In my 6.5 creeds, the 143 eld x likes to touch the lands for the smallest groups that are bug holes. 140g Hornady bthp likes to touch the lands. 140g berger VLD hunting likes .010 off. 123g and 140g Sierra match like to touch the lands. 120 and 140g Sierra Pro Hunters have a wide range of OAL's that shoot small groups, and these two bullets are not of a VLD design.
On a custom build, design for success way down the road, not just when the barrel is new. Rem long actions and Tikka's have plenty of extra room to play with. The weight difference between a short and long action Rem build is about 6 oz.
When my barrels are shooting 5/8"-3/4" at 100, it is time for a new barrel or a barrel set back to get the bullet closer to the lands....not a small consideration.
Accuracy is a relative thing from individual to individual. You can work up acceptable loads to hunt with jumping the bullets, but it is a fickle bitch to deal with over time, especially with VLD bullets. Berger has come out with a Classic line of bullet that helps tremendously with this issue, more bearing surface, less VLD. If you have not tried any of the Berger Classic bullets, I suggest that you try some during the Holiday sales...you are in for real treat when it comes to small groups and tuning a load for best OAL.
