Curious on where you seat your bullets

[Alex Wheeler]

For those that have a well tuned rifle, are you in the lands or jumping, cut rifled or button barrel?
Thanks

Jumping with Berger Hybrids or Juggernauts (308)........Bartlein (5R), Krieger (4 groove), & Brux (4 groove), all cut rifled barrels.

My 6 Dashers use Berger and JLK 105 VLD's. BOTH like them to be 12-13K into the lands. My .284 Shehane uses 180gr Lapua Scenars set 3-4K off the lands. My .260A.I. uses a Berger 140 LRBT set 7-8K into the lands. ALL are Krieger barrels except 1 Dasher>>it is a Bartlein. As you know, all are cut rifle barrels.

Pretty sure you will find there is no pat answer, each rifle and bullet are unique from my experiences.

I have read so much about Berger VLD have to be seated into the lands to shoot good. My 2 most accurate rifles that would turn them into single shots seated into the lands. The 6.5-284 Cooper does well with them seated .01 into the lands but I am not a good enough shot to tell the difference with them seated .08 off the lands, both locations shoot well. The 22-243 does well with 80gr Berger VLD .05 off the land, These are not target rifles but hunting rifles with classic type stocks but shoot well under half MOA with loads tuned to them

Howdy !

For mine.... .002" off the lands, and has worked well both cut-rifled & button-rifled
( my loads / my guns ).

YRMV.

Thanks guys,
Was talking with Tom the other night and we both found that the only barrels that seem to like jam were our Broughtons. I just thought it would be interesting to see if there was some trend.

In my Liljas, all like it 0.015" jump.

Alex, were those 5c or canted lands on the broughtons? What I have seen commonly regardless of type 3 groove 4 groove 5 groove etc. is most always there will be a spot from .015ths off to light engagement where rifle will perform at it's peek, but tight engagements most always come with poor results for me with the exception being canted lands like broughton, Bartlein and so on. Regardless of caliber most all at times even shoot best with extra engagement, but in most applications they are field rifles so I try to find a spot off the lands for reliability reasons. Not sure why but I suspect it's in regards to how bullet engages lands, canted lands having less contact maybe, less deformation to jacket, less surface friction. Interesting none the less, then you throw bonded bullets into the mix and that's a whole new beast.

Jumping 180gr hybrids in a Bartlein 5R barrel.

I don't think there is a bullet I am using where I am not jumping, but then again I run mainly SMK, Hybrids, and A-Max's, all of which are typically shot better jumping than jamming.

.013 in the lands with 185 Match VLDs.

I run low neck tension. (.0005-.001)

 

[Alex Wheeler]

Yes they are 5c barrels. We tend to run heavier neck tensions as well.
