JLK Bullets ???

[brianc74]

Does anyone IMO the G1 and G7 BC of the 135 grain .264 bullet.

Also. Do the bullets like jump or jam.
If the like jump. How much?

Do they make a 135? They list 130 and 140.

The jump vs jam answer is barrel specific. You need to test jump and jam to see what your barrel likes.

 

[brianc74]

Yes. They now make a 135 grain bullet. It’s not listed on their web site. That why my question.

Just Incase you are not aware, Berger has a “how to” guide on their website for seating depth testing on VLD style bullets.

After testing them jammed to establish a baseline, try .015" off...

For the .264 130 JLK's, I got good results jammed, something in the 10-12 range, but I would go deeper into the lands if needed. The other option is the Berger depth test as noted above. Swampy Milholland told me they like to jump about the same as Berger 130 VLD, which liked 30 thou jump in my rifle. Again, I'd do the Berger test until they were seated mag length, since a good load in the mag is golden.

My rifle is built on a LA. With a extended internal bdl box and follower. I have plenty of room pushing the bullet forward. Rifle is chambered in 6.5-284 Norma.

I ran the 130's with a 35th jump with great results. This was in a 6.5 Creedmoor and I had to jump due to mag feeding.

Thanks for the info. The link was helpful.
