130 & 140 JLK Questions

[OzzyO20]

In an attempt to hunt down some 140 grain hybrids locally, someone suggested I look at the JLK line by Swampworks. The company history is appealing, and I appreciate the effort they put into making each round. However, there is next to nothing out there (or my Google fu is weak) on them besides a few hunting threads and some older info. Does anyone have the G7 B.C.'s for reach round? Never messed with a VLD round, but I did at least read these were less depth sensitive than some others.

I'd be loading for 6.5 CM, 1:8 twist, 24" AI factory AT barrel using H4350 and 205M primers in Lapua SRP brass. I have a match in less than a month so I'd need to order quick and get a load together and some practice in before hand. Otherwise I'll just snag some 130 Berger Hybrid AR's and go with an older load I have that works well.

Thanks in advance.

Oh dang, that takes care of that then. For the time being anyhow.

you can sometimes find 50-100 on here to try before you order a big batch from him

maybe you can call him and he'll have some extras but i wouldn't count on it

Wait time aside, do they live up to the hype? I understand there is no guarantee that bullet x works in gun y, but I'd put in an order for down the road if they perform half as well they do on paper.

I was unfamiliar with them, but they are much cheaper than the burgers. How do they compare?

I ended up with some 130's in a trade a while back and used them in a 6.5 Creedmoor. The G7 was around .320. They were not depth sensitive and have been the most accurate and consistent bullet I have tried to date in two different rifles. One was a criterion barreled savage and the other was a Schneider barreled Remington.

The G7 is .320 ???? Holy shit balls. The Berger 130 hybrids are around .287.....

they G1 around .620 and he'll point them for you for another BC gain. worth it

I originally had an order that i should have been getting right now, but I'm waiting on a 6.5 Hancock so i told him to push me back a few months

Yep, verified out to around 1300 and moving around 2900fps.

Man that's incredible. I'm going to have to call later today and get on the list.

JLKs are good to go if you order well before you need them.

Don't be afraid to jump them some either, I ended up around 65 thousandths if I remember correctly.

I need to do more research, but jump still confuses me a little bit. I know with the Bergers I was .020" off the lands, I think that's set back. Is jump/jam the same or different??

typically we jump. .020 give or take AWAY from the lands. but some bullets seems to like around .065

benchrest guys or guys fireforming typically jam .015 or so INTO the lands

Thanks for clearing that up. I've seen a few terms kicked around and got them jumbled up.

I've shot the 130 jlk's out to 2326yds. First round hits from 700-1640yds. I used a G7 of .315 in those conditions.

 

[Supersubes]

I shot many thousands of the 130 for a 6.5x47. Good bullets, and I still have a few thousand or so. From memory I was using a .300-.305 bc for mine. As has been stated, gonna need to plan ahead if you want to use them. Swampy takes orders, then does a run of them.

 

[craigos]

i went for the 135s for everything 6.5

I was fortunate enough to score 600 of the 130s from a member here. When they arrive I’m gonna try them out and get on the list if they shoot half as good as people say.

 

[Will65284]

I forgot to mention that my data was from pointed 130's to get G7 of .315
