JLK, 6.5 130 gr bullets...anyone measure the BC?

[buckbrush]

Does anyone have a BC, either G1 or G7 for the 130 gr JLK? Their website shows the exact same dimensions as the 140 gr leading me to believe there are typos.

Thanks.

Its possible that they use the same dies and just a lighter core. If that is the case, then their form factors are the same, which would place the BC for the 130 around .303 G7...

When Jimmy Knox originally made these for me back in 2005, i found the BC to be .030 less than the 140.

The first Berger 130's were almost identical to the JLK, but current Berger production had increased the bearing surface length in current production do not sure how close the JLK 130 is to the Berger 130.

I find the over all length to be a lot shorter than he states on the site,but it's still longer than the berger....jim

I also questioned the identical specs for 130 and 140 gr JLKs and was advise by JLK (Swampy), "Specs are OK. Same externals. Internals are different."

I also asked Berger about their lengths - response: 130 = 1.400, 140 = 1.421.

Let get it right if bergers are shorter than the JLK's on a number of different lots i have and how can the Bergers have length of 1.400 for the 130? when the JLK's are from 1.360 to 1.380 and most of the time they are ar the low side of 1.360. Somebody's blowing smoke.........jim

Not sure of the BC, but johara1 is correct on length.
The bullets I have measure;
JLK 130=1.368
Berger 130= 1.369
The Berger has more bearing surface length by about .040. That being said, I would think the JLK
would have a higher (number) BC. The old Berger 130 BC was .595 (G1) so the JLK would be in the
.600-.610 area.

Gary,
I'm not sure of the BC. but the JLK's shoot 5-6 clicks flatter at 500.........jim
