Does anyone know or have heard yet when Litz plans to test for BC?
130gr weight bullets are about perfect weight for most comon used 6.5 cal, wonder why they didnt drop weight to 130
136 just dont make much sense
Hoping Hornady will do a high BC 130gr Amax in 6.5cal
I also preordered mine from Grafs. Let us know what you you have to do for loading please
I like using a .292 bushing for my 260 rem and lapua brass.
Thanks pat for your info. I am loading 43 grains of h4350. Avg muzzle velocity is 2,928 fps. SD is 10. Loading .010" off lands.
The caliber I am running is 260. The action is a remington 700 action . SAMMI Specs. I am running a 26" Broughton 5c Barrel. Went to 1k today. Held 3 shot 6" group at 1k. I then went to 1,100 yds and 1,200 yds. Bullets were entering transonic flight and did not do well. Will Post more results.
I shot these out to 1350 using the G1 BC of .700 out of a 260 Remington at 2800 fps.
dworrel,
Thanks for the info, but i can't see the g1 b.c for the 136 grain scenar being .700. Did you mean .600? So was your dope consistent with what your ballistic program or range card was telling you or did you have to tweak the bc to get hits @ 1350 yds?
Nope, base to ogive is totally different. COAL is around 2.820Do you have to load them long like the hybrids?
I shot these bullets today at a 100-800 meter range. It was factory ammo purchases from Southwest Ammo; COAL is 2.800. I got my data from Shooter; used .600 G1 BC, 2832 fps, 75 deg F, 55% rel hum (rough average for the time I was there), and 28.62 in Hg absolute pressure. Data was spot on all the way to 800 meters, requiring 6.3 mils of elevation at that range. I'm really leaning towards running these after I shoot up my 140 Hybrids.
What barel length ad brand of barrel are you shooting these from? Was your dope similar to your 140 Hybrids? better/worse? I figure they may even out. Lapua can be psuhed faster, with a .600 BC. Bergers are slower but have the BC advantage of .618. If they even out it would be a good indication the BC for the Lapua is infact .600 or very close to it.
Lapua has finally published the offical Bc's for the 136 scenar L. The published G1 B.C is .545 and the published G7 B.C. is .263.Not quite the estimated .600 G1. It is published on there website.
