I recently bought a Savage BA 10 Stealth in 6.5 Creedmoor and have started my load development. I know that H4350 is "THE" powder for 6.5 CM but finding it is another problem. I happen to have a very good supply of VV N160 so decided to try and work up a good load using it and see what happens. There is not a lot of data floating around for this powder but VV lists some data for 139 gr and 140 gr bullets and I had previously requested a QL run for this using 140 gr Nosler RDF bullets, so I have had some good guidelines to start with. I am in a long range shooting club where we are working our way to 1000 yards. This load will be for target shooting only. I have been shooting a nice 308 Tikka T3 Tac and done very well out to 600 yards, but trying it at 800 yds on a windy day was a humbling experience. Hence the purchase of the 6.5 CM, hoping to significantly better the wind bucking ability at 1000 yds. I am using my local range for load development which only has a 100 yd range. My target velocity is 2700 fps. Hornady 140 gr ELDM's shoot at 2695 fps in my rifle. Using a Hornady comparator, Bullet to lands length touching is 2.876", which happens to also be max mag length. Book length is 2.825" so I started with this. Using CCI BR-2 primers and new Hornady cases. Using 3 shot groups. So far am seeing some promising results as follows:

41.0 gr 2512 fps .775"

42.0 gr 2565 fps .475"

43.0 gr 2607 fps .960"

44.0 gr 2680 fps 1.725"

44.5 gr 2695 fps 2.265"

45.0 gr 2725 fps .740"

As you can see, 42.0 gave the best single group but velocity was low. 45.0 gr gave the velocity I wanted with a decent group. 44.0 and 44.5 were 2 touching , 1 out (way out!). Conventional reloading wisdom says that I have room to seat out longer and probably tighten up the groups. So I loaded 44.0, 44.5 and 45.0 gr at 2.856" (touching minus .020"). All groups were in the 1.5" range including the 45.0 gr load. So now I intend to go the other direction, loading the 45.0 gr load at 2.805 and 2.825" to hopefully repeat my earlier group of .740" and see if deeper seating helps tighten up the groups. Will hopefully shoot those loads today or tomorrow.

I would like some advice from our board:

1) since I am using a 100 yd range only, is there any value in trying the OCW method? Most sources say shoot OCW at 200-300 yds.

2) for target use at 800-1000 yds only, assuming no other improvements are found, would you opt for the tighter groups at 42.0 gr (2565 fps, .475") or the greater velocity at 45.0 grs (2725 fps, .740") ?

3) any other suggestions?

Thanks,
