Push for more speed?

[Steve Blair]

Well I took your advice! I'm now shooting 140 VLD's at about 2800 fps. Haven't tried it at 1000 yet but short range results look promising. I've taken a lot of notes from your posts. Thank you.

If they are tuned properly, you will be amazed how much easier it will be with the. 140's vs. the 105's. Problem is, you will start thinking "What if I had 180's?"

Some even wonder about 230's.

Erik I thank you for the opportunity to learn more about going in the right direction. I never stop learning on this site. I have one question, is there any other powder more conducive to better accuracy at long range than varget. Again this is just a question as I don't know what powders are the very best for this application.

Different powders will behave differently with different cartridges, barrel lengths, and even primers. I don't think there is "one" best powder, I think we should try different powders with same similar burn rates that would work in our intended application and test them all.

This often overlooked due to what most believe should work. I shoot 30.6 of Varget in my 27" Broughton barrel at 2850 fps. I heard from everyone that CCI 450 were the primer to use and was advised against using anything but. Mine shot good with them but when all was said and done BR-4's got rid of the vertical and sucked the groups in even more. As stated you want to be in the middle of the sweet spot not on the edge.

I was told the same by many for my 6.5x47,,CCI450 and nothing else,,I tried some WW WSR with 42.7 grs H4350 and get 2965 with 123 Scenar and SD was ONE!!
shot 300 yard eggs last Sunday and hit 10 in a row,,,and was shooting 2.5-3 inch groups at 800 on average and had one that was 1.5 inches,,

Fellas,

Currently doing load work for a 6br I built. Barrel is an 8 twist .237 bore Bartlein in Remington varmint countour crowned at 26 inches.

I have a load that is showing promise at 550yds.

105 VLD
30.6 grains of Varget
Rem brass
CCI 450

According to my drop, this load is running 2810fps. 2 tenths more Varget caused serious vertical at 550. I've seen nothing to lead me to think I'm at max, but it's certainly not a mild load.

I've always used the 6br as a midrange varmint round with 55 and 70 grain bullets. This is my first go with the 105's. I'm inclined to sit at 30.6 grains instead of looking for the next node up. What say you??

Thanks,
John

RL 17 Winchester 760 N550 all will pick your speed up With 105. Larry

Push for more speed? why .2810 fps is about it for 26 inch .237 bore. I would not be using CCI450. My best load for a BR, 105VLD, .237 bore is 29.8-30.3 RL15,Br4,touch to .002 jump. If you want more speed from a BR, a 30" barrel with .236 bore. Or Improved BR.

You might give N540 with the 450s if you want to try to get up to the next node. It was the very best combination in my 6BR with 105 VLDs.
