87 GR Berger VLDS, and H1000

[jmoney]

Hi there, I have an older VGX Vangaurd in 243, and I am pretty confident that it has a 1-10 twist.

Due to this I am restricted down to the 87 gr according to Berger, for their hunting VLDs. I got some load data from them, but it didn't have anything for the H1000 powder, and neither does the hogdon reloading site. I was wondering if anyone had worked up a good hunting load for their 243 using the 87 Gr in this powder, or if there is a good reason I should not be using it.

That's a little slow for lighter bullets in the 243 (and maybe even the heavier ones). You'll probably want to look at one of the 4350s or faster with the lighter bullets.

Have fun,
Brian

IMR 4350 was one of the ones in the load data, if you guys had to pick 4 powders to load up this round with, what would the other three be?

 

[outofayr]

H414 (aka Win 760), IMR 4320, RL17 should all get the job done.

thanks I think I have most of those so once my bullets get in I can whip up a nice load up for each of those powders and see what this old winchester likes!

Quiet lengthy but I enjoyed myself. Hope something here helps. JohnnyK.

Thanks for that information, I jotted it all down. Hopefully I will get the powders in and this stuff loaded up by next weekend so I can get out there and start playing around with it. I'm interested to see the difference in hunting with VLDs instead of the box ammo I have been using in this 243

Johnnyk.... That 46.5 grains of rl22 with a wlrm primer works like a charm.
I do not know what my grouping is but I hit everything I aim at. Thank you so much for posting that information. My savage barrel has seen better days but this load breaths new life into it.
