I should have put in a bit more background in the original post, I am a probationary member of the Conservation and Wildlife Management Group in SA. The primary use for the 120grn Hornday VMax will be for culling goats.

Thanks Big Pete, I was looking at that but I was concerned about the difference a flat bottom vs a boat tail would have on the load.

hornady case, rem 9 1/2 primer ,start load 36.5gn - max load 43.7gn @2.7" col .
Thanks Big Rich this is exactly what I needed to get started with the 120grn load.
bigrich wrote: had no luck with 140sst hornady's due to mag length . order yourself a "M+" tikka magazine , they make these in 3" col for the 6.5 manbun . being limited to 2.8" col limits what you can do with heavier projectiles and case capacity in 7-08, and tikkas have a long free bore to the lands. hope this helps , cheers
I have already bought a "M+" tikka magazine and was attempting to load Hornady 139grn SST. I am down to a 0.7" group but this is not consistent and is not any better than what I am getting with the Hornady Factory Whitetail ammunition. Which is half of the reason I am stopping this load development and trying a different projectile.

This is very interesting and gives me another option to look at. I have done a quick search on line but could only find the flat bottom Hot Cor not the boat tail. If I am putting the effort into handloading I want a very accurate round when I am finished.

He had some difficulty getting decent groups on 140gn and 120gn projectiles.
Recipe that I've been using ever since is same as he'd worked up for the 120gn BT projectiles:-
Thanks Jorlcrin, if I cannot get the Hornady 120grn VMax to work I will switch to Nosler Ballistic Tips. It is just the price and availability that is the problem. Hornady is half the price of the Nosler projectile and this ammo will be used for culling goats.

I was having trouble with the recoil on this rifle as it has a light scope on it also, so I did a stablising, pillar and bedding job to add about 200gms. This has reduced the recoil and made it much easier to shoot. No sore shoulder the next day makes a big difference.

Again; didnt really try to get them much tighter, but likely could have.
The 100gn HP Sierra Varminter projectiles are another projectile I am looking at for culling goats. Good price but not sure about availablity.

Thanks Billo, it looks like most people are getting the loads to work at the top end of the range. I will work up to it slowly, but gives me an idea of the sweet spot will be.
Thanks All, Late Starter.
