@Sidney said this on page 1 about the GS custom...
Other than turned copper they are quite different. The GS Custom projectile are fitted to the lands diameter with extended bands to fill out the grooves providing the seal. This reduces friction and pressure allowing increased velocity for the same pressure.
These look more akin to most conventional copper pills with recess grooves to reduce friction on a projection turned to barrel groove diameter. More grooves cut though than say a Barnes/GMX.
And...
The diameter contact land to land is critical with the GS custom. If you don't get that right they are hard to get to shoot well. The barrel specs vary marginally with different manufacturers and GS Custom produce projectiles to suit.
Essentially a custom projectile. They shoot well when all the variations are sorted, if you can be bothered. I played with them and they worked well, but they tend to not like being interchanged with other pills and that didn't suit my budget.
so if you see a deer walking slowly across a field and shoot it with one of these bullets you can actually yell " stop...yeah....hammertime"

No pressure signs so could drive them a bit harder but want to be kind on the brass as I only have 50 sticks
Tested out the hammers today.
This first on is a yearling red at 240 yards, shoulder shot.
Dropped it on the spot
Exit wound
Attachment 168232
Not a huge amount of damage to heart and lungs
Attachment 168233
The hammer did enough damage to be happy with it

The next was a hind at 342 yards, lower neck shot.

She was still kicking around when I got there. I think this shows that like all monolithic coppers the hammer needs more resistance on impact. There is less margin for error compared to a fully frangable lead core projectile but it is nice to know that I am not feeding the family lead burgers.
In general I am happy enough with its performance to keep testing it out. I would imagine a big bodied stag would feel the wrath of the hammer in a big way. Would probably be a great Roar load
Great solid copper projectiles are the way forward :)
Pretty hard for one bullet to do everything though
You are back on @Kiwi Greg I have missed your imput
Looking at the drop chart its a pretty sweet load with the 10 power scope with a couple of hold over points out to 500 yards. Makes for a real handy point and shoot all round rifle
