Absolutely!

Lots of hype on the Woodleigh Hydros. If Geoff would send me free packets of bullets as well, then I might write endless forums posts on them as well ...

As for the question of using a 7x57 on eg buffalo. In theory and in practice, there is no reason it will not be effective, 95% of the time, with careful shots and patience for the right shot and reasonable choice of projectiles. As evidence, look up the threads on Orion's hunt with me some years ago, 2005? when he proposed and did use his 6.5x54 MS on water buffalo. Two buffalo for three shots. At close range. I think he used a 140 gr Barnes X point, but I forget. And heart shots. The second bullet on the first animal was because the PH insisted. On the second buffalo he refused to shoot a second time. And after walking some steps it fell over dead.

Now as one of NE's other members informed me, when asked why he no longer used his 6.5 MS on buffalo, as suspected he said when things go wrong, the rifle is not a good choice .. and uses his .400 NE now usually instead. Or similar choices.

A 7x57 with a good 175 gr FMJ would be a better choice than a 140 gr Hyped up Hydro IMO. Just what I would choose if going this route.

For everything else, I see zero reasons for using a hydro and would always use a good 140 gr, 150 gr, 160 gr or 175 gr SP or FMJ instead.

But again if Geoff sent me packets of freebies for the endless hydro forum articles, maybe I could write glowing stories about them as well ... when the sun shines out of the ends of the apertures of the muzzles ... and a bullet which does not expand through a 'magical bubble' makes a wound channel wider than a SP which holds together and doubles its calibre or more, or over penetrates a FMJ which holds together without expansion ...

I think I do have a packet or three, I purchased years ago. Might even try them one day ...

But at $4 a bullet, they would have to be made of gold !!!!

Would like to see the science/physics of the 'bubble' explained one day as well.
