Geco Zero bullets 127gr 7mm

[the_greenman]

Has anybody reloaded using the above.

I've been using 140gr Rem CoreLokt factory stuff in my 7mm08 but am feeling the bullets are not suited to the likes of roe and muntjac as they appear to have pencilled through on a few causing long follow ups and sometimes 2nd shots. On checking the carcass, I'll find fairly neat holes through heart and lung which makes me think they're too hard for the smaller deer.
I saw the above and thought I'd give them a try as they appear to be designed for smaller European game. Any thoughts? TIA

Used them in 7x57 and they were so destructive on roe with chest shots I moved away very swiftly indeed

Was that down to their fragmenting design or the speed they were being pushed at or both? I use fox in my 6.5 and am impressed by them but the Geco bullets were much cheaper so thought I'd try them

Simply due to the fragmenting design; they act more like varminting bullets on deer

Took a chance and bought a box to give them a go. Does anyone out there have a recipe for them?? I have RL16/17 and H4350/4895. Leaning towards the H4350 but if anyone has a load in any of the others I'd be just as happy. Rem RP cases, Rem 91/2 lr primers. Can't find any data online for them which is a pain.

If you are looking for a non lead bullet in 7mm I have always found the 120gr Barnes TTSX to work very well. My only experience with the Geco Zero was a good friend using them in 30/06. Killed hinds well and damn near decapitated roe with neck shots. I have also had similar experiences with Remington Core lock in 30 calibre

Thanks. I have some barnes and some fox (which I have had very good results with in 6.5) but wanted to see how these perform too.

I tried Geco zero in my 308 and found them too frangible for my liking

I have been working on a load for them out of my Tikka and managed to get 3 rounds touching at 100m so accuracy is ok. I went out yesterday and neck shot a roe buck (only because it's all he presented) so no real test of their explosiveness but later on I shot an old almost prehistoric looking munty buck. Antlers right down to the pedicles, one tusk and a neck probably as thick as the roe bucks. It was a heart shot at 60m. He made 10m into a wood and the blood trail was perfect. Opening the chest revealed a tiny piece of heart left. The rest was soup. There were 2 exits holes. One slightly larger than the entry and a 2nd that was probably from a petal. I haven't found any other damage apart from ribs yet but will have a closer look today. I'm hoping that keeping the load at the minimum end of the data (providing accuracy is ok) and my Tikka only being a 20" barrel might reduce the speed enough for it not to go off like a grenade. Early days for results.

Sika I butchered couple years back- shot with fairly slow 127gr 7-08 I believe. Good bullet performance.

Yep. Broke the munty up today. Not as much bruising in relation to carcass size but I did find half a dozen copper shards scattered about in the shredded meat. Excellent lead free bullet for fox, or head/neck shots but I think I'll use up what I have left and start on the Fox bullets I got off Edinburgh Rifles. Had good results in 6.5, so will expect same. Shame as the Geco were half the cost of any others.

For what it's worth, I started out in copper with (factory) Geco Zero and was happy with them as not much to compare with. They are certainly lethal and the pre-fragmented tin front section surely fragments and the rear section always powers through to leave good exit on everything including fallow bucks (not tried on red yet).

Meat damage is variable. Muntjac shot through a shoulder can almost remove opposite leg. Muntjac shot behind shoulder through ribs isn't necessarily any worse than monolithic copper. As has been said - with neck and head shots the fragmentation is a benefit. I have since shot monolithic Nosler E tips in the .308 and also Hornady CX outfitter in the 6.5CM.

While I probably favour the Hornady CX in 6.5, it has to be said that meat damage is really variable across the board - two outcomes are rarely the same. Last week I shot a munty buck at about 40m with the Geco Zero .308 - placement behind the shoulder and 'visible' exit wasn't any bigger than a monolithic, although once skinned there were three very small fragment exits around the main exit hole. Meat damage was no worse than either Outfitter CX or Etip.

I have actually just stocked up with Geco Zero as, by and large, I think, with lethality/accuracy/meat damage all taken in to consideration, they are a good round and suit my rifle. If Hornady Outfitter were the same price, I'd probably swing over to those in .308 providing they were equally accurate in my rifle.

I haven't tried the CX yet (bought some for the .243). In the 6.5 I've found Fox so far have given extremely good accuracy and removing the black tip gives a resounding "whop". Lehigh Defense Copper Chaos gave good knockdown results on big fallow too but a friend found a petal in a haunch (from a side on chest shot).
I only decided to try the Geco due to the price but leaving tiny shards in the meat isn't something I want. If its not for me then my dogs get what's left and a vet's trip is undesirable. If the fragmentation was minimal ie 3 large petals then I'd manage but the Geco were tiny and about 6 (found) pieces scattered throughout the meat of the shoulder.
Geco also have the Star bullet but I don't think it's available in anything yet except .308 and 8mm. It looks like a better option so I'll write to them and see if they intend expanding their line.

This translates reasonably well.....
