Geco SP 105g

[jon15 14]

Have just been to my gun shop to buy some more .243 rounds and he quoted me the price for my usual 95g BT Federals and i nearly fell over, he said that he had some Geco SP 105g in .243 for nearly half the price of the Federals and that they we a good round. Has anyone shot them and what did they think, want them for deer and the odd fox. Thanks.

Hi Jon, if you have a look on the British stalking directory.co.uk you will find a few discussions on them.

Also just to note mate that the twist for your rifle needs to be 1 in 9 to stabilise the 105g at the very least.

 

if its a 1 in 10 they wont shoot well and you'll be wasting your money..

NOT SURE ABOUT TWISTS AND STUFF BUT I THINK YOU WILL FIND THAT THE GECO ARE MADE BY RWS IN GERMANY.

I HAD SOME IN 3006 AND THEY WERE FINE.

Good, accurate ammo but 105 grain is a little heavy for the .243 (twist dependant of course).

Not sure of my barrel twist, rifle is a Blaser R93, they only make one bullet weight so the guy in the shop said.

My Pro-hunter is a 1in12, which means shooting anything over grains is a bit hit and miss. 100 grain bullets will produce 2" groups. 58 grain V-max one hole groups.

Easiest way to measure your twist rate is to push a clean rod with a tight patch in to the chamber, with a permanent marker put a line on the rod at the back of the receiver and push the rod down the barrel until it makes one complete turn, make another line with the marker pen matching up with the same location on the receiver. Remove the rod and measure the gap between the two lines, this will give you your twist rate. For example if the two lines are spaced 8" apart, you have a 1 in 8 twist barrel, 12" apart you have a 1 in 12" twist rate.

hey mate, i'd nearly bet my life your R93 is of a standard 1 in 10 twist...... The 105's will not shoot too great with this twist,

Thank you, i did not know that.

No prob's mate, if you look at most boxs of ammo for the .243 in 105g they will state that you need a min of 1 in 9 twist....

Just zeroed my rifle with the Geco 105g in .243 and was really pleased with the way they shot through my blaser r93, 1" group at 100m, very happy, as was worried my rifle may not be able to stabalize the heavy bullets. Can not wait to go stalking. Happy hunting.

Just been stalking and shot my first Roe doe with them, dropped on the spot at 140yrds, very happy with them.

try shooting them at 200 yards to make sure they are not tumbling mate, or as the longer distance you go they may show the signs.....

 

100 yards isn't really effective for a test of stability.... As the bullet may only be yawing slightly and show no sign of keyholing..
