anyone using the 120gmx?

I recently bought some 120 gmx before reading about this.. how can i go about cuttin them down.. 18in barrel lookin to take 300 yard shot a deer or hog

You will need a lathe of some type, with zero runout. Bullet has to be kept cool, otherwise plastic tip will overheat , and ooze out. Good luck on your quest.

I just got a box of 140 GMX, to cut down. 100-102 gr. is the goal. It's the international version- designed for scandanavian moose hunting in short range . Tip is flat, it's designed to open at lower speeds.

We'll see.

Welcome aboard spoon!

ricsmall - couple years ago I sent him Gmx in 105 trim, he dropped a deer @ 325 yds with it.

I kill a lot of Hogs and out of the Grendel the 120gr Soft Point is just not fast enough to put them down. I used 27grs H335 and only got 2200fps which in my opinion was too slow for the bullet to perform. I am now using 100gr Sierra Varminters with 29gr H335 and I am getting 2500fps. Mind you this is actual speed from an 18" barrel not the 24" that most of these Factories use to test their bullets. These 100gr bullets seem to work real well but I think penetration is lacking for really big hogs. On a Deer they should slam them pretty good.

Sweet thanks for info i also have 18". I only have cfe223 and leverevolution. Just got some 100gr tac tx some cavity back 118gr and the 120 gmx. Most shots are around 50yards but on accasion deer cross around 325 yards and want to be able to take those shot most shots at 50. ards are all hogs.

I got interrupted when posting the above post. I noticed on the big Hogs 250+ that they would go down but a lot were getting up to run off. It was even worse with the little Hogs. This was tested on several hundred Hogs that were shot in actual hunting conditions and Ear Hole shots were not considered. I tried the 120s to find that when they fell they stayed down but the bullet was just not delivering the shock it needed. A lot were pass through. Since getting Chronograph, I found that most of the Factories are giving FPS values that are in 24" barrels and actual speeds were right at about 200fps slower than advertised out of an 18" barrel with a good safe reload. Best results were obtained in all situations with the 100gr Varminters by Sierra.
