I intend loading my 7x57 with GS 130gr bullets at around 2900fps. Hoping to use one load for springbuck at long range and kudu at short to medium ranges. Has anyone any feedback regarding terminal performance with this bullet on these game animals, including distance,accuracy and penetration? Many thanks.

havent used that one but if your refering to grand slams ive used alot of the 145s in the 280 and 7mag and theyve allwasy preformed great for me. Its one of my favorite bullets in the 7s

I've had pretty good results from 145 gr. Grand Slams in my 7mm-08 on mule deer and elk.

lal are you referring to Grand Slams or GS Customs? If the latter, then Gerard should be able to help you.

I think you are talking gs customs. If so they are great killers. I have not shot in my 7x57 yet but 375 and 404 both were awesome.I don't have the 130hv's but the 120's are your bullets .284 or .285

Thanks for all the replies. I am referring to GS Custom Monolithic bullets.

I load the 120gn GS Custom HP's to 3235fps with BL-C2 and Fed 215's in my 25in bbl 7x57 with excellent accuracy. The GS was the easiest bullet I have ever worked with to find a load for and while a goat isn't the hardiest animal to try them on I did take 5 with them last week out to 253yds for first animal trials. Will take them on a new deer block when the permit comes in soon.

Von Gruff, thank you. That,s the kind of answer I am looking for.

Von Gruff, glad to see another NZ shooter using the GS Customs. I was using the 120gr also in my .280 Remington Mountain Rifle with excellent results, getting 3250 (22 inch barrel) using Winchester 760. Then when I had my .270 I used the 110gr at 3450fps. I'm currently thinking about a custom 7mm WSM with either the 120 or 116's.

Cheers,

Michael.

If you go with the new 116 it has a BC increase from 390 for the 120 up to 468 for the 116 going by Martins new GS website and would be of advantage in a 7mm wsm. The 120 offers all that I could use in my 7x57. Got my permit notification yesterday and will have the 28-29 May so hope to trial them on a big Red. Hopefully still dry weather but wallowing could give the bullet a bit of mud to get through.
