sitsinhedges Posted December 25, 2010 Report Share Posted December 25, 2010 Thinking about trying some of this powder, mainly because it seems about as cheap as you are likely to get at £32/kilo. I can see 24-32gram recipes for 12gauge and also 24/28gram ones for 20gauge so was wondering if anyone had used it and what it was like compared to the Vectans that I am currently reloading with. I understand it's a powder rather than a flake and wonder if that means a whole new set of bushes would be needed etc. Loved the AS24 that I just had but can't get anymore of that for light loads unfortunately but this GM3 seems very versatile at first glance. Any thoughts Quote Link to comment Share on other sites More sharing options...
onlyme Posted December 25, 2010 Report Share Posted December 25, 2010 Hey pal the GM.3 is a good cheap powder and I've used it a lot in 12 g for loads between 28 and 32 gram. Worked a treat and is very good value for money can't recommend this stuff enough.... Got all the load data here pal for you my own and the book data which is very good. It's super versatile and I think with good primer choice you could load it nicely for 20g Quote Link to comment Share on other sites More sharing options...
cuffy Posted January 4, 2011 Report Share Posted January 4, 2011 i have been using gm3 for a couple of months now 28/7.5s and 32/6s every thing seems to be ok having said that i am new to this reloading malarky . Quote Link to comment Share on other sites More sharing options...
MC Posted January 5, 2011 Report Share Posted January 5, 2011 GM3 is my favourite powder, it is fast clean and smooth. I use 21grains of it with an ounce of shot and either plastic or fibre wads. This gives me a very smooth and hard hitting cartridge. Please let me know where you can get it for £33 a kilo? Quote Link to comment Share on other sites More sharing options...
