I was shooting 39.5 grns of Varget with a Hornady 200 gr bullet out of my Rem 760 (made 1980) with exceptional accuracy. I was able to get 2100 out of it. I love that rifle and just two weeks ago I found it a perfect mate.....a Marlin 336D Guide Gun in 35 Rem. Apparently only 1000 were made for Davidsons (a distributor). I have yet to shoot it but I am thinking of trying the Speer FP. Good luck with your +P loads!
