I was wondering what some of your guy's favorite loads are for the 300rum with the bergers. Group size, velocity etc...
Also any suggestions on what grain to use... I mainly hunt mule deer and elk.
If you are going to shoot a Berger out of a 300 RUM, I would suggest the 210. I am loading 95 gr of Retumbo behind the 210's and getting about 3200 fps. That is a "warm" load but not significantly stetching primer pockets. I would recommend starting at about 88 gr and working up. 93 gr is a typical max for the 300 RUM.
I have been loading 98.5 of Retumbo behind 190vlds. Out of my 28 inch Krieger they chronograph around 3450. My best 3 shot group is just over 2 inches at 500 yards. I have noticed higher than desired SD's with retumbo though. I have been in load development with the 210's, but have not been able test yet, so no data to share.
My 30" Shilen barrel loves the 210 ahead of 89g of RE25. Not sure of velocity but I've put together a few clover leafs @ 300yds and 1.5" @ 300 is common if I do my part. I'll have to look at my book to be sure but I think I'm running them with .01 jump.
I'm currently running 101.1gr of Hodgdon US869 under the 210 VLD and have groups running around 1.5" @ 300 yds. Velocity is right at 3,200 ft.sec from my 27" Broughton barrel. Pressure appears to be lower than any other powder I've tried.
E-Tips are monometals like TSX's, but they are a guilde metal, not pure copper. That makes them a little tougher. They also seem to expand a little wider than TSX's and they have a lot better BC than TSX/TTSX's. Last, I've read quite a few reports in the last tyear of TSX/TTSX's failing to expand. I haven't read that about the E-Tips, but they haven't been out long.
I recovered one from target practice the other day after penetrating 3/4 plywood them slamming into the dirt. It looks very impressive. It opend up to .665 x .588 and has a very flat, blunt frontal area which would cause a lot of tissue damage.
