drop you a federal 210 in there and see if that want cut that group in half. I worked a load with new norma brass using a fed210, imr 4831. 55 gr. ,2930 fps was the sweet spot. As usual . Es was 14 fps, sd 7 fps. Shot .3 or less. The bullet is a sierra gameking SBT130gr. Sweet load. 1300fps at a 1000 yrds. Shoots tighter than a tick on a dog! The norma brass has to much volume for the h1000. Cant hit the sweet spot without being right at book max. I dont like to run that close to max. Works good with rem and frontier brass. 1 gr. Off max is usually gonna give you the tightest groupings. I never had any luck past that.The wind finally laid down enough to shoot.
Found a load of 63 gr/H1000/200CCI primer/130gr. Speer boat tail/Molyed in a new Win. case that I neck sized to .004 under shot an average 2990 fps into a 3/4" raged hole @ 100 yds.
Tried a Magnum/250CCI in all compression loads, gained an average 30fps on all loads with the accuracy staying same until I went over 63 gr. with either primer the groups opened to 5" so I unloaded the hotter loads. No sign of over pressure on any load as far as I went. Anything over 3000fps was not accurate and the quicker it went the worse it got.
Need to try neck sized fired cases and play again. It's been raining now for two days but I'll take that over the wind.
Thanks again for all the advise.
I'm aware this is an old dead thread, but I wanted to throw In here just in case someone comes looking. I load 140 gr hornady interlock sp and sometimes sst over 62.5 gr of h1000. Averages about 2800 fps. My rifle shoots ragged holes with this load. I tried it out of desperation and stumbled on something good. 63 is compressed so yes the case is full.Hey high cotton, Did you get any useful information on using h1000 in your 270? I like a full case!
