That's funny Mudrunner. Here three of us are typing away with all sorts of details and we missed an important one ourselves. He could have worn the barrel out or sold it by now !

After I typed that, I almost left "He's probably either got it figured out or sold it by now..." But I decided to edit that out. Figured some of the more "PC" members might get their panties in a wad. LOL

Being a 7RUM, good chances are he's probably worn 2 barrels out by now. LMFAO!

I should have, but I try to help them spare the emabrrassement, mainly because I've done it myself.

Re: help 7mm RUM sendero no accuracy

Good evening. I have a Rem 700 Sendero also in 7 mag. I shoot the 168grn Berger VLD with no complaints. I have done nothin to it but put a scope on it. It has a Tasco SS from SWFA. It's just the fixed 10 power model so that hurts accuracy. I can't see the bullseye. I just line the cross hairs in the scope on the paper and I can get a 5 shot group just over 1/2". Not quit .75" group but just over .5" group. I use 72grns of Retumbo powder. Now this is a hot load so be careful!!! Berger Reloading Manual says Max Load is 71.2. But that is for standered length. Which is ( COAL - 3.290" )Deep in the casing. I'm seating mine long. Deep in lands. So the pressure changes allowing me to use more powder without raising my pressure.( How I worked up my load. )I started with 66grns and worked my way up to 72grns at 1/2 grain intervals. Here is my loads. 66grn- 66.5grn-67grn-67.5grn-68grn-68.5grn-69grn-69.5grn-70grn-70.5grn-71grn-71.5grn-72grn-72.5grn-73grn-73.5grn. I stopped there cause it started show pressure signs. Now here is a great test to see what load is more accurate for you. Sight the rifle at 300yrds with some bullets you all ready have done. Then with the data I just gave you for your new reloads. Shoot each bullet at the bullseye without making any adjustments. But every time you shoot don't forget to right down on the target what grn powder was shot. Do this to every bullet. There should be a pattern with a few bullets in the same Vacinity. Some will be way high others way low. Don't worry about if you hit the bullseye just the bullets that are really close to each other. Pick the 2 or 3 loads that are closest and load 5 rounds each and see which one groups better at 100yrds. That will give you an accurate load. Sorry so long!!!! Hope this helps. It's worked with every gun I own. More than 1.

You must have a rem mag? For a hot load with 71grns?
