Can someone please help me by sharing some load data with me? I ordered some 168 gr. VLD hunting Berger bullets awhile back and honestly had forgot I had ordered them until they came in the mail. Haha. I have a 7mm rem mag sendero that I really want to try them out in before a hunting trip out of town coming up in a couple of weeks. I don't have time to order a Berger reload book and get it to me before I go. The powders I have available are IMR 4831 & IMR 4350.
Could someone be so kind as to share start and max loads for these two powders ?
Thanks for the help MudRunner2005 but I don't have any H1000 powder on hand. IMR4350 & IMR4831 is all I have available and all will prob have available to load with before I leave for my trip. I plan on doing some shooting Saturday to check zero in my rifle. If I can find a load for the Bergers great. If not then I will use my tried and trusted nosler partitions
There are still quite a few guys using the powders you have also. I do not have much experience with them though.
I worked up a load this summer with 168's. I was .04 off the lands, 71gr H1000, Federal 215 match primers. I never chrono'd it, but I think it probably had plenty of performance. I wasn't getting a sticky bold or flattened primers at that point yet but I quit because it was shooting good and was plenty of snort.
I have a buddy shooting the 168's with 73gr Retumbo, obviously, like the 71gr H1000, you would need to work up to that in your gun. That would be a pretty woofy load I would guess also.
I am now going to try the 180's and see how it goes. My gun seems to be pretty receptive to hot loads so I think I will be able to probably be able to get some descent performance on the 180's even with my little ole 7RM lol Gonna have to wait for it to warm up before I get to play with that though.
Well here goes my 2 cents
I have been working on a load for my stock Rem 7mm for 9 months I am reloading all new 7mm Remington brass, CCI Magnum primers, with H1000 powder, Berger 168 vld hunting bullets in a 24 Inch barrel rifle......
The Load that I will be using is 69 grains H1000 with .30 jump averaging 2899 fps
this load seems to be the best one for my gun for good speed and great accuracy touching holes @ 200 yard Bullseye 5 shot group.
I did get a 3025 fps average load with 71.5 grains .30 jump but this load is all over the place about 2.5 inch groups @ 200yards. also ran 71,70.5,70,69.5. all not as accurate as 69.
I have ran all these loads with .20 .30 .40 thousandths jump and the .30 was the best in speed and accuracy for me.
69 at .30 2899fps 69 at .20 2866 avg. differences in speed just in the jump was a surprise to me,,, also surprising was hot loads 70.5 71 and 71.5 @ 200 were low about 2 to 2.5inches avg and the 69 is about 1/4 inch high go figure that 1 out I can't LOL.
Remember all guns shoot different!! If I were you I would do the same no matter how long it takes...
I am using a Huskemaw 5X20X50 zeroed @200yds 28 clicks at 600 yards this is what I get so far 900 yard shots coming next!!!
If You Think Its A Trophy Too You Than Shoot It!!!!!
Very nice. That is a good way of working up loads.
I have done it a little different to date. I load up a good mediocre charge, depending on the powder. I shoot 4 shot groups at different seating depths to find what works. Then I go back and load all at that seating depth, with graduating charges to find the best shooter.
One thing that a buddy of mine advised me on. He told me sometimes with these Bergers that you will be graduating charges and all of the sudden you will lose some accuracy. But if you keep going sometimes it actually starts to come back in. This was the case for me at 71 gr. I shot the best groups at 69gr and 71, then in between was different, some better, some worse. Not saying any way that anybody else does it is better or worse, just different. Just a few pointers that people with a lot more experience than me have passed on so I thought I would pass it on also.
