Re: Reloading the Berger 230 Match Hybrid Target
I use the Hornady New Dimension or Custom grade dies, they have a sleeve inside that holds the bullet straight while it seats it in the case.
If you try to use the maximum velocity load and try to tune it for accuracy you are going to pull your hair out or burn your barrel out.
You will need to load up some rounds in 1/2 grain increments till the bolt handle just gets a little hard to open then drop back 2 grains and that is your max load. Then load 3 rounds at 1/2 grain increments to your new found max and take it out and shoot it at 300 yrds. ( When I was working up loads for my 338 Ultra mag they didn't group good at 100 yrds, then I found out that the longer bullets don't start to go to sleep, or stabilize to past 200 yrds ) then they will group better. Find your best 2 groups and go from there, by adjusting seating depth or powder charges just a little.
Sizing will depend if your once fired cases will chamber back in your rifle, then you could just size them till you resize about a 1/4 inch of the neck.
Good luck and keep us informed.
