Re: New savage LRP 243 owner need load advise
So, first thing to realize is that you cannot buy the superformance powder that is in the Hornady 95gr ammo. I have 8lb of superformance powder in the reloading room and it is not the same thing...
However, you can buy 95gr SST bullets. I have been loading with Hodgdon H100V powder and so far I have been very happy with it. Right now I can tell you that you will not get 95 or 105gr bergers to group out the factory barrel, since it cannot stabilize them. In the factory barrel, the 95gr SST or possibly an A max is going to be as heavy and as high a BC as you will get.
I replaced my barrel with a 1:8 twist Shilen match barrel and I can now shoot the 95 and 105gr Bergers just fine. My chamber is now an ackley improved so I fireform with the 95gr Berger and then load 105gr VLD's in the fireformed cases.
For whatever reason with the 243 the ball powders seem to dominate. Highest velocity is a 3 way tie to Win 780, 760 and Hodgdon H414. The Hybrid H100V is right on their heels. So far it has shot very consistent for me and it was more readily available in stores than most of the other powders. I am using regular CCI 200 primers, since I could never find any magnum primers.
