Hello to the collective ...
I have worked up loads for my Sako 85 in .243 using H414.
I have used 70 grain nosler ballistic tips, 80s and 90s.
All have ended up at half a grain away from the max loads stated in the Lee manual to achieve the best accuracy. getting 1/2 inch groups.
The thing is all the loads are flattening the primers, but there are no other signs of pressure, no heavy bolt lift and cases all look fine.
Is this ok.??? The left hand one is the flat primer , the one on the right is a light load for comparrison...
Also i have worked up my 100 grain loads and have come to 39.5 grains of H414, which is half a grain away from max, and havent got close to an accurate load yet, no signs of pressure yet, so i suppose i carry on and see how good they get?
Thanks for looking.
