I have tried to get the Hornady 75gr BTHP to play along with my MR223 but all my efforts have been futile.
So far my attempts have consisted of
Materials:
2 cases, Sako and Geco.
3 primers, 450, 400 and Ginex
Only N540 powder, I have settled to that and have it stacked.
Reloading changes:
Powder charges of 23.9, 24.4, 24.7, 25.0 and 25.2.
COALs of 2.230, 2.250 and 2.26.
I am now waiting to get to the range to test my latest reloads with 25.2gr and COAL of 2.271, 2.286, 2.296 and 2.305.
Obviously this is grabbing on straws since 3 of 4 of above load lengths are over any mag length.
I did notice that my barrel is shot enough that I cannot reach the lands anymore, after trying with shorter lengths I carefully fed a crimped case with a bullet seated at 2.559 and it returned with length of 2.551 without any marks.
My scenar 77gr loads are still hammering without any problems and even PMC and Geco bulk do better than my handloads with the 75gr.
Is my barrel so shot that I cannot get the Hornadys to run with it anymore? Just surprising how the contrast between scenars and them is so stark. I switched to 75s because one distributor got tons of them while scenars are hard to find and cost 43% more.
The scenars do nearly 1moa while hornady does around 2moa. Bulk is between with 1.4-1.6moa.
So far the SMALLEST group of 14 groups with hornadys has been 1.5moa.
I am waiting for a spare barrel to arrive but it might take some time and have not seen any reason to replace it just yet.
