Re: Anyone notice this about Varget and IMR 4895?
Ok. Heres my .02.
I have no clue as to what barrel length or anything for that matter, that you are running so I'm going of what info has been provided.
IMR & H4895, & Varget are two different powders, with different burn rates - 4895 being the faster of the two.
In this case, I think velocity in a given node is the issue here.
I'm going to use MY rifle as an example.
26" Bartlein, 11.25 twist,
All loads using Lapua brass, CCI BR-2 primers, and Lapua 155 Scenars, and 175 SMKs.
For <span style="font-weight: bold">175 SMK's</span> with a target velocity of <span style="font-weight: bold">2725</span> fps I was rollin a flat 44 gr of Varget.
Switch to the <span style="font-weight: bold">Lap 155</span>, with a target velocity of 2940 fps, I was rollin 44.5 gr H4895
TO ACHIEVE THE SAME VELOCITIES USING VARGET, I ROLL <span style="text-decoration: underline"><span style="font-weight: bold">46.7</span></span> GR VARGET.
Notice how your groups tightened up as you creeped up to 43 gr Varget???? Velocity.
This is just my 0.02. YMMV
