Hi guys,
I spent this last weekend playing around with my 7mm, trying to get a hotter load. I'm aiming for 3000fps from a 24" barrel tikka varmint.
I'm resonably green at re-loading so I have some ques.
I started with working up a load using ADI 2213sc (the powder I had recommended). The max load recommended is 64g. I got up to 64.5g, but I'm only getting 2800fps. I had no pressure signs, but I was worried about pushing it further.
I then borrowed a bottle of Vihtavuori N560 and worked up a load with that. I got significantly more muzzle blast, but I did get to 2930fps using 69g and had a nice .6" group.
All loads were loaded to Mag length 85mm and the there was still powder room inside.
Afterwards I found that V N560 and ADI 2213sc have the same burn rate??
My questions are
Do I keep pushing the ADI powder? I would like to use it as it is cheaper and easier to get. Also I am not a big fan of the muzzle blast I get with the V N560.
Would shortening the OAL lower the pressures and allow me to push further? I'm not getting any pressure signs as yet.
Should I try another powder ie ADI 2217? I have been told its a waste of time in a 24" barrel.
Thanks guys
