Thread: 7mm RM 162 Amax

Thanks for all the replies. The squares are 25mm/ 1" so not that small. And at 100 yards.

The towel just helps when firing off 20-25 rounds in one sitting. But no don't generally hunting with a towel on my shoulder. But do generally wear a base, mid and top layer so comes close considering it is a tad warm and just in a t shirt.

The photo of the projectile next to the case is touching the lands. At the moment they are seat 10mm deeper than that. Was saying I could probably seat it out 5-5.5mm more and still have at least 7mm in the neck.

Most of the groups would have been 5 shots. But the others got sent slightly off target towards something else.

So far the loads that were supplied have been quite consistent (when I do my part) at hitting an A4 gong at 500. But think I fluked a very small group with them and can't replicate it loading how he did. So just wanted to see if I could make it better.

Cheers again for the replies. Will try a couple different loads around 71.5 plus just a couple higher to check.

Can only guess where your 10mm deeper seating would be but I would seat for a starting point, in your case, so that the point on the projectile where it changes from the boatail section to the parallel shank lines up with the shoulder neck junction on the case. Assuming your powder charge is not being compressed by this seating depth - it shouldn't be. With your long throat I wouldn't even bother chasing the lands. I have a 22/250 that I cannot get within cooey of the lands and it shoots exceptionally well still. A cartridge loaded as shown in your photo with the projectile so far out, if dropped on the floor, would develop a severe case of runout/wobbles. When dropped they always land on the projectile end of course. Also consider when developing a seating depth the max mag length limitation.
