Just put together a few new loads and hope to get out soon. 130gr BT H4831 Nosler brass Fed 210M 130gr Berger Classic Hunter H4831 Nosler brass Fed 210M

You got that right. Scary accurate these rifles lol

150 PT 53grs H4831sc Nosler brass WLR 3.320" Another good load, but probably a bit slower.

Didn't run it over the chrono DrMike. Going to load up some more and play with seating depth and chrono them.

Initial load looks promising 130 PT 59grs H4831sc Nosler brass WLR 3.320"

RCBS universal priming tool for me.

I am using 3.320"

Just loaded up some using H4831sc and 130, 140 and 150 PT Might as well try each lol

Exactly. It just plain works.

Many thanks! I am going to start with H4831 and see how things go. Picked up some new Nosler brass as well.

Could someone please run QL on the following bullets? 130gr AB 130gr BT Thanks!

Darkhorse: That's what I'm thinking as well. Seating depth is the key. I have a Hornady OAL tool, but have to pick up a 7RM case.

I would like to try RL22 but it's difficult to find up here. RL23 is easier to get. Oh, and I got some 140 & 160 AB as well as 160 PT to try. Sent from my iPad using Tapatalk

Just an update... Tried H1000 with the 140gr TTSX COL 3.230" W-W case WLRM

Just curious. Who makes the brass? I was thinking Norma.

Just picked one of these up and pretty neat.

Thank you DrMike!

Could someone please run optimum powders for 7mm RM and the 160 AB and 160 TSX and 140 TTSX? :grin:

I ran into similar issues with a batch of H4831 when loading for a 270 Win. Velocity was 100-150fps below book numbers. Same barrel length too.

I took those loads directly from the Barnes manual. It listed 63grs as max, so that's why I stopped there. Didn't have any ejection issues. Going to try some 160 AB and see how they perform. Been close to 30yrs since loading for the 7RM. Last powder I used was H870 and Hornady 162 BTSP lol
