[QUOTE="Ragnarnar, post: 1270239, member: 98218"] I've got a 7LRM build in the works. I'll share some of my decision process. I knew I wanted a 7mm to sling heavy bullets way out there. Specifically the 180 Berger at around 3100 FPS, but I also wanted to be able to play with the 195 as well. I reload. So no restrictions on cartridge based on availability of factory loads. Because OP is asking about the case I'm going to ASSume you do as well. Then I looked at case capacity as a measure for power. And because I didn't want to deal with belts, I discarded those, which rules out the RM, WBY and STW. This is from another thread here about two years back. I think this is mudrunners list 7mm BR 7-08 Remington 284 Winchester 280 Remington 280 Ackley Improved 7mm RSAUM 7mm WSM [COLOR="red"]7mm Rem Mag 7mm Weatherby[/COLOR] 7mm LRM [COLOR="red"]7mm STW [/COLOR]28-Nosler 7mm RUM Then I examined the remaining options. According to my reloading books and what I could find online the RSAUM and WSM were pushing 175 LRAB around 2800fps at a maximum, which is respectable, but because I wanted to shoot 180's and 195's they would be just slightly anemic. If you look online you'll find people pushing them harder but, I don't really care to do that with my reloads. This left me the Nosler, the LRM and the RUM. The rifle is intended to be a backpack hunting rifle, so I wanted to keep the weight down. Not that any cartridge remaining would kick any less, but shooting a RUM out of a ten pound rifle doesn't sound fun. Call me a wimp if you want. Also I've heard less than positive things about component life in RUMs So now I'm left with LRM and Nosler. I went with the LRM because of what I perceive to be the better case design and the reported efficiency of the chambering. Thats just my opinion. Good luck [/QUOTE]
