Re: 7 mm lrm

So what would the ideal case capacity range be for a high-performance 7mm be? Grains of H2O.

My #'s are likely not super accurate, just flipping through some various manuals and looking online for #'s. Just trying to put the cases in order and see if anybody can chime in to what the ideal case is.

280 Rem AI ~65 grains H2O
7wsm ~73 grains H2O
7 rem mag ~78 grains H2O
7-300 win mag ~81 grains H2O
7 LRM ~88 grains H2O
7mm Dakota ~89 Grains H2O
7 stw ~92 grains H2O
284/26 Nosler ~97 grains H2O
7mm RUM ~105 grains H2O

What others would you add? It would look to me that the range people use the most for LR rifles would fall somewhere between the WSM and the STW. Looks like the LRM falls right into the sweet spot on the higher end of things. Again, I'm sure my #'s could be adjusted, please feel free to correct them.

Then the factors such as belt/beltless, shoulder angle, overall length, etc come in to play to design the rifle. So many things to consider, it can get overwhelming to try and make a decision.

Re: 7 mm lrm

For obvious reasons I vote 7LRM. I have had nothing but incredible results with my setup.

Re: 7 mm lrm

I like the design of the LRM, but the brass sucks. It is the softest brass I ever worked with. I wont do another until somebody else offers decent brass.

Re: 7 mm lrm

Could build a 7-26 nosler and be a beltless STW (26 Nosler holds 93 grains H20). That way you could throat the chamber out to seat long bullets further out to optimize case capacity and still be a repeater. Just saying.
