    With the colaboartion of one of the wifes unlces, I built myself a .30 cal wildcat last year and never herd of the 7 LRM until today which I was reading about. Mine is .170" shorter to the shoulder and no belt, blown out case and a 30 degree shoulder. The original one was done on a .308 Norma case. However the .375 Ruger case seems to be the better easier way to go with slightly more capacity.

    I chamberd the gun last year shot a few rounds through it and kinda left it sit. Initial groups at 100 were extremely good with the first 3 shots sticking to 1/4". Case capacity over the standard norma case were about 3 grains H20 capacity. Have not had a chance to stick it over the chrony.

    After reading up about the 7 LRM I might have to break out my .30 again and start working with it again.

    I'm a big fan of the non-belted 30 degree mag cases.

    The photo shows the 7mm Rem Mag left, and my .30 cal wildcat Right.

    Search for elkaholic and his 30/375 s.i. kinda similar to what you have. I have a 7lrm and you can see my post with info on the particulars. Yours looks cool though.

    I think you meant that your case is on the right and the 375 Ruger is on the left?

    You are correct thanks. I have not tried to form out a. 375 ruger case yet and have been using the. 308 .Norma cases and turning the belts down. Then i can just load and shoot factory cases to fire form.

    have no loading data for the .375 Ruger, but the parent case looks like a .375 Steyer. Am I correct?

    Those pictures are nice to see. I thought for some reason that the body/shoulder junction on the 7mm LRM was pretty close to what the original 375 case was. I didn't realize it was bumped back that far.
