Add the 7 GNR to your list. It is based on the 30-30 case.

the 7GNR i JUST SAW A RIGHT UP on that ,its gary reeder custom guns- so i guest all of those are on the 30-30 case but what about the 7mm bullberry

All of Fred's proprietory chamberings, "Bullberry", are based on the 30-30 case, so some of the above is a bit confusing.    He doesn't offer a 7X30 Bullberry as per se, but he does standard 7X30 Waters and a 7X30 Waters Improved's.   So, his 7mm Bullberry would just be his version of an improved 7X30 Waters, and I'll guess it differs from a "standard" 7X30 Waters Imp by having a different shoulder/taper.   He was cambering for the 7mm Bullberry a long time before he added the 7X30 WI to his list of offerings.   Regardless, any of them from Fred would be tack drivers.

Clear as mud?

HTH,

I know I dug this one out of the archives, but there is so little info out there on the 7mm Bullberry that I wanted to make sure it is accurate.

No, not quite -- and it must have rained the day that post was made as we NEVER see Ladobe slip up! (Had to pick on you, Ladobe, and did so out of respect as you truly are a walking cache of Contender knowledge and have freely shared it with those who share your passion for the single shots.)
 
 Anyway, the 7mm Bullberry is the 7mm Int'l Rimmed (30-30 necked down to 7mm) with the unnecessarily long neck cut back to give a case length of 1.760 (trim length 1.75"). I've been shooting one in a 20 1/8th inch Contender carbine  since the latter part of the 90s and love it.
 
It is superbly efficient, wonderfully accurate and generally comes within 50-75 fps of the Waters while burning a grain or two less powder to do so.
 
It is also mild enough in recoil that our twin boys, who are 8, used it this past season to take their first-ever bucks using the 120 grain Hornady SSP at around 2630 fps. They practiced much of the summer, studied whitetail anatomy till they knew every proper angle/presentation in their sleep and then made me quite happy as each executed perfect shot placement -- and from distances that most kids rarely shoot.(I am mobility-challenged and could not get them any closer, but we knew in advance approximately what the range would be and practiced during the long, hot summer months.)
 
That little barrel is responsible for dozens upon dozens of hogs, countless varmints and a few nice deer. To say it's a "keeper" would be quite the understatement.

SWH,
 
Since I usually rely on just memory, I certainly can make mistakes, more often maybe as I get closer to having one foot and 4 toes in the hole.      I also certainly don't mind, but rather appreciate it when somebody corrects any errors I've made.
 
I knew that Fred had just cut the long neck of the 7IR back for the 7BB.   They are otherwise identical.   That's why he lists both cartridges.   I chose the 7X30 Waters comparison simply because the OP didn't appear to know much about the 7mm's, and I assumed he'd make the connection easier with the Waters that is far better known to more folks than the 7IR is (yes I know the Water & Imp are longer than the 7BB).    One of those lets not make this one of my normal long winded replies to cover all the bases and possibilities I guess.   Probably wasn't raining, the pre 6 AM post suggests I had been up all night and maybe I was just tired.   I haven't been in bed since Tuesday morning, so don't count on this post being 100% either.
