TC Contender and +P loads

[35remington]

It is not terribly hard to run the 7-30 Waters or 35 Remington to levels that give notice the original Contender frame is being abused. If you pay attention to what the gun is telling you and back off the original frame can do decently well. Ignore it, or not recognize it when you see it, and problems will make themselves evident.

Well after having shot tens of thousands of rounds through my half dozen frames with loads most would question today, with only replacing springs, I must have been shooting fairly soft loads.
The IHMSA circles I was in, I never once recall anyone having a frame issue. Maybe I just didn't hear about it when it did happen.
Carry on gentlemen and be safe.

I have some JD barrels.
If you use HIS loading data, all is well.
Some thought you could get a "little"more but JD already did that!!!
All mine [309jdj,411jdj, and 45-70 will do just what JD said and in most cases that was more than enough!!!!!!!!!!!!!!!!!!
The big problem is the standing breach on the frame , it can take only so much "push" based on the psi in the case head.
The bigger the case head the more the square inch [the si in psi] and the more the "push" [ the pressure in psi ]
