I don't have any firsthand experience, but I've read some posts from a couple very experienced SR-25 owners and reloaders who have had problems with the long throat in the SR-25 (compared to a custom bolt gun) and the TMKs not being very jump resistant. I'm told SMK projectiles are far more jump tolerant. But as shown above, for everyone who didn't have great results, there's always people who have fantastic results.
This doesn't really help you, but the real answer is "Try it out in your gun and let us know" because there's enough variance from sample to sample to completely change performance and behavior.
