Looking at adding some APA Little Bastards III's to a few barrels I have. Wondering if I should just get the 30 and use it on the 6 and 6.5 mm's. Any loss of performance? It would be nice to just get the 30's and use them on that and anything smaller. Are you better off getting the 6.5 for 6.5 etc?

Thanks

I had a Griffin Armament minimalist taper mount .30 cal brake on my 6.5 creedmoor for a couple years. I got a good deal on the same model 6.5mm brake, so I swapped it out.

No noticeable difference whatsoever.
