If you do't want to re-tune, you can use the 25gr boosters from Aftershock. These should give you the same performance as your 125 gr. field tips. I use them with the Grim Reapers to get to 125 grains. You will maintain your FOC this way too.
I am not familiar with this product, but I am going to look into it and experiment with it after elk season as I do like the feel of a 125gr. Thanks for the suggestion.
It sounds like you know how to tune well enough that there shouldn't be much use for using a mechanical head unless you are looking to introduce some problems into the equation.
I guess it is human nature (at least mine) to want our cake and eat it too. I have been quite satisfied with Muzzy 3 blade 125 for many years.
However, if I can achieve the same in the way of penetration (for me that would mean a complete pass through) but also have a bigger blood channel such as one can expect with the rage, then to me it would be the best of both worlds.
As I mentioned, I was not impressed with my initial use of them last year to be competely sold, but at the same time I have heard enough good things about them that I believe they work very well, for at least certain set ups and for whitetailed deer.
I would never even consider using on elk although I guess there are some people doing so.
I am now trying to find if I can make my set up "applicable". Increasing KE, while it may or may not be a problem, is not an option for me unless I upgrade to a faster bow,which I don't intend to do, at least not in the near future.
Thanks for the input.
