Doubled 150
Welcome to ML hunting - i think you will find it gripping...
I can not think of a good reason to shoot 150 grains of anything, especially from a Wolf (as I think the Wolf is a shorter barreled ML).
I am certainly not an expert on the use of PB's but from your Wolf 100 grains will work just fine with most any bullet you choose to shoot + it will be or should be very accurate. You as a bowhunter know the value of accuracy.
This is just me so do not take it to heart, but there are better choices of projectiles out there than the PB (sorta like your personal choice of a broadhead)and I am thinking FG would recommend a further reduced charge than 100 grains. But with the Platinums maybe not.
A 180 yard shot is do'able but there will varibles as there are in Archery...
Good luck - shooting a ML and hunting with a ML is pure fun...
