RE: Excal arrows?
I may be wrong, but I don't think danny Miller even stocks the standard Excal carbons [357 gr] Once I tried his 431's I converted all my stock 357's to brass inserts. The 10 pt arrows are almost identical to Millers, except for the plastic nocks and a weight of about 420 gr.
I've done some experimenting w/ blazer vanes, need to do some more, but seem to recall they grouped well w/ b-heads but not the same as field points.
All Excals have manual safeties
Out of thousands and thousands of shots w/ about3 dozen carbons I've had two break, one stuck in foam 3-D and one hit a tree.
