Im getting ready to order powder again and have never tried Swiss. I shoot all .54 or 58 calibers. Ive usually used Goex FFG or KIK FFG. Is Swiss FFG appropiate? Or should i mix the order with some FFFG and 1.5?
A friend has had good luck with Swiss 1.5f in RB guns as accuracy loads. I use FF and FFF. 1.5f at 110 grains puts my 54 about 10" low at 100 compared to fff.
I would point out that in 58s you may find you will be limited to about 100 grains of powder.
Limited testing has shown that 110 causes an unexpected increase in fouling. Mad Monk says this is due to the combustion temp of the Swiss. Apparently the 58 is a bore size that causes problems with this
?
I can shoot my 16 bore rifle (67 cal) virtually all day with 140 gr of FF.
I have not had any problems with 50 and 54 calibers but use 90 gr FFF in the 54 (vs 100 goex) and 75 in the 50.
Both produce far less fouling than Goex and velocity is as good of superior to FFF goex.
I can sh0ot 20-30 shots from the 50 with no wiping using beef tallow for patch lube and blowing in the bore between shots. Accuracy is pretty good too and it seems to shoot better unwiped than wiped with tallow.
I really like swiss and don't buy anything else. I use "Null B" for prime.
