I believe I read somewhere they are made by hornaday.(?)Be careful to compare price as there are alot more bullets out there that are cheaper than dogtown.(dogtown = good marketing skills)
example: 55 grn fb sp spitzer dogtown> $7.92/100
verses > 55 grn sp w/wo canlr,se> $7.45/100
for me these both group under a 1/2" and kill as effectly out of my rifle.
compared to nosler they do save you money,but is it comparing apples to oranges<
