sorry to say,I have 2 setups 1)DB .10 with full length sleeves 2) SP-10 with primos jelly head
both of these shoot in the hi 200's @40 yards 10" with Nitro H210s
shot them today with the new hevi-blends and got no more hits than my federals,winchesters and other
older lead shells.<100 hits.
shot 8 shells out of the 15 I ordered (spent about $8.25 each with shipping)
NOT for me but your results may vary I will be sticking with my Nitros.
