Finally got my Nitro's in and patterned them yesterday afternoon with the Pure Gold chokes. My SP-10 with the PG .690 put 356 Nitro #H210 #7 pellets in a 10" circle @ 40 yards and put 250 Nitro #H210 4X5X7 pellets in a 10" circle @ 40yards. The PG .710 put 324 pellets of both the #H210 #7's & the #H210 4X5X7 in a 10" circle @ 40yards. I was expecting 400+ from the PG .690/Straight 7 loads and was surprised at the PG .710 shooting the same patterns with both loads. This is my first year of really tinkering with the SP-10 and Nitro loads. I would welcome any comments.
Post up some pic's of your patterns and the wad that was in the shells. :icon_thumright:
I don't have access to a digital camera.
SK you have two good chokes for either load...depending on overall pattern the .690 for the 7's
and the .710 for the triplex may be best? :icon_thumright:
What do you think about those slow shootin 5$ WIN. SUP. PB 6's? ;D
They don't hold a candle to these Nitros!! :z-guntootsmiley:
You didn't mention the temperature when you patterned.
Something's i have learned from this site and applied have proven as effective
as claimed. Deep cleaning a bore and choke, temperature effect on patterns,
choke dimensions to bore diameter.
One thing that seems overlooked and pointed out
by our more knowledgeable contributor's is allowing a choke to break in ! I see chokes for sale
in the classified's that are only fired three times or less.
I observed a pg 690 improve gradually over
thirty rounds fired. Also saw a dramatic improvement with a lightly polished 720 choke that performed
so poorly when new i considered it a lost cause. Also noted early on that mass produced ammo was
inconsistent enough to convince me to handload all my ammo.
