All,
When responding to another BT-99 post .. it got me to thinking. What re-load have people found to work best in their fixed choke BT-99 ?? I have only had one outing with my 1979 34" fixed full choke .... and with the limited sampling I did ... found the STS reload to work best (not a big difference mind you ... but just seemed to hit the bird better). I plan on doing more, better testing this spring. Also, the fixed full choke seems to be more than needed at 16 yds. Does anyone have any re-load tricks to try and "open" the pattern some ?
Thanks, Brian

1) STS 1-1/8, 7.5, fig 8, green dot, ~1200

2) AA 1-1/8, 7.5, DRA-12, claydot, ~ 1145

3) F-top gun 1-1/8, 7.5, DRF3, green dot, ~1200

I agree the full choke is "more than needed" at 16 yds. But I don't think reloading to open the pattern is worthwhile. Makes much more sense to me to load 1 ounce of #7.5, anywhere from 1150-1200 fps. You'll have reduced recoil and reduced cost with no reduction in performance....1 ounce #7.5 through a full choke is still more than needed from 16 yds. And you might even consider 7/8 ounce of #8 for casual practice. Same pellet count as 1 oz of #7.5 and cheaper still. Unless you're chasing an ATA average, all those things can be more important than the 1 extra target from a stray pellet in that extra 1/8 ounce.

Likewise, 1 ounce of #8 will be the same pellet count as 1 & 1/8 ounce of #7.5. So, the only difference is the individual pellet energy and I think #8 is plenty adequate from the 16.

FWIW, my standard load for all clay games for the last 10 years has been your #1 with 1 ounce of #7.5 and 19 grains of Green Dot...1200-1225 fps. All I vary is the choke...IC for skeet, Mod for SC, IM for FITASC and Full in my 1970 BT99.

At one time I had 2 BT-99s one with IM and one with Full. I shot my best Singles average with the Full choke gun. In truth a more open choke gun does not have a wider pattern it only has a weaker core in the same width pattern.

I used to shoot 7/8 ounce of 8 1/2's in mine for a while and it worked well 96% of the time a couple of shoots. Smokes them too!
