there has been a lot of hype the last few years about using slugs for long range benchrest shooting. Has anyone tried slugs like the Nielsen 15.5 gr in .177 for field target? With a great BC is 0.62 and for example the popular JSB 8.44 has a BC of just 0.19 and the heavys I think we’re 0.23 that is an amazing difference. If I understand BC correctly it is hoe efficient a projectile is at holding its energy over distance While there is more to accurate shooting than just BC it surely is a major factor in accuracy especially down range
to stay under 20 FPE you could fire a 15.5 Nielsen at 760 FPS and be at 19.88 FPE or fire a JSB 10.34 at 930 FPS at 19.86 FPE which would have the flatter flight path? Would the slower slug have more speed at mid range (30) yds? Due to its far superior BC? And thus end up better at 55yds
FX is coming out with specially designed barrels for slugs which from my powder burner days probably means a faster twist rate I think they are going to offer it in 600mm length and 700 for the larger calibers which took many of the honors at the recent benchrest competitions
has anyone tried slugs in .177
I do think it would give me an excuse to buy a new FX with the slug barrel and a Labradar Doppler cronoghaph and see if the slug hype might have a place on the field target range

Hey Larry I saw your question while I was in Poland so couldn't answer. I have used them for FT, and the 15.5g worked very well in windy conditions. I had to hold two thirds less for wind than the 10.3 AA's I usually use. They also flew flatter longer do to the better BC. As for double chrony or labradar data I have none. Though I'm willing to test with someone who owns a labradar.
USARB has nothing that say's you can't use slugs, EBR doesn't allow it.
