Arron yeates Posted March 13, 2020 Author Report Share Posted March 13, 2020 Ps che chrony weight i input into the fx chrony was 9.5 grain as over 20 pellets on my scales were between 9.4 grain and 9.6 grains Quote Link to comment Share on other sites More sharing options...

Ultrastu Posted March 13, 2020 Report Share Posted March 13, 2020 If i was to put a good guess on the bc of the ft s .id put it at 0.022 . Might actually test them at the weekend and find out if im correct . Quote Link to comment Share on other sites More sharing options...

I need to stretch them out but not in this wind.. would be pointless lol as id be looking for better accuracy than the baracuda match 4.52mm 10.4 grains Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted March 13, 2020 Report Share Posted March 13, 2020 Ive found that they have pretty much the same trajectory as the 10.4 grns and the 9.4 grn hunter extreem .possibly a touch less drop but not a lot .An 8.44 grn jsb is much flatter Quote Link to comment Share on other sites More sharing options...

However if the FTs are traveling 30fps faster but lighterin weight. Is there any benerfit over the baracuda match that are slightly slower but heavier Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted March 15, 2020 Report Share Posted March 15, 2020 So having bc tested the ft and normal barracudas out my bsa pcp .the values are the same at 0.0235 . So the extra 30 fps will translate into a slightly flater trajectory and almost the same retained energy . 1 inch difference at 50 yds and 0.1 of a fpe . The lighter 9.5 grn should penetrate a bit less potentially giving a better kill on rabbits etc . If the accuracy is the same id swop to fts . In fact i have in one of my guns Quote Link to comment Share on other sites More sharing options...
Arron yeates Posted March 18, 2020 Author Report Share Posted March 18, 2020 (edited) The accuracy on the paper target for the ft's looks good but at only 20m when i removed the target showed totally different results. Below are the pics Edit....without my gloves on .... #mice lol Baracuda ft's at 20m. Baracuda match 4.52mm at 20m.

Not sure if its the head size or the weight it likes. I want to turn the power up a little to speed them up a little but dont want to void warranty Quote Link to comment Share on other sites More sharing options...
figgy Posted March 19, 2020 Report Share Posted March 19, 2020 (edited) Arron, go to the pirymid air site they have online calculators for all your needs. Link,. https://www.pyramydair.com/airgun-resources/widgets/convert.php?Units&u=14 My Daystate Huntsman runs in 10's can't fault its accuracy, I tried to up the power but lost all consistency. Spent hours getting it all dialled back in. Not much to be gained by half a foot pound down range. Edited March 19, 2020 by figgy Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted March 19, 2020 Report Share Posted March 19, 2020 So all this testing and mathematics, comparing various bc's and consistency and retained ft/lb, obviously taking into account the particularities of potential variations in barrel manufacturing tolerances, what have we learned? Well personally, adding up all the data and giving some considerable thought to the matter, the one conclusion that I ,with my limited intelligence, have deduced, is that, clearly, Arron is married or engaged.
