100 GR. SPR BTSP | Hodgdon | Varget | .243" | 2.650" | 31.0 | 2674 | 42,700 CUP | 33.7 | 2838 | 50,400 CUP |
33.7gns varget gives me a 3/4" group at 100yds in my 20" barreled tikka m595
I would have been chuffed if 33.5gr or 33.7gr of Varget had achieved the suggested 2838fps with the Sierra 100gr BTSP....Even 34.5gr didn't achieve a legal velocity !!!
Only wanted 2810 !!
Would have settled for 2775 !!
Shame because it was beautifully accurate with 33.5gr.
Good luck.
Philip
Are you saying it didn't even reach 2450 fps muzzle velocity?
What does 2450fps refer too ???
I got
33.5gr 2550
34.0gr 2675
34.5gr 2720 (1643ftlb)
I need t try a slower burning powder (rifle .243 Sako A2 with 22" Border Archer barrel)

Minimum 100gr
AND
Minimum velocity 2450
AND
Minimum Ftlb 1 750
All three must be achieved to be legal in Scotland (apart from Roe 50gr 2,450fps and 1000ftlb)
(England min cal .240 and Ftlb 1 700)

forgot about the min 1750 ft/lb requirement - what a pain...that means I need to buy new powder too...
I havent im afraid but Hodgdons site gives 2838fps,cool - you wouldn't happen to have chrono'd that?
