Default 140 gr Federal Trophy Bonded Tip reload data.

Is anyone loading Federal Trophy Bonded Tip bullets for 7mm-08 ? Can't find load data for 140 gr bullets... Loading looks similar to what I've been using for 140 gr. Accubonds, but I'd like to hear from some members as I'm quite new to reloading... Presently, I have Varget, H4350 and RL19 on hand.... As always, I would start my prepared loads low and work up, checking signs of higher pressures along the way... Thanks in advance..

140gr is a 140gr, you don't need specific data for TBB bullets

True! Pull up the Hodgdon reloading data and just use 139 or 140 grain data, Start half way between min and max and work up .3 at a time. LOA will likely have more effect on your groups than the specific powder or charge weight. It is how I loaded for my 7-08. Horn 139 SPBT in Lapua brass, I started with H4350 and found a good accurate load at 2920 fps with that powder so never looked any further. Best of luck.

Not exactly true. Monometal bullets (Barnes x bullet, etc) have a much longer contact surface than a cup and core bullet of the same weight and don't operate at the same pressures for a given powder type and weight.

They need to be treated differently

Actually you are repeating an often made comment that is no longer true. It originated with the original Barnes Monometals that aren't made any more. Their new, last 25 years at least, Mono bullets have large rings on the bullet that actually reduce the contact area to be the same or in some cases less than same weight Cup and Core bullet.

If you check Barnes load Data for their 140 grain TSX and TTSX you will find their max published load for CFE223 is 1.1 grains higher than Hodgdon's load for the 140 SFT SP. The same is true for 4064 41.4 Barnes vs 40.5 Hog, The only one they list as lower is Varget 41.2 Barnes, 42.2 Hog
