35 Whelen Max Effective Range

[35WhelenAI]

200 TTSX is carrying over 2150 FPS at 350 yds when started at 3000 FPS which is safe with modern powders based on using Sierra and Speer data extrapolated and worked up safely using case head expansion. The Sierra 225 gr boattail can be pushed 2,900 FPS with modern powders using published data from Sierra. How much further reach is needed when talking 350 to 400 yards with this cartridge?

Email Barnes. I’m pretty sure the 225 tsx was 1600 and the 200 was 1800 when I emailed them but can’t find it now. But that doesn’t mean it is actually good expansion. For the whelen I think that the partition is the best bet for down range expansion. Accuracy wise my jes rebore really liked 225 sierra gmk. Bad bc though and was at 1800 fps (stated minimum from sierra) around 400 yards.
Need a .35 cal eldm or tmk

You don't build a .35 Whelen if you're worried about bad BC. Pretty much all .358cal bullets have bad BC.

You build one to knock the hell outta stuff under 300 yards. It does that quite well!

I'll second that. Out to 350 yards with any Barnes first Gen 200, 225 or 250 X (elk and deer with each) along with the 200 TTSX (more elk and deer) expansion from experience is not an issue.

However even though I haven't used a 225 gr Partition in the field, I can't think of a better mix of expansion and penetration based on field performance I have seen from other hunters in camp over almost 30 seasons. I just don't care for the rapid initial expansion and damage if it hits anything hard, otherwise fine choice. That's why I've stayed with the Barnes since I started loading in the mid 90's.
