I’m starting to work up a deer hunting load for my Bergara 6.5CM. Picked up some TTSX 120 grain projectiles.
I’ve always used H4350 in this rifle with good results. Anyone have a good load for this combination? Are they seating depth sensitive? (The throat on this Bergara seems pretty long.). My initial testing has been mediocre…
 
I run them in a 260 rem, close but not exactly the same as the 6.5 CM (a little more case capacity). I run them at 42.7gn of 4350, but the load for a 6.5 CM would likely be a little less because of the different case capacity. I have always had best results with the Barnes bullets around .050 jump, plus or minus. I actually like the 123 LRX a bit better than the 120 TTSX, but they are very close for load purposes.
 
Not ttsx and with 123 Scenars in a short 6.5 barrel, I just ran some tests with h4350 based off suggestions from the Hodgdon webpage and got great speed and accuracy a ways below their listed max.

Cant remember exact charge.
