New Berger 85.5gr. & T3 Varment
Posted by Tikkaba on November 8, 2019 at 6:02 pmHas anyone tried the new Berger 85.5 gr.
Will it stabilize in the T3 Varment 1:8 rifle?
If the answer is yes, can you share you load data?Dog Down replied 5 years, 3 months ago 3 Members · 4 Replies -

Most of us have only went as far as the 80.5 berger for testing but i would think the 8 twist will handle the 85gr given the design of the ogive.
Here is a link to the 80.5 testing…https://tikkashooters.com/public_html/general-discussion/berger-80-5gr-fullbore-testing/msg11634/#msg11634…I would think Varget would still be one of the best powders to test, buts thats just my preference.
If using Varget I'd start with the bullet .030 off the lands and start with a charge weight of 23grs and work up in .2grs increments…once you find node that groups well start playing with seating depth to dial it in.
If you don't have a micro adjustable die & bullet comparator to measure ogive i would strongly advise you get one…will save you money on components in the future and will help you produce the best handloads. -
Good advice Dogdown,
I have several hundred 80.5 Berger’s that I’ve never gotten around to testing, but you might want to use a powder other than Varget, although there is no inherent reason Varget won’t perform. I’m not at my computer but I recall a guy using a different powder to load for long range (might have been a different length barrel which would impact powder choice)I may have misread the post, I’m not familiar with Berger 85.5 bullets and assumed 80.5

I agree Eric there are other a few other powders that will do the trick. Varget will perform very well in the 80gr projectile weight range and its even listed for up to 90gr projectiles as a top powder performer…so if not Varget them something with similar burn rate I would still recommend.
I guess powder choice would greatly be influenced by availability…From what I've read approximate 24gr of Varget in a 24″ 8 twist barrel will get you somewhere in the 2700fps range in a 223…thats not screaming fast but if you have previously experimented with 80gr projectiles in a 223, you can fully understand and appreciate the 1000yrd capability of this load.
one word…FUCKING AWESOME!!!…sorry that 2 words lol…Bryan Litz (Berger) actually verified that an 8 twist will stabilize the projectile just fine with only a slight decrease in BC from the 7 twist that they based their BC numbers on…so I see no reason why it wont be super accurate out of a Tikka 8 twist. Might have to play with this new offering in 2020. Berger is really setting the bar high with all the new projectiles…exciting stuff for handloaders!
Hope the OP continues with this thread, very excited to see the results.
