Using the 105 grain BTHP?

Anyone tried the Nosler 115 RDF? This is in a bolt gun.
Thanks

Looking to load up something to start.  I have some 6mm stuff from prior 243 project.  

87 Vmax
65 Vmax

70 Nosler ballistic tip

50 SBK
70 SBK
80 SBT


I have quite a few powders, but not the two "hot ticket" ones (LVR and 223)  

Varget
BLC-2
H322
H414
H4895
Benchmark

RL 10x, 15, 19

VIHT 133, 135, 140

Finally finished my 6mm Arc build……and yes I’m new here so I figured I’d join up if I’m becoming part of the 6mm Arc family

Looking at reloading data and can only find Hornady published loads.

I’ve never handloaded for a gas gun

But I have 3 decades of handloading experience in bolt action rifles 

Question:  has anyone tried Reloader 15.5 powder.  I’m hearing it’s very temp intensive and it falls in between:

CFE 223 and Leverevolution

I’m looking to develop a deer hunting load and target load 
Both these powders give the best velocities. But are not known for temperature stability. It seems Reloader 15.5 might be ideal for speed and temp stability. 

Leaning towards 3 billets for hunting:

90 grain Nosler accubond
95 grain Nosler BT
103 grain Hornady ELDX

For target I haven’t decided but something from Berger or Sierra with high BC

As I type this message, Brownells has Hornady 6mm ARC brass in stock (50/box). No telling how long it'll be that way. I got two boxes for myself.

MidwayUSA has 25% off Barnes 112 Match Burners.  Just got a couple hundred to try out.  Man, those bullets are long.

I just built an ARC using an Aero upper, Tactical Kinetics 20" barrel, Odin AGB, Faxon bolt, cheap 17" handguard, mounted on a Joe Bob's lower with a 3.5# single stage trigger, topped with an Arken EP5 MRAD scope and 20 MOA mount. Went to the ranch yesterday with my boys and nephew to try our luck shooting out to 1k yards. Once dialed in at 200, we hit plates at 450yds, 650yds and then 1000yds. So much fun and 1000yds is a long ways, especially when you've never shot past 500. Lol. The ARC did well and started shooting great after 40 rounds, however, it doesn't like the Hornady Black ammo much. My thrown together 108gr ELD-M reloads shot great and were used for the 1000yd plate. Now to work on precise load development and shoot more.

I bought a Howa Mini barreled action with the 20" barrel from Brownell's.  Also bought a Stocky's VGM for it, along with the Jefferson Outdoors blind mag bottom metal.  Everything arrived a couple weeks ago and it's all assembled.  I ordered the Talley extended rings for it and have a 3-9 Nikon on it right now.  Too late for Deer season for me, but I'm ready to load some ammo and see what it can do.  

Has anyone got a sense for whether the Howa 20" barrel responds well to a barrel break-in process?  I'm going to do a shoot-clean cycle for the first 10 shots while I get the scope more or less sighted, then maybe a couple 5 shot groups and clean before I do any serious load development.  

The consensus I got from speaking with a few smiths was that custom barrels benefit less from this than factory barrels, and ideally, I'm not looking to go through dozens and dozens or rounds, and prolonged cleanings for what will be a hunting rifle for me.  

That said, like the old saying goes, "Only accurate rifles are interesting".

Looking for thoughts On Bear  Creek Arsenal offerings. I keep kicking around a 6mm ARC upper & BCA  recently caught my attention.

Lets here the good the bad & the ugly if that applies. 24" barrel interest me or at least 22".

Anyone here have a Garmin chronograph? Is it any good?
