Straight 284 with H4350 charge weight?

[KWeigel]

Going to start working on my 284 that I have had ready for three months and still haven't shot. Going to be using H4350 with 180 jlk bullets with a target velocity of 2800 to 2850. Accuracy trumps all. Can you please ball park charge weight. 32" muller modified with 250fb.

50 to 52 grains. My sweet spot is 50.9 to 51.5. 2850 fps.

I am at 51.4g with 180g Hybrids. 31.5" Brux.

Whet velocity is that running?

2820-2830 fps.

51.5 of H4350 and a 180 Hybrid is my go to load. I get 2810 to 2840 velocity (depending on which barrel if use) and it shoots lights out. My current 30" Bartlein shoots 2830. My last one went a little faster at 2840. I had a 31" Brux that would only make 2810. All with the same reamer so barrels do have a mind of their own - but every one shot the same load extremely well.

Gonzo what primer has worked best in your application considering all other data given? Do you also know what throat or free bore you have? Thanks

 

[gilmillan1]

Fed 210s.

 

[coford]

I use CCI BR2 primers and my freebore is .220.

See above for charge weight - Wolf/Tula primers for me.

What is your relationship to the lands with the 180 hybrids? Thanks, Matt

I'm running .012" jump on the 180 hybrid

I am using 51.6 grains of H4350, F210M primers and 180 hybrids. They are running 2830 out of my 28-inch barrel with single digit ES. I have a couple of five shot groups under 0.2 MOA with this load and new barrel. My freebore is 235" and I am jumping 32 thousandths.

I'm using 180 vld over 54.0 gr of H4350 super accurate. I would start around 50.0 and work my way up to 54.0 . You can push them little harder but not much on a straight 284

 

[dragman]

I used,
CCI 250s
53.5 grains coated bullets

What length barrels and coal ?

 

[284winner]

Anyone out there shooting 3.000 or under coal ? Wondering what velocities with 24" bbl? 162/168 gr bullets.

Any idea why at 50.5 I'm at 2868 fps?? H4350 and 180 hybrids

54gr in a straight 284? That would make short work of my brass.

I shoot 51.5 H4350 CCIBR2 230fb jumping .013.

Not sure whar barrel length you have but that could be part of it. Could be a HOT lot of H4350. A few buddies got some hot stuff last year.
