Does anyone have experience with hybrid V-100 and Hornady 178 bthp or 208 Amax? Lack of powder has forced a change.Any info would be appreciated! Thanks
thank you, I will keep that in mind when I buy powder again.I also have some Superformance that I am going to try.
How did the Charger test go? What twist is your barrel? 10 or 12. I have a fn pbr, I'm wanting to run 155 to 3200 for competition speed. Have you considered h1000?

Found another good load. 78.0 grains h1000. Fire formed nosler. 200 Berger hybrid. 2.943 to ogive. 10/1000's off lands. About 2935 fps
Finally found a load for 210 smk's.

77.4 gr Retumbo

jumped 0.0010 / 2.865 ogive

During load development I shot a ladder at 600 yards to determine my powder charge, then I loaded rounds to find the right seating depth. I loaded 3, 5 shot groups. The first group was jammed .0010, it shot about 2 inches. The second group was just touching, it shot about 1 inch. The third group was jumped .0010, it shot about .5 inch. Have you guys seen that big of a difference just with seating depth?

I have tinkered with them and found its basically a 210 Berger vld's twin brother. They shot the best at or near the lands with me running h1000. The bearing surface is pretty far back on those bullets
something else I found with smk's. If I set my seating depth from the ogive, the oal with be within a thousandth almost always. The bullets seem to be very consistent.
My .300 WM load:
Hornady 208 A-max
Win Brass
CCI Mag primer
76.8gr H1000
3.648 COAL
Pulled the 5th shot a little unfortunately, but this was my first 5 shot group with this charge. Still very pleased with it.

See post 363. I use 77.4 grs of Retumbo. Work up to this as your chamber may be different.
Thanks I must of missed that one.

I am loading 208 amax over RL-22 into FC brass. I have noticed that federal brass is heavier than others and I am assuming this means less volume inside. With a recent test I was loading per Hornadys data and getting velocities above what the book indicates. Worked up to the max load with this result.
72.4gr RL-22
215M
FC 07 Brass
208gr AMax
COL 3.43"
5 shot group with an avg velocity of 3059fps

Ref the post above: trying to slow these down a bit and it's not working out. Worked my way down to 71.5gr RL22 and we are still above 3000fps. Causing heavy bolt lift and a few fail to extract. Reading my books it says lower end charges can lead to over pressure. Not sure I understand that but also not sure what to try next.

I'm just starting to work up a load with Black Hills Brass (Win), H4831, and the 178 Amax. Care to share your findings? Of course I will work up slowly, but it's good to have a reference point.
Or does anyone else have a decent load for this combo.

One more month and I should have all my Federal brass here. Looking to build 208 AMAX & 190 SMK loads with IMR 7828SSC. With the "un" availability of H1000 I'm leaning towards this to be "the" powder for me. Savage 24inch HS-Precision platform.

Been having really good luck with Retumbo and the 230 bergers as well as the 215's. I've got a 30" Broughton 5c and it gives me about 70 to 100 fps more than h1000. Very good powder for the HEAVIES.
whats every one's primer of choice? i have a long range shooting school coming up in a september that i need 500 rounds of mach grade. i will be loading hornaday brass with retumbo and 208gr A-Max's just haven't found much on what to light it with. i haven't loaded for precession long range just gas guns to this point. not looking to get it dialed in 100% as I'm no where that good. just going to make an attempt at a ladder test then plan to load the needed 500rds as close to exact shell to shell as i can.
I did an unscientific test of CCI 250, WLRM, and rem 9 1/2. I loaded 3 rounds with each primer and shot groups at 100 yards. The CCI's grouped the best, so that's what I use.

Some powders are just that way. H110 and Win296 (magnum pistol powders) are almost always compressed loads. Anything less than 95% case fill can be dangerous with some powders. On the H110 and Win296 there is no "starting load" there is just "the load" backing these powders down more than 2% is not advised.
This was shot out of a VERY long throated Win Mag.
Is .195 moa and 3090 to 3110 fps.

Just a quick THANKS for all the posts on 300 wm.
I went with this as starting point from reading posts. then up and down with powder. 76.8 perfect!
76.8 h1000
208 amax
new federal brass and primer
savage law enforcement / ps stock / 1-10 twist
3.6 oal
.40 moa (would have been better but my skills are very rusty)

How far off the lands are you seating the 208 HPBT? I think I have the load at 20 off the lands, 208 HPBT being pushed by 77 H1000. Its under 3/4 inch but I need to egt it down to half moa or better for 1k shooting.
I am tagging this for references
I'm assuming this is the FCP-HS Precision platform with the 24" barrel. I had some initial "good" results with IMR 7828SSC but they were not
consistent with outings. And now I can see H1000 coming back in stock, at least 1lb'ers that is. I went out once with 70 some rounds and the groups
tightened up considerably, even with a warm barrel. I got best from 75 and 76, and for some reason they opened up at 75.5. So I now have 40 ladder loads ready 74.8, 75,75.2, 75.5, 75.8, 76, 76.2, 76.5. I should make some for 76.8 but the original 77 opened up a bit. My AOL is 3.468 and am still having issues where the AMAX tip is getting nicked in the mag. Have you seen this or have you just been doing single loads and no mag? I'm also using once fired Federal brass with Federal Magnum primers.

Anyone playing with the Nosler 220 Custom Comps? I cannot find info on a starting load.
Thanks!
Thanks!
here ya go, i had luck copying the smk suggestions for the cc's, just start low and work up
300 Winchester Magnum ? Nosler

am i reading that velocity correct, wow! would like to know what brass and elevation this was done at, it has peaked my interest
also what was your start load?

The cases are once fired Mil Spec Federals and they are loaded to 3.6" (.010" off the lands), Right now I'm working on magazine length loads at 3.90"
Starting loads were 78gr's and I went up to 82gr's. Elevation for load development was at 200' The group quoted was shot at 4300' with a DA of 6500'
(I live at the foot hills of the cascades so elevation changes are always monitored with a Kestrel )
This is the load data sent to me from Berger:

230 Berger OTM , virgin Winchester brass, 76.3 Retumbo , fgm215 , 2895 fps. .1 moa or a tad less. Shot from a 30" Broughton 5c 1:10. Shoots very well out to 1100. Haven't stretched this load farther yet but I did shoot some 215's out to 1330 yards and only needed 10.2 mils to hit. It's a screamer...
I'm thinking of 75.3-76.8, in .3 increments. I wanna shoot 3each , which is 6 loads for 18 shots. I feel like I may miss a node low or high. Should I just shoot a ladder test at say 200 yds, from 74-77, in .3 increments? Seems like a wide range.
more info on what your loading.
Sorry. 73.5-76.8. H1000 and 208 Amax in my 110BA.
start at 74.5 and go in .3 increments, at 75.8-76.3 should be a sweet spot, but i would go to 77.2 to be sure your not leaving nothing
on the table, you may see a node aprox-every 1.2-.4 grains.
after you find your powder node work your seating depth.be safe and keep a close eye on psi.
a 200 yard ladder test will show you that you wasted your time at 200, a ladder test under 500 yds with a 300wm is a waste of components and time.
So are you talking about an OCW test? This is my 110BA 300WM.
