Load Data for 208gr. A-MAX and .300WM and others.

[Tactical30]

Im getting some reloading components together so when I recieve my .300WM build back from Warner Tool I can get started on reloading.

The Barrel is a <span style="font-weight: bold">Bartlien 26" w/ 1-10 Twist</span>. For Target shooting mainly.

<span style="text-decoration: underline">Below is what I got together for load testing:</span>

I have got H-1000 and RL-22 for Powder

I have got Winchester Brass

I have got Federal 215M and 215 Primers

For bullets I have:
210gr. Berger VLDS
208gr. A-MAXs
190gr. SMK
200gr. SMK
210gr. SMK
220gr. SMK

I have looked on the Reloading page for data but I am trying to find some safe loads to start at and a rough max load end using:

1.) Winchester Brass/ Federal 215 Primer/ 210gr. Berger/ H-1000 or RL-22 Powder.

2.) Winchester Brass/ Federal 215 Primer/ 208gr. A-MAX/ H-1000 Powder.

I have seen "some" data but not alot using Winchester brass. I would like to know where you guys started (powder charge) when using these loads listed above.

Any data will help me out alot.
Thanks

RL22 is pretty good powder, but can be a little bit temp sensitive. The H1000 is pretty stable powder all in all. I think if you play with that combo you may well come up with a load that plays nicely in your setup. The H1000 I mean

200 gr bullets
H1000 starting 75.0 max 80.0
RL22 starting 69.0 max 73.0

220 gr bullets
H1000 starting 72.0 max 77.0
RL22 starting 67.0 max 71.0

Guestimate 210 bullets
H1000 starting 73.5 max 78.5
RL22 starting 68.0 max 72.0

I use H-1000 and the 208Amax @ 2955fps with a 24in barrel. Works great.

I shoot 210 Bergers or 208 Amax some POI w/ 76 gr H-1000, I think this chronos real close to 2900. I neck size with a Lee collet die and bump the shoulder back when I need to. I size my brass to fit fairly tight in the chamber. The bullets are into the lands. Both load combo's are in the .5's or .6's with an occaisional small group when the planets align and the gravitational pull of the moon is just right and there is no wind. The Berger's do better in the wind than the Amax or Accubond (200 gr), They also do a great job on wapiti.

Looks like the 210 Bergers and 208gr. A-MAXs and H-1000 is the way to go from all the info I have seen on here.

Any new info helps.

I've had extremely good success with Ramshot Magnum and the 208 AMAX.
It is very accurate over a large powder charge spread.

Very Helpful! Thanks!

Now if I could find one just like this for the 210gr. Berger!

Re: Load Data for 208gr. A-MAX and .300WM and others.

I do as Mitch does and use the average difference between the 200 and 220grn bullets for working up my 208 AMAX loads.

And yes H1000 is excellent in the 300WM with this bullet.

Re: Load Data for 208gr. A-MAX and .300WM and others.

208 AMAX
78.9gr H1000
Win brass
CCI large magnum rifle primers
bullet jammed .010" into the lands

2874 mean velocity, ES 19
3/4 MOA (5 shots 1.5" @ 205 yards)

Stock 700P 26" 1:10 barrel

I'm going to try backing the bullet off the lands .010-.020" on the next range trip

Out of the 200gr. SMK, 210 SMK, 220gr. SMK - which one is working best for you guys with the 1-10 Twist? 220gr.?

 

[Rob01]

Re: Load Data for 208gr. A-MAX and .300WM and others.

Depends on the rifle but a 10 twist will shoot all those well as far as twist is concerned.

Hey R0b01, do you have any .300WM load info you care to share?

Re: Load Data for 208gr. A-MAX and .300WM and others.

I got a barrel similar to yours. 1 in 10 Rock, 26".

My accuracy load for the 208 AMAX is 69.4gr of RE22. Didn't have much luck with Magnum on that bullet. But the 69.4gr shoots lights out. When shooting the dots, I pretty much get bored with that load cause its bull eye in the middle most of the time.

For 190SMK, accuracy load is 72.4gr of RE22.

For 220SMK, accuracy load is either 66.6gr of RE22 or 76.2gr of Magnum.
