Hopefully someone can help me with this one. I need a duplicate load for the Federal Premium 300Win Mag. with 200gr. Trophy Bonded bullets.

Also, because the price of Trophy Bonded bullets are really high, give me a pet load for any 200gr. bullet in this caliber. The rifle is a Browning A-Bolt II. Your help is much appreciated. Have a Merry Christmas.

200 gr Barnes Triple Shock 74 gr RL22 Fed 215M Norma brass @ 2950 fps

Works for most.

The Barnes TSX is one I considered for sure. I have been to two Bass Pro Shops and Carter's Country in Houston and they've all been out of Reloader 22. Seems to be some sort of shortage that preceeds each of my visits.

Thanks woods.

All the loads below should match the Fed Premium 300 WM ammo loaded with 200 gr. bullets.

Cartridge: .300 Win. Mag.(W)
Bullet: .308, 200, NOS AccuBond 54618
Cartridge O.A.L.: 3.340 inch or 84.84 mm
Barrel Length: 24.0 inch or 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.Matching Maximum Pressure: 65000 psi, or 448 MPa or a maximum loading ratio or filling of 120 %

These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.

Hodgdon Retumbo/81.3 g./3011 fps
Ramshot Magnum/81.4 g./3006 fps
VN560/75.9 g./3002 fps
Reloder-25/78.3 g./2997 fps
MAGPRO/79.1 g./2996 fps
IMR 7828/75.4 g./2992 fps

Start several grains below and work-up in 0.5 gr. increments, all while chronographing each shot (get a good chronograph). Don't exceed 3011 fps. I'd use Retumbo - I've tried it, and it is a very good powder!

Think the guy in the I-10 store did say it was the last bottle when I picked one up about a month ago, sorry. Don't give up on the RL22 though. I reload for six 300 win mags and RL22 works wonderfully in all of them. Also, for my 30-06 shooting a 200 gr Accubond. Have tried RL25, H4831, IMR4831, IMR7828, and IMR4350 and none of them works as well. The RL22 works best for my 30-06 shooting a 200 gr Accubond also.

Actually, the load I use for my 300 is 180 gr TSX with 76 gr RL22. 2 out of the 6 like the 180 gr and the other 4 it doesn't make a difference whether 200 or 180 gr.

How in the world do you get 81.3 gr powder in your 300??? I start crunching powder around 75 or 76 gr.

Your quickload info is always interesting. Does it say it is possible to get 3175 fps out of 180 gr TSX using RL22 or maybe RL25 (although I haven't been able to achieve the same accuracy as RL22). 24" barrel. If I can get there I am going to move my Burris Ballistic Mil Dot scope to that gun. I am getting 3116 out of 76 gr RL22 now with no signs of pressure, but it's getting pretty stout.

Thanks

woods, I have no trouble getting 89 grs. of Retumbo into Lapua or Norma 300 WM cases - although you might have to tap and compress with the bullet. My pet load is 83 grs. of Re25 with a 180 NBT - fits nicely in Win, Lapua, R-P, Fed, and Norma cases. Vel (26" barrel) is 3190 in a Norma case, ~3250 fps in a Win or Rem Case, ~3300 fps in a Fed or RWS case. The latter loosens primer pockets after 3 or 4 loadings, but cases are cheap. Never experienced a blown primer. I wouldn't recommend monolithic TSX-type bullets, when loading HOT - they are very touchy! 180 Nosler PTs or BTs are just a good and much easier to work with.

would you try running 79.5 gr H1000,
200g AB, GM215m primer, Fed or rem brass,

24" barrel

thanks

Woods, I called Carter Country today and they have the RL-22 in stock. I'll be there tomorrow so please leave me two pounds.

Skidly, I have decided to load this first batch with RL-22 200gr. Accubond and the 215 Primers. The brass is once fired Federal nickel.

Thanks for the help fellas.

ok, I was wanting AIU to run it in Quickload, I want to know what kinda pressure i might be getting. I used 72.5g R22 and got great groups at 70deg F, but at 20 deg F groups went bad!!

Skidly, QL predicts:

300 WM - 24" barrel
Win Brass
79.5 grs. H1000
2952 fps
63,278 PSI (safe)

300 WM - 24" barrel
Federal Brass
79.5 grs. H1000
2992 fps
67,209 PSI (marginal safe)

300 WM - 24" barrel
Rem Brass
79.5 grs. H1000
3088 fps
78,224 PSI (not safe)

Clearly, case volume is important!

Regards, AIU

thank you AIU, very helpful
