300 Win Mag loading

[Chucho23]

I’m looking for load info for a 180 grain 300 Win Mag out of a Tikka T3. I’m looking for bullet, powder type and quantity, length... let me know what information you have.

I do not have all of the specifics handy, but my T3X in 300 Win Mag loves the 190 grain Bergers. Velocity is 2900 fps.

At 100 yards, using a bipod with rear rest (sand bags usually), and my quality of shooting for that specific shooting session:
On an "average" shooting day, a 3-shot group is 0.74" outside to outside.
On an "good" shooting day, a 3-shot group is 0.63" outside to outside.
On a "great" shooting day, a 3-shot group is 0.39" outside to outside.

I think a tikka in 300 win mag would be well suited for the 185 classic hunters from Berger. They are designed for the smaller mag boxes.

My Tikka likes 180gr Nosler Accubonds with H1000 and 180gr Nosler Partitions with RL22 using load data off Nosler’s website. The AccuBonds shoot < 0.5 MOA and the Partitions shoot 0.6MOA. I use the AccuBond load because of the temp stability of H1000.

I realize this is the reloading forum however looking for input on a good bullet for a remington 700 .300 win mag; for whitetails i would think the 180 grain Nosler Accubonds should be good; right? Thanks,

I’m shooting 181 hammer hunters over 75.5 grains of 7828ssc. Settled right at 3100 FPS with good accuracy. I’m shooting a cooper and have a little longer mag than the tikka so I can seat further out and get maybe a few more FPS out of it. Gonna switch to rl23 though and see if I can keep the velocity and accuracy while gaining more temp stability.

I don't have a lot to add since I only shoot coppers out of my 300 WM, but if you want to shoot copper you will need to limit weight to 175 gr class or less because of the 1-11" twist rate on tikka's.

However, I bet that 175 LRX with 79 to 81 grs of H1000 would be a fantastic round. I shoot the 190's out of mine with H1000 but plan on moving over to the 181 gr hammers with RL23 for my fall elk hunt.

I recommend grabbing ADG brass if you can find it.

I’d feel comfortable hunting anything in North America and most of Africa with that load. Knock em dead.

I've had great success with 185gr Berger VLD hunters. If I do my job, it will shoot .75 groups all day with the factory barrel. I'm starting to play around with the Accubond LR in 190gr with some success.

H4350 and IMR4350 have been my powders of choice

You don't need an accubond for Whitetail. Any bonded bullet is great, and at 180gr most non bonded bullets are fine. Look at the hornady interbond/interlock, eldx for cheaper bullets

My tikka barrel loved 168gr Berger's and imr4350 shot 180s accubonds well too, didn't care for 200gr eld-x's

26" barrell
180 AB
H4350, 71 grains
Winchester brass
Fed mag primers
Loaded to fit in the mag.

1/2 MOA +
3200 FPS.

I'm not sure what the max load is with the H4350, but I'm either right at or slightly above. Been shooting this load since 2010 or 2011. It's devastating on Elk and Deer into the mid 600s. It shoots very flat and the bullet stays together.

My tikka 300 win mag liked 180 accubonds. Sub 1/2 moa with 75 grains imr7828ssc 2940fps. Shot great but recoil was pretty stout.

 

[DB Cooper]

180g AB
IMR 4350, 68.5g
Horn. Brass
215M primers

Yep that's the exact load my tikka barrel liked with accubonds

 

[excaliber]

Many a 300WM has liked 75g RL22 and 180g Nosler Accubonds. Mine too.

 

[PRC_GUY]

What powder, bullet,brass you have, without any of those three, we have no idea what to recommend!

 

[wind gypsy]

I’d look at 4831ish burn rate powders.

I was started load work up for my tikka 300win the other day and had some strange results with reloader 26 every group was all over the place zero consistency I thought the bullets may have been unstable but switched to h1000 and couldn’t shoot a group over 1” it was pretty amazing the difference in two powders with basically the same burn rate

2 of my 300s liked 70g of h4350 in Norma brass using a 180 accubond. This is a max load according to nosler but in my 2 rifles I had no pressure signs. I tried h4831 but it wasn’t as accurate for me with the 180s. I had success with h1000 once I went to 210 Bergers. 75g was my load for those.
