Finally got the bucket list gun of the Browning Safari Grade .300 H&H Magnum. It is kinda large for our puny Florida deer but that and pigs will be the main quarry for a while. Any suggestions on loads for deer? If there is a universal load suitable for deer to moose I am not apposed to simplifying things for future hunts. I have some 180 gr Hornady 180 gr Interbond factory ammo coming in the mean time.

SOrt of in a similiar situation with a 300 weatherby. I am looking at 165-168 grain bullets at a slightly reduced speed. If I were looking at bigger game then deer , i jack up the velocity and use a 180 grain TSX or Partition .

165 grain Nosler BT with enough H or IMR 4350 to drive it to around 3000fps. Super accurate and Martian Death Ray lethal on deer.

Not an H&H but a .300 magnum. I use 180gr Core-Lokts and Interlocks at 2835fps using IMR4350.

If it were me I'd pick up some 130 TTSX's, run them at the speed of heat then go shoot any deer or pig in the state.

If and when I decided to go shoot moose I'd worry about working up a new load then.

I agree with trying out some 4350 and a decent 165-180. Chances are it'll be accurate and be an awesome deer and hog killer.

180 gr Nosler Partition.

70 grains H4831 and the 180-grainer of choice.

I load 150 Ballistic tips and IMR 4350.

I always load for elk with my 300H&H but I have used it on deer and antelope too when I got the chance. I use 200 Gr Nosler Partitions and a load of H4831. The partitions expand of the chest of an antelope, but don't blow up on the shoulder of a bull elk.

My rifle shoots 69.3 Gr with a Fed 215 primer into 3/4" to 7/8" at 100. It does all I could ask of it. My friend Don has an old Remington 721 in the 300H&H and his gun shoots well too, but used a bit more powder. I think he said it was about 71, but i am not sure.

Never load to what someone tells you for powder weight. Always work it up yourself in your own rifle.

This is the right answer. No need to look further.

I have a 165gr GMX load that shoots great. That is probably what I would use, since it is done.

Starting from scratch, strictly for deer/antelope. A nice moderate load with a 165gr Hornady IL/IB, or Nosler BT/AB would be my pick.

my load is 71g of RL22 and 180 TTSX's. It has worked great on elk, so I suspect it would kill a deer too..

pacecars, I am trying to keep it simple with a Win Mag, so my rifle only sees 180 gr Partition. They are consistently accurate out of this rifle, and I cannot imagine anything I could not pursue with this package.
That said, were I starting over, I would also trial the 200 gr Partition and the 165 gr ETip or TTSX. The most accurate would get the job.

I say simplify, I shoot 200 and 220 gr Partitions for all game in my M-70 300 H&H's, enough H-4831 to run the 200's to near 2900 fps and the 220's at an easy 2750 in the M-70's 26" barrels.

Hunting with the 220 NPT's through a Lyman receiver peep is perfect for all CONUS game and a whole hell of a lot of fun.

I use W-W brass and Fed-215 primers.

Pushing light for caliber bullets at high speeds for deer seems like a recipe for bullet blow ups and lots of blood shot meat.
I've seen it with 7 Mags, 300 WM, etc... and it isn't pretty. Shooting a 300 Mag of any flavor, I would slow it down a bit and use a bullet that won't over expand at those speeds. In my experience, this starts at the 180 grain bullets with some type of controlled expansion. This would not include Ballistic tips and would be iffy on Partitions. If price wasn't a concern, I would go with Swift Aframes- most predictable expansion I've ever seen with any bullet I've ever used.
Heaven knows you will still have more than enough power to kill any deer on earth and elk, bear, moose, or rockchuck ever born.....

That is the bullet I used in Africa with much success. On top of 64.5gr Hunter. Average is 2906. I had pushed it up to 3000 with nice groups but backed off. Do not need to Hot rod an H&H.

I am w/ hanco😀

180gr GameKings and enouth IMR4350 to push them to 2900ish.

Taking in easy on the old girl (and me :))

For deer and hogs I would load lighter bullets. Means flatter shooting and less recoil. 130 to 150 TSX would be lethal for almost anything you will ever face.

I used the 200 gr. Speer pushed to 2850 with IMR 4831. I have a sample of one, a little 6 point, shot at 6 yards through the neck. It worked, and I wouldn't hesitate to use it on bigger deer at a greater distance.

For a 300 Win. the 130 grain Barns at middling velocity works well but I ended up going back to full power loads as the recoil was not that much different. Any medium weight bullet that splits the velocity difference between the 06 and the H&H will work well. Many of the starting loads will be in this or close to this range. Keep adding powder until you get the accuracy level your looking for.

At or just slightly above 06 velocities most cup and core bullets will perform well no need for anything expensive. Any of the middle to slower powders should do. Those in the 4350 to 4831, R22 range are a good starting point if not overly reduced.

For reduced loads I check the Lyman manual and see if the same powder is used for both cast and jacketed bullets if so then you know the safe range for that powder and have a rough idea of velocity.

I own/have owned numerous rifles in 30 caliber. The 300 H&H is one of my fav's.

Here's mine




It started life as a Rem. 700 Custom KS in 375 H&H and was re-barreled to 300 H&H and accurized by HCR. I gave it a Krylon Webbing spray, rattle can paint job.


The gent I purchased it from had several boxes of factory ammo.


The 180 gr. Barnes TSX are killers........





However, my go to load for the 300 H&H is 180 gr. Nosler Accubonds over 69 Gr. RL-19, Fed. 215M primers at 3.580" OAL




It is a porker perforator.


JAPPFT,

personally i dont think you have to search or think to much about it, downloading something down to around a 30.06 or thereabouts.

I can tell you this, few years ago buffalo hunting in colorado.
partner had a 300H&H and he was running 180grain i think it was failsafes in it.
at about 100yards he popped a bull. It didn't go anywhere.
we didn't put it on a scales but estimated live weight around 1400pounds or so.
Upon opening it up, it blew the top half of it's heart out.
