Hornady .458 300gr HP’s

I ordered 3 boxes and they arrived yesterday. I got an additional discount by using my birthday discount. It's a great bullet in the 45-70 for WT deer.
That’s how many I ordered too. I got a couple boxes of 300gr XTP Mag’s for my Ruger MPR 450 Bushmaster as well.
They sure do work on deer just like you said. I load them both to a 2050 fps load and can switch between the two without a thought. Same Nikon scopes on both really does make them interchangeable.
 
My first 45/70 hand load was the Hornady 325FTX and it shoots reasonably good and has enough for deer or black bear. But being a little bit of an old school guy, the plain 300 HP is right up my alley. I was looking for recipes on the 300 and a bit frustrated as the recipes were all over the place. Ended up doing a short ladder with the HDodgson recipe they had for SPH 300 which starts at 55 grains of H4193.(WLR primers)
Here’s the ladder results.
Load. FPS ave. Sd
55. @ 2298. 21
55.3 2321. 5.4
55.6. 2357. 4.2
55.9. 2361. 4.1
56.2. 2367. 6.3

That bullet and primer while stout looks really well behaved.

The recipe called for max load of 60grains
At 2,424fps

I do have the 22” barrel on my 1895…which might explain the great Velocity.. it was 75f during the test.

Now I have to decide if I buy some Sierra ProHunters in their 300HP Looks a little less tapered than the Hornady. I can load the Hornadys at 2.595” and work the action. Limiting factor is ejecting a loaded round.

I have a second ladder loaded exploring seating depth with this Hornady 300 grain.
I started with 200 bullets, so have 170 left after the 2nd ladder.

BTW, loaded the 325’s with RL7 and it’s accurate around 2000fps with 49.1 grains.

That 55 grain load with H4198 is pretty stout even for a starting load. That’s what I started with was H4198. Still have 4-5lbs. I backed it down to 51 grains and went to IMR4198 and 2050 fps. Plenty for deer and my shoulder.
 
Fellow I met in bear camp about a year and a half ago dropped his black bear very nicely with one of the 300 gr Hornady bullets from his 45-70 Marlin 1895 Guide Gun.

Excellent penetration as well as expansion. Fairly short range shot but I don't remember the specifics.
