243 reduced H4895 loads

Does anyone have any experience using 60% H4895 loads?


I am looking to start loading an 85grain bullet to about 2400 fps and then work up to accuracy. I calculated, based on the difference between the listed min and max that there is 134fps per 6% reduction in weight from the max listed.


By my assumption, about 24.5 grains of H4895 under a 85gr .243 spitzer should yield about 2420-2450 fps.


Then I read on another forum some guy was using 28-30 to get 2400 fps. Causing me to wonder if the effect is actually linear as I was calculating. I don't want to start at say 1,800 because my assumption was wrong. I need about 2400 for expansion of the bullet.

The deer didn't disappear.... the 250,000 guys who used to walk around and make the deer move did.

I don't have any experience with the 4895 reduced loads but heard that they work as advertised.When my son started at 7,I loaded 95gr ballistic tips with a reduced load of 34.5gr of IMR3031.There was virtually no felt recoil and we killed 5 deer with that load that year,including one of the biggest bucks I ever shot.

BTW, you can also use Trail Boss.

It won't be linear, I can tell you that much. I'd look for some reliable reduced load data to start with.

Take a look at this site. They are talking about reduced loads using Blue Dot:

I'm not sure an 85 gr bullet at 2400 fps is a great objective for a hunting round but I'm sure it will get the job done. It is not the way I would go personally.

Anyway, I have next to zero experience loading for the .243. I believe that 24.5 gr H4895 is well under 60% case fill and won't get close to 2400 fps. Quickload suggest more like 29 grains. Low fill, low pressure load predictions can be way off, however. I use Varget in the .260 for my daughter with 120's. I'm around 85% fill and 2550 fps. If 2400 fps is your goal, H1000 should get you there with a respectable case fill (around 90%). That said, I'd be looking to load 100's at around 2600 fps if I had a desire to shoot reduced loads in a .243. My daughter's .260 load has very mild recoil in a very light rifle. 100's at 2600 would recoil even less. I don't see the need for anything less than that. I understand that piles of anecdotal evidence can be provided in regards to the effectiveness of super light loads. I just don't see the point.

I saw Trailboss mentioned. If you go that route, I seriously doubt you will approach 2400 fps. I'd expect more like 2000 or less.

That sounds like a better plan to me. You are probably around 2800-2900 fps with that load.

I have experience using IMR 4198 in .243, 7/08, and .308. 21 or 22 grains with a pea size ball of polyester filler pushed down on the powder topped with a Sierra or Hornady "single shot" pistol bullet. Gives 2200 fps and kills deer extremely well and is sub 1 moa in a good rifle. No recoil. Great for kids or some one recoil sensitive.

....give me a couple days and I'll pm you. I have loads for H4895 reduced and H4350 minimum that I run 2 suppressed .243 s with. I try to stay between 2500 and 3000fps for my RRA Pred HP, Savage 11 and Rem 700(non-suppressed)

..What rifle are you loading for?
