Home Forums Hunting & Shooting AR and Tactical Rifles H4895, Talk me into it....

I use 4895 in the 5.56, but IMR-4895. Velocities are better that H4895 and some bullets just like it.

Everyone has their preferences, but I've never been able to do anything, in either a bolt gun or an AR, with either version of 4895 that I couldn't do better with something else.

Put a hat on, Texas Sun getting to you… 🤪 I tried all the powders everyone talks about for high power. Varget, RL15, 8208, H4895, and everything else in between. I never achieved any ground breaking velocities everyone talks about 2800-2900 fps. Only powder that gets me anywhere near 2750 range is AR-comp (18 inch barrel). I have messed with your all time favorite N540, like I mentioned to you yesterday I bought 4 more lbs of it. I will say again my H4895 load I use is for reduced yardage xtc matches. My 2495 load with 75gr ELD-M is close to 2800 i think 2785 if I remember right. But as of now if I had a choice it be A2495 or AR-Comp. N540 I need to mess with more.

I really don't think that velocities above 2800 in an 18" barrel with my standard bullet being 77 SMK's is possible at pressures that I want to be at with any of the powders discussed.

2750-2775 in an 18" barrel makes me happy if I can get decent accuracy form any given load.

On your recommendation, I'm going to try the AA 2495 as that seems to be available pretty regularly & at a decent price, given today's market.

I have not been able to get any VV 540 or 140 in quite a while, but have a fair amount of 540 on hand.

Alliant 2000-MR has also worked will for me & get high velocities, but takes a lot of powder to get there & I haven't seen any of that available in a long time either, nor AR-Comp. And all the Alliant stuf is crazy expensive.

I was lucky a yr ago and scored an 8lb jug of AR comp. I’m using 24.8gr of 2495 w/75gr hornady bthp and this load shoots extremely well in 3 of my AR15’s. Same data can be used with 75gr eld-m seated at 2.495-2.500 yes single load.

My experience as well although I use 24.5 grs. with the 69 SMK for an average of 2,810 fps from an 18"/8 twist barrel. That load was one Glen Zedikar suggested in an article and it works very well for me.

24.0 grs. works well with the 77 SMK in that same barrel at 2,725 fps. (Over max, work up)

Not that I'm aware of. I can see all your posts. But I'll check and reset my stuff

I could see your posts fine, but it did say something about unignore user, not a clue, so I clicked that. Maybe its different on your end now?

There was a note about pressures. I've had mine run for pressure with N540. I don't recall the exact results but lets just say the 52 load and the 80 and 90 loads were done, and they were somewhere around 60 IIRC. Which doesn't bother me in the least.

That said to play with N540 your re going to have to get it hot. It doesn't like mild or medium loads.

Lets talk about pressure vs speed. Just so its out there. The only barrels I worried about a certain speed on were 20 inch tubes. And there was never a factory tube in that bunch. All custom like shilen, Krieger, Rock, Pac Nor, a couple of junk Douglas that never got to speed, and one blackstar.

Shot with state team shooters. And quite a few others that could verify the N540 stuff. One of the La Berge family of long range shooters too. In fact he is the one that told me to open the powder measure a bit more.

To the end I ran odd groove Pac Nor 6.5 twist tubes but ran LOTS of 7.7 and 7 twist Krieger etc...

Moly all bullets.

Only LC cases.

Ran only 77 SMK. 75 H bthp couldn't deal with the base pressure. 75 amax were fine but not fast. Some of the mag length 70ish bullets have a long bearing surface. IE they can't get to the speeds an 80 with less bearing surface could.

So some bullets simply won't run fast.

Can or did powders change. Sure its all possible.

We ran an Oehler 35P chrono at about 15 feet.

I don t' know if I can find an7 80 moly data and if I did it would all be JLK. 80 SMK never did all that great for us. 80 Bergers were ok but a bit slower than JLK with lower BC

I did pull some 90 loads apart to verify powder, that data is in Delta but was either 25.7 or 25.9. With a 90 JLK seated out long single load.

4895 produced fine accuracy mostly way back when. But it was sure slower than we wanted.

For general non match work that wouldn't bother me a bit.

Varget was ok for speeds, 2850 with 69s maybe close to 2900. RL15 never did much for me.

The above is simply for your info.

Dont' discount primers either, though we finally were down to more or less R7.5/CCI M41/450 and CCI BR4 and those did all we needed, but primers can double a group size or cut it in half and they can affect velocity also.

And recall all my data is 2005 or earlier data... I've no clue what happened since and thats almost 20 years... but according to the tiny knot I shot with a 90 ilk load in October the load still works.
