260 gr 30-06 load data

I know there isnt any standard loads for bullets this heavy. I talked to Badgeredd and got some weird quickload numbers i would like to run past you guys. I am looking to find 1700-1900 fps as a max but everything he gave me was REALLY slow, the data also just doesn't make sense to me.

Here they are:

27 gr 2400 @ 1400
IMR 7828 54.5 gr @ 1500
RX 22 57.5 gr @ 1600
RX7 56.5 gr @ 1600

I was expecting something like 50 gr of H4831 for 1700-1800. Any ideas gents?

Did you ask him to run slower powders? I, too would be thinking something around 4831. Play with the burn percentage numbers in QL with different powders in the velocity range you seek and see how slow you can go efficiently. Also look to load density figures with your measured case volume/grains H2O.

I asked about 4831 and he said it was worse. I have never seen the floor fall out on velocity like that from 240's at 2300 to 260's at 1600 just doesn't seem right.

Case fill:

7383 is 106%
RX22 is 102%

27 grs. of 2400.............Not me ! !
I once knew a friend that stuck a bolt and blew a
primer at the same time with 25 grs. of 2400 with
a 180 cast in the 30-06.

those don't sound right at all.
57grs of a not too slow powder 7828/rl-22 isn't gonna give 1600 fps.
I tried about that much 7828 under a 314299 [with a tight fitting nose] and for sure the recoil was not indicating 1600 fps.
2800 maybe [recoil is comparable to 48 grs of 4895 under a 150gr bullet] 1600 fps no way.
I don't think I even hit paper at 100 with the load but the grey poof at the muzzle and antimonial wash was impressive.

I think I was expecting about 2300 fps, but the tight nose fit was bumping the pressure rapidly and I ended up pulling the rounds down.

Thanks guys, i think i am going to try a 16 gr load of 2400 just to get a base velocity then walk up with it. I may also try a load with 4831 at around 45 gr with a dacron fluff and check velocity.

I am not going for burner loads, just a nice heavy hitter at moderate velocity.

that 4831 load should be close to 2400 fps, it is in my 308. [with a 30" barrel]

I started at about 40 grs.
4831 has an off again on again track record for many of us.
it didn't start cleaning up in my 308 until I got to about 44grs, I bumped it along to just over 45grs in .3 gr steps.
the clean-up [44ish] was indicating the pressure was in the 50-k range.
before that it left a ton of trash in the barrel.

in my 30-30 it is just fine at 34 grains, giving a couple of clicks over 1800 fps but the load density is about 95% in that case.

out of your powder choices above.
I'd probably back the rl-7 load down and work with that depending on my end goal.
22 grs or so should be close to 1900 fps off the top of my head and be pretty manageable to work with from there.
it's a stable powder down loaded, and is just fast enough you might get away without a positioner.

I have IMR 4198, could i run with about the same load there? RX7 i will have to get a can of but i do have it local.

Tom cut this one, I have to admit it is a VERY nice mold. He is also one of the best for "one off" molds. I would have had to order cherries and wait a month. This came in 9 days.

Does it come with lead and an eraser? That thing makes a 6.5 bullet look short.

Tom does some nice work, doesn't he?

You actually got a snort of laughter from me... lol

I have one of his older molds, bought it 2nd or 3rd hand, this is my first "new" mold from him and it is very nice.

I have a feeling i am going to use BLL on the nose of this guy, not sure if it will be "grabby" on the riflings but BLL should fix it.

I will, i am going to get a base with 16 gr of 2400 then try 21 gr of IMR 4198 and move to 4831 with a filler.

I only want 1800-1900 so it should be easily obtained.

4198 or 4227 would both get you there as easily as the rl-7.
you might just end up at 18-19grs of the 2400 and be happy too.
that boolit would lay some straight up smack down on anything within 150yds at that velocity.

make sure to do the heat cycle, cool down, short runs thing.
it will pay off big time in 3-4 sessions.
Toms molds generally do their best work on the cool side of the spectrum [cool alloy temps and the mold just hot enough to show some light greying of the boolits in patches] for me.
I can focus in on those little patch spots and keep things in that zone for a good 100 pours without getting tired.

Thanks for the heads up, now for bets...

When it hits a deer will it bend and break or mushroom like normal?

I want to say bend like spaghetti and mushroom oddly.
