Anybody have any data?

Barnes # 4 shows nothing

Barnes # 3 shows nothing

Hodgdon website shows a max of 75(c) grains but that is for the 270 grn TSX. However, that load is only operating at 43000 CUP and the spec for the 375HH is 53000 CUP. Additionally, the load only has a velocity of 2465 fps. Most 375 HH 270 grn max loads are 2650+. In fact all but one of the loads on the Hodgdon site for 270 grn TSXs are sub 2550, so the data seems overly cautious.

I was thinking that about 70 grains would be a and estimated max for the 300 grn TSX. I came up with 5 grain reduction by looking at the Barnes #4 manual and seeing what the max charge drops were between 270 gr and 300 grn TSX bullets for a series of powders and it runs about 5 grs.

So I was going to start at 65 grains and work up in 1/2 grn increments stoping at 70.

What has me scratching my head is that the
Hodgdon website shows 81.5(c) as the max for a 300 grn sierra. Now I recognize that the TSX is longer but I would not expect the need for their to be a 10+ grain difference in max or estimated max beween a TSX and standard bullet.


Thoughts?

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Can't really say - haven't tested the TSX yet in my .375 H&H.

I have used 80.0 gr. H4350 with the following bullets: 300gr. SGK, 300gr. Partition, 300gr. Horn. IL RN, 300gr. Horn. Solid, 270 Horn. IL, 235gr. Speer.

80.0gr. has done well for me for anything non-Barnes. I think you're on the right path: start at 65 and work up to 70 (I'd got to 72.0 or 2,500 fps, whichever comes first). I'd also work with 1 gr. increments, but that's my personal tendency.


Regards,

Robert

Barnes #2 doesn't have H4350 either, FWIW.
Tried some IMR 4350 in my .375 Wby -- suggested start load was 72 grains. (Max H&H loads were a good starting point for .375 Wby, so your 70 grains may be near the top.)

I use IMR4350 for powder in my 375 H&H AND it gives me 2668fps with the 270gr bullet.

You won't get enough 4350 in the case with a 300 grain Barnes X.

I think you will find the big difference in loading is simply because the powder won't fit when the Barnes X is used.

I would be using Varget or Reloader 15

Edit: Just looked at the Barnes site and they list with their 300 grainer for Re 15

RL 15 65.0 2403 71.5 2589 101 The 101 is 101% of case capacity so very slightly compressed.

I use 76.5 of the same and it gives me 2550 with 300 gr. Hornady Interlocks and A Frames. Every load I've ever seen comparing the two powders, it takes a bit more of the Hodgdon than the IMR to achieve similar results. I'd start at 71 or 72 and work up to 2500 +-.

Mike,

It may not be that far off. The nosler manual shows 75 grains as a max load for IMR 4350. H4350 usually runs about a grain less. So call it 74 grains for H4350.

Since the TSX is longer than a partition, I could see a 4 grain reduction.

Now I am not saying that I would jump right in at 70 grains but it may be in the right area.

For RL-15 I would only go with 63.1 grains. That will give you 2500 FPS. Pressure at 53610 and a fill of 92.1% capacity.

I know.

But what I an saying is QL has 70 grains of H4350 doing 2500 and Barnes is only getting 2589 with 71.5 grains of Re 15 and Re15 is way faster than H4350.

Hopefully Mike will chronograph the 70 grains of 4350 and 300 grain Barnes. I reckon it will be lucky to make 2300 f/s Smiler

Can't see it. Last time I did a 375 was with Re 15 and 73 grains with 300 grain Nosler was just over 2600 from 26" barrel

I reckon with 63 grains the bullet would drop out the end of the barrel and roll along the ground Big Grin

Yep, allowing for bullet length I reckon 70 grains will fall out the end of the barrel Big Grin and the primers will look like you fired a 30/30

Mike McGuire,
I agree the 300 grain Partition will give you 2603 with 68 grains of RL-15. And within safe pressure.

That same charge of RL-15 and the Barnes 300 Grain TSX is WAY OVER MAX PRESSURE and 2665 from a 26 inch barrel. According to QuickLoad. I won't be using that one!

I used 73 grains and just over 2600 in 26" barrel. 76 grains was 2850 with 270 grain Hornady. Ohler 35

So QL is saying Barnes data of 71.5 Re15 and 300 X is through the roof in pressure.

According to QuickLoad it is almost in orbit!
QuickLoad gives the max pressure for the 375 H&H as
62366 psi, 4300 bar.

For a load of RL-15 71.5 a 300 grain .375 Barnes TSX, product #37558
In bright red box it says,
Pressure (Pmax) 77997 psi, 5378 bar, 104.4 % capacity.

I don't have a Barnes manual. All I can quote is the QL program. I've never used a 300 grain Barnes TSX. I am a big fan of RL-15 and use it as often as I can.

I love this. Being able to discuss stuff with some one on the other side of the world! Too cool!

Mike, I went to the site and if that was all I had to base my reloading on, I would probably try the lower end. That being said, after looking at QuickLoad, which is usually right on for me in the velocity and pressure department, there isn't any way in God's green earth, that I would stoke up a 300 Grain Barnes TSX with 71.5 grains of RL-15.

Now a Nosler Partition, that another story!

Best regards,
Rusty

But I will bet 4350 falls out the end of the barrel unless the velocity is over read by a Chrony.

Mike M.,


I have found on one other occasion that barnes data can be off.

I loaded AA2520 for a 308 Win. Barnes listed a max load of 47.5 grains for the 180 grn TSX. I was in a hurry so I fgured I would start at 46.0 grains. 1.5 grains or just over 3% under max.

I had to beat open the bolt with my shoe. I backed way off and worked up and I got pressure signs at 44.8 grains.

Prior to the publishing of Barnes #4, Barnes would state that because of the grooves in the TSX you might be able to exceed listed charges in Barnes #3 by 1 to 2 grains.

This particular 308 Win 180grn AA250 charge is a full 3.5 grains above the #3 manual max load.

Interestingly, I can find no other comaprison in manuals #3 versus #4 where the #4 load exceeds the #3 load by 3.5 grains.

Additionally, many load comparisons between #3 (x bullet) and #4 (tsx bullet) show little to know difffernce in max charge weight.

I should get to the range next weekend and will bring my chrono.

While modern loading data is on the mild side, I agree with you on some loads being are over.

Hodgdon has 113 grains of Retumbo for 180 grain 30-378 and that is primer popper load.

Well, I got to the range with my chrony...

COL was 3.6 Barnes 300 grn TSX

Here are the results for H4350

Grns - Avg Fps 3 rounds

67 2238
68 2263
69 2296
70 2318

For Varget

68 2501
69 2537
70 2573

No pressure signs with any load. The 70 grn H4350 load was 1.2 inches for 3 shots.

The 70 grn Varget load was @ 1.05 inches for 3 shots.

For H4350 - I suspect I could go to 70.5 grns with no issues and would be at about 2330 fps.

For Varget - I will probably try 69.4, 69.7 70.3 and 70.6 to see if I get any improvement in accuracy. 2550ish plenty of velocity for me.

What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

As it has already been said, for monos or mostly monos, there isn't enough room for 4350. RE15 runs pressures up pretty fast with those same bullets. I have found that RE17 is the "go to" powder when you want 4350 type velocities/pressures but there isn't enough room for 4350. Either that or try H414/760.

What we really should do is all get together and have a "powder swap". We probably all have some types of powder we won't use up in our lifetime.

Mike,
not in the least .. though the 69gr makes over 2500, and you can adjust your seating depth . and with TSX, setting them at -.065 and making them SHORTER usually results in both more vel and better groups.

i would start with the 69 just so i didn't create more pressure than i want
