235 gr. 375H&H W748 load data

[Monsai52]

I'm looking to load up some 235 gr 375H&H loads for some fun at the range. I have a good amount of W748 and would like to use that if I can, but I can't find any load data. From it's burn rate it appears that it would be a decent powder to use. Does anyone have any load data or experience using W748 with a 235 gr. bullet?

Best regards,

I don't, but there are several people on here that are very generous with their time running load data for other, I suspect when they log on tomorrow, someone will be able to help you out. Best of luck.

I,ll get down to the garage today and see if I still have some data you can use

 

[Monsai52]

Thanks! Really appreciate it.

I could find no published data but its burn is a bit slower than IMR3031 and there is plenty of data available for that powder. Like you I think it should work fine and would not hesitate to start by using the 3031 data and carefully work up a load. One other suggestion is to call the tech support line at Speer and ask them. I have done that with Sierra and they were very helpful. Good luck.

Same here best load data I have for 235g bullets are with Win760 sorry

I just thought about something, I seem to remember reading about a PH on the forum that uses a 375 loaded with 235s.

 

[Rob404]

If all else fails, moving up to 250s will get great results

 

[Monsai52]

Thanks for checking! Good suggestion to check with Speer.

Best regards,

check of my winchester manual shows 748 but they only list in the 375H&H for 270 & 300 gr bullets. At an NRA convention about 40 years ago I talked with the Winchester rep and he said that in the 375H&H they used IMR4064, which is just slightly slower than 748, so considering the 235 gr bullet is lighter than the 270,300s, it would seem that 748 would be a very workable powder for the 375H&H.

Hello Monsai,

As reference, Barnes list for 235 TSX bullet in the 375 H&H

W748 Min 76.7gr 2805 f/s - Max 85.2gr C 3051 f/s
H4895 Min 67.0gr 2732 f/s - Max 74.5gr 2946 f/s
IMR 4895 Min 71.1gr 2755 f/s - Max 79.0gr C 2998 f/s
Varget Min 70.7gr 2736 f/s - Max78.6gr C 2973 f/s
RL 15 Min 73.4gr 2757 f/s Max 81.5gr C 3001 f/s

In my experience with W 748 vs. R15 in my 375 and my 9,3x62, both great powders for them, in the lots I have, W748 is 4 and 2 gr slower, respectively, than the R15 for practically same velocities, being all other things the same.

Good luck

Be very careful using Barnes data for “regular” bullets-woodleigh 235 for example. I use both Barnes and woodleigh 235’s but in a .375 WBY. Barnes gets the nod for accuracy but that’s just my rifle!
I’ll echo the above advice-contact the manufacturer of your chosen bulllet and ask them for their recommendations. I’ve found that e mail works best. Good luck, I know why you are using that powder but it doesn’t seem to have much popularity in this particular loading. . .

 

[Monsai52]

Thanks for all the information and suggestions. The 235grs that I have are Speer, so I contacted Speer to see if they had any 748 load info. No 748 data, but the gentleman that I spoke with did agree that due to the burn rate it should be decent choice for that bullet.

I'm just loading these for some fun range/practice loads, so not looking for anything hot, so I'll probably start some load development in 70 - 72 gr level and see how that works.

Best regards,

Hi Monsai,

One more thing. In my experience, data for R15 can be used for W748 in the 375 H&H, 9,3x62 and similar cartridges.

Thanks, I'll cross check with R15.
