Lefty, what kind of velocity are you seeing over RL-25?

Thanks!

haven't chrono'd this pill yet, but ballpark from other 150's and this combo shows 3300 fps. I'll get more done if this god forsaken weather ever breaks. I haven't even really played with the 7rum I bought over a month ago... only a couple of test loads to make sure it wasn't a blunderbuss. I'd normally have it rung out and a hundred+ loaded by now.

Coop & Lefty
Thanks for the info! Results from both recipes sound great. Will give them a go and keep you posted.

Thanks Lefty and keep us posted... If I can't find a happy place with 168's or 175's the 150 gr. LRAB will be my next and final stop before rebarreling my STW. I've got a lot of stuff loaded to test now - I just need some more daylight and decent weather. I don't have and haven't been able to find any RL-25 around here but I have seen RL-33 on the shelf. Thinking I better pick up at least a pound of it to play with. It would probably be good with the heavier pills, but I haven't heard of too many STW guys trying/using it yet?

Boy, since the STW first came out, some awesome powders have came down the pike, and for the longest time, I was a die hard RL22 user, and swore by it, even if it is temp sensitive. The H1000 has always been good, but when the RL 25 came on, that changed everything for me, except in one gun. My standard load is now,


82.0-rl25-145LRX
215 GM primer
A Square brass
COAL is 3.688. ( Remington Action )
Coal is 3.640 . ( Winchester Action )
1-9.5 twist
3440 fps

79.3 - RL22-140ct
215 GM primer
Winchester brass
Coal - 3.675
1-9.5 twist
3389 fps

81.5-RL25-140 partition
Winchester brass
215 GM primer
3.640 COAL
1-9 twist
3377 FPS

The formulas work for me, but were worked up to, not just assumed.

I have a Cooper model 52 and I worked up with rl-25 145 lrx. 80g was OK but 81 melted the brass a little around primer pocket. I just want to say make sure you work up.

Hey guys I have a coal question for you guys, hope you guys can help me with this. I just got my new barrel in and I ran a dummy round in and got 3.878" coal. Now all I can get into my mag Box is 3.823. Now how much of an issue if I'm going to use berger 180 vlds? That's starting off at .055 off the lands and I hear vlds like to be much closer than .055. If any insight on this I would appreciate it.

Load it at 3.640ish ........thats where its gonna get sweet at

 

[Stickerflicker1]

That's like a 1/4" jump off the lands. Nothing wrong with it that far away?

If it is one thing bean knows, it's the STW!!!! Try it.

If you get good accuracy it is a moot point what the jump is. It is a given that less/no jump will make it easier to get an accurate load, but with some calibers like my stw and 7rum is really isn't possible or desirable to load to the lands. You want a bit of bullet run to smooth out your pressure peak. I'm at about .4" run to the lands with my 7rum.

Senior moment???

I've loaded .270 for perhaps four decades, and .30-06 for three.

Am I correct that 4831 and 4064 are possibly too fast for the STW?
