Cast in BLR .358 win

[tgator]

Been thinking I should shoot this rifle more often than I have. Before I start investing in moulds I cerro safed a chamber cast and bought a box of Beartooth 210gr LFNGC sized to .358 to fit the chamber well. Seated to crimp groove they fit magazine and function well through the action. Can I start with a load of 16gr 2400 ? My goal is to work up a deer round of 1800fps and a plinker of about 1050 - 1200fps. with 150 - 180gr handgun boolits. Can anyone offer advice on using 2400 for the deer load? I'll try faster powder for the plinkers. Thanks in advance!

I am thinking for the deer load, I would try a slower powder.
Something like 3031 or 4064.

Would something along the lines of 4895 be in the right burn rate? My Lyman #3 only shows fast powders that won't get me to around 1800fps. My others start at 2200fps for "J" types and I'm not sure if I can interpolate down enough. The 60% rule for 4895 would get me in the ballpark? I have quite a few powders, but no 4064. would a filler be needed?

I would shoot those boolits first, and see what they do. I have to size to .359 in both of my .358 Wins.

[runfiverun]

cut the load one more grain and use a dacron filler reduced 4895 loads do better with a filler.
i shoot rl-19 in my 358 win with the saeco 250gr boolit sized to 358 i have worked up to 50 grs but stick with 48.5 as it is more accurate after a few shots [might just be me handling the recoil longer]
others should be along shortly with many other loads.

[tgator]

I would like to hold velocity down to around 1800fps. Your loads of RL-19 seem they should be above that. I will work up a ladder of 4895 w/filler starting about 22-23gr as soon as I get a warm enough day to set up the chrony.

Would I be better off with a slower than 4895 powder for 1800fps?

+ another on the 4895 with the dacron filler. Also If you decide to cast your own look seriously at the RCBS 35-200-FN. It is an excellent design and works well in short necked .35s like the .35 Rem, .356 Win and .358 Win.

I would say IMR 4895 would be about perfect. Note that in any burning rate there are MANY powders that are virtually identical.

I cannot find any recommended loads for that combination using lead bullets.

My Lyman #4 lists 204 gr lead bullet No 358315 with 18.5 gr 2400 @ 1600 fps and 25 gr 2400 @ 1979 fps.

I would try that 18.5 gr load first and work up one half grain at a time.

They list the CUP pressure on the 25 grain load @ 34,000 You are not going to get in trouble at those pressures. The .358 Winchester is rated for 50,000 + CUP.


I am not familar with your 60% rule but I have been using jacketed loading data with cast bullets for decades. Starting with something less than the recommended starting loads because even starting loads are frequently faster than I want.

And NO you don't need filler unless you get into some of the single based fast burning powders.
( edited - Obviously I seem to stand alone on this issue. )
If you do use a filler, a piece of advice: Don't shoot into the wind.

For you plinking load, you should try 2400 or Unique. You don't need filler with either of those.

My rule for when to use filler is:

If I can't make it shoot without filler, I change the powder.

Good Luck.


PS: with reduced charges in a case that large BE VERY CAREFUL YOU DO NOT THROW ANY DOUBLE CHARGES.

Charge all your cases at the same time. Set them mouth up in a loading block. Place them so you can see down into all the cases at the same time and shine a flashlight into them. A double charge will jump out at you like a red flag. - So will an empty.

200 gr cast in 358 is a great boolit. 38cal pistol bullets are fun for pest control too.

The 60% is from the Hodgdon manual for 4895. It basicly says take the max charge shown for the cartridge and reduce by 40% for lighter loads. No other powders than H4895.

Thanks much for the info from #4. I need to update my library. I prefer not to use fillers if at all possible. Would a larger charge of slower powder get me to 1800 without fillers?

Yes, but I can't find a recommendation for your powder.

[runfiverun]

yeah they usually will.
fillers are best suited to the medium speed powders h-322 to the 4064's.
most all of my best hunting and most accurate target loads are built with medium powders and a filler.
faster powders don't usually need fillers but it sometimes will help accuracy.
the slower case filling powders don't need them as, well,, the case is full.
the trick is to find one that fills the case burns clean and gives you the velocity you want.
the rl--19 will be far over the 1800 you are looking at, but going to an even slower powder would fulfill the need.
the 35's will give you outstanding accuracy with no problems over velocities that the 30's will don't be afraid to push the velocity up on them.
manipulating the alloy with 25% soft lead a smidge of tin and waterdropping will give you an excellent higher velocity capable boolit, but one that works very,very well on deer and bear.

Any thoughts on trying a full case of WC872? I know its dirty, but the heavy (compared to thirty cal) boolit may help it burn cleaner. Guesses on velocity?
