Rokslide Special 223 recipe

Shamefully, I haven’t reloaded yet. I ran out of time and money to buy the equipment. I found that Hornady Black that shoots 75BTHP less than 1.2 MOA and it’s cheap, so I’ve been shooting that until I actually start reloading.

It's spendy to get started. Thankfully I have a press and a bunch of other stuff otherwise I'd be in the same boat. Just getting geared up to hand load a new cartridge isn't cheap. It's way cheaper than my 300wm though.

Perhaps, but I'm not going to mess with it. VV N135 and N150 both give good velocity and shoot better in my rifle, as well as burning cleaner.

I also got pretty low velocity from H4895, so have to wonder if the pressure curve of those two powders work better with longer barrels.

I burned up the pound of AA2495 for target practice. The H4895 is being used for low velocity loads.

What charge weights, brass, bullet combo did you try with h4895? I've found it to be about tops for velocity as far as single base powders go with heavies.

3rd groups on their own show little. 3rd groups using the same type of point of aim so you can generally overlay them tells you something more useful. Realistically he has a 12shot group on that target spanning 1.1gr of powder charge that all shot well as an aggregate within 1 square. I find that statistically relevant during load development.

I’d use that data to confidently load up 10+ rounds in the 24-24.3 range to validate now.

If he had a single good 3shot or their point of impacts varied relative to each other then I agree it’s not very useful.

Everyone does load development a bit differently but I find 3-4 shot groups quite useful. Right now I’m developing a hunting load for the 75gr Speer Gold Dot in my .223 Montana. These bullets are extremely hard to find so I want to conserve what I have. I’m working with 5 powders. In 4 shot groups at .5gr intervals I can shoot 4 (or 3) shot groups and tell immediately if that powder charge, for that bullet is going to be useful. Testing 10 loads with 4 shot groups I saved 10 bullets. That’s a couple of hunting seasons if I do my part (2 deer per season if I draw a doe tag.

Yesterday I eliminated 3 powders and found 3 loads that are near minute of angle shooting only 40 rounds. Today I’ll pick my load shooting those best 3 loads to eliminate shooter error. I can see shooting large groups (10-30 rounds) to determine ultimate accuracy potential for long range shooters. After today if I miss a deer at 200 yards or less (99% of my hunting in the Adirondacks), it’s the Indian, not the arrow.

The practice I really need is field position shooting, even though I love shooting off a bench. This type of load development won’t keep me from reaching my full potential. I’ll do that shooting with cheap bullets and older components using loads developed the same way.

My method might not be statistically significant, but I eat a lot of venison.

I hope you all have a successful hunting season.
