Painless load development (mine)

[Mw01313]

Wish I'd found this method earlier. Burned up a lot of components adjusting charges by .1s of a grain and incremental seating depth changes. On my 2nd rifle now. Much easier.

Tried this out with my 338 RUM and the 250 Norma GTX the other day. Checked for pressure since it wasn't a published combo and loaded where I thought I was safe. 5 shots at 100 yards and adjusted the scope. Moved to the 300 yard steel (furthest my local range has) and was stacking shots on top of each other.

I'll verify with 10 shots at further distance, but I think this combo is going to work. For reference, that's a 1" square on the target.

That's a pretty spectacular group from hammer of a load. Well done!

It's funny how traditional ideology would have you trying to excuse that 1 as a "flyer", or "pulled", etc. I look at that group now and think as long as you keep breaking shots clean like that, that's probably just gonna fill in and be a damn fine load. Especially out of a 338 RUM! Lol.

So true. I still call them “flyers” but don’t excuse them as such anymore. It’s just the group and how that gun shoots with that particular combo.

F***in fliers! 9 shots into like .4" and one just had to shit the bed. I honestly think that may have been a bedding thing, as this was from a Tikka action in an unbedded and undertorqued factory stock and being shot bare muzzle. But yeah, still part of the group!

Heck yeah, and still a killing shot 99.9% of the time.

Form's method is going to drive the OCD guys over the edge!

I'm OCD as hell and it's actually been a stress reliever. It absolutely drives the OCW believers nuts tho!

Lol. I've been reloading since about 1988. My method is similar to Forms. Anymore I want to spend as little time at the range as possible.

Thanks! I definitely enjoy shooting my 223, 22 Creed, etc but there’s just something fun about a big boomer haha.

Thanks! I agree, in the past I probably would be trying to explain that away. It just is what it is. I’m excited to stretch this out on steel next week to see how it does.

MRC 6cm, 93gr McGuire Copper Rose. Same load as the 95gr TMK- 43.5gr H4350. Seated boattail to the neck/shoulder junction.





10x, 100 yards rapid fire-




We’ll see how it does at distance today or tomorrow.

Formidilosus, I am really glad to see that others are using this method. When I started out reloading I didn't have the time to waste driving back and forth to the range to run ladder's or OCW test. So after lot's of reading and understanding pressure's I started loading.. All of my very first reloading were half moa or better out of my bang stick and my brother-in-laws .. My brother in law wanted me to load up some for his 204 ruger and I picked 2 powders Staball Match and Tac loaded up 20 of each the Staball Match ran 20 rounds with a SD of 3 and most shots where identical velocities at 3699 fps. and under 1in group .. The tac was ran 3740 fps and don't recall the SD wasn't bad tho and was a bit over 1in .. My brother in law and nephew was amazed that I was able to load up ammo that good without lots of testing... Thank you for sharing your method.


God Bless

Here’s another one. New 22 creedmoor barrel. I did have to switch powders. It did not like RL26…1.7” or so not quite what I wanted.

Made a powder swap, work up to pressure, back down a grain, and two confirmation groups.




Just before that barrel I got a new 6cm going. It did not really like the first bullet I tried (106 tap). Tried two powders with mediocre results.

Swapped to 109eld, worked up to pressure with RL16, backed off, and done.

Sometimes you need to try a few combos of powders and or bullets..other than that no tinkering needed.
