22-250 69gr tmk load advice please..

[Dave_45]

Hi folks

Rifle is as follows
1/8 twist ,26 inch barrel.
I've finally gathered up enough 69gr tmks to justify working up a load ...

I plan to make use of the barrel length, and get em moving along ..

Any powder suggestions for me ?

My brass will be lapua and primers large rifle CCI

Thanks

No, the manufacturer does not let you know the secret recipes which will yield 4,000 fps MV and 0.1 MOA groups.

This devine knowledge can only be passed on through forums where load data is derived from computer programs and speculation!

I run 69gn TMKs in my 22-250 Bergara B14 HMR with a 24 inch 1 in 9 twist barrel
My load is,36.1 gn of RS52 with a COAL of 2.550
MV is 3500fps and if I do my part, accuracy like this at 100 yards is possible

Cheers

Bruce

One of the minds I was after.
Thanks Bruce

I can never figure this forum, ask for an opinion on a rifle calibre and you will get hundreds of replies with detailed reasoning for their particular recommendation. Ask for hints on a load recipe and you would think you were asking for the answer to life, the universe and everything (yes, I’m well aware the answer is 42).

Edit: Apart from Bruce, who answered whilst I was arguing with my wifi.

Some days you get golden answers and PMs with expert advice.

Other days your mother's morals get called into disrepute.

If you knew more about reloading you would work up loads to match your rifle, instead of following what works for another and could be dangerous in yours.

Consider:

H²0 capacity of your chosen brass

Primer used

Amount of throat/lead on your rifle and it's effect on seating depth

How the person giving a powder charge weight came up with the figure (digital/balance scale, do you trust yours will measure the same as theirs?)

But sure, you must know better...

It’ll be a custom barrel and chamber, cut however. The steel is this, the chamber dimensions are that, the length is different and the brass is too. The powder lot is whatever and even the projectile varies from lot to lot.

So ideas off a forum from someone with a completely different rifle / brass / powder lot and probably projectiles too is a farkin’ ideal way to start! Bugger the load data! Useless tripe! We all know it’s too conservative so lets go hot hot hot!

I'm not sure I like a plastic Australian getting sassy with me.

Hi Dave,

I load for 22-250 for myself and a friend.
I use Viht N150 behind the 69gr TMK with a CCI BR-2 primer, averaging 3362 fps with an SD of 7fps.
Not as fast as Bruce’s but shoots a gagged hole at 100 yards and @RoccoBMozo has achieved groups of 1.5” at 450 yards with this load.

Geeee maw , that yellow thing that rises every morning dun rose agen.

Thanks for your concern,I do what you mentioned when I reload already.
My attitude is I'll never know it all and always open to learn ,always.

So I don't understand your knowing better comment.

Can we stop jousting now.

Thanks sam

It amazes me how much effort some people go to when writing completely unhelpful replies!

There isn’t a great deal of reloading data for 22-250 and heavier bullets out there, so picking a powder can be tricky.
Choose what is easiest for you to obtain and go with that, N150 or N540 works well but N150 is a tad more temperature stable and tends to give very low SD’s.

I'd second Vhit powders presently given supply issues with others. It's one of the more reliable on availability. I would caution against using the same load data as others to begin with although if within safe limits of powder manufacturer's published data, can be a useful pointer providing barrel length/twist etc are the same as yours. If they're not, it becomes a crap shoot in the dark. You need to find a load for your rifle, with your brass, primers and powder which is first and foremost safe, and there are techniques and tools to help you find an good accuracy node

Other than Sierra, Nosler, Hornady, Vihtavuori, Alliant, Hodgdon… add more here… I suppose you’re right!

I used R/L 15 pushing out at 3350 ish if I remember correctly out of a 26” sassen 1-8”. Fed match primers and norma brass. Mind me on Tmoz and I will get the charge weight out of my book.
