Home Forums Reloading Varmint Rifles 22-250; 75 grain Amax

Any of you guys have experience with this combo? I am trying to find a good load for the 75s. I shot 36 and 36.6 grains of H414 today but they ES was significantly higher than I am used.

I've been playing with the 75 gr HPBT in my 22/250. I tried 760 as I had a decent amount of it with no use so gave it a try. I was disappointed with the accuracy.

Next up was Hodgdon 4064 and Varget. Both of those gave me good starting accuracy. I am working with the Varget as I have plenty at the moment. I would like to find a companion load using IMR 4166 to use on occasion to clean the copper out.

37.5 gr RL 17, WW Brass, CCI 200 75 Gr AMax, 3244 FPS 5 shots, .437", 1in8 Tikka 22-250

Dennis send me your E mail via text or PM and Ill send you my Excell File 22-250 load data Kurt

Dennis,

I've used H 414 in the 22.250 with a fast twist and the 75 A Max, 80 gr A Max and 75 BTHP...

yet even tho the velocity spread was the highest of any load tested, the most accurate load used H 414, from 100 yds out to 400 yds.
with ANY of the three bullets...

I tripped over at a later point tho... the fastest velocity and accuracy combination with those bullets turned out to be 33.5 grains of 4064, which gave an MV of 3350 fps out of a 24 inch barrel from Pac Nor, 1 in 7 twist, Stainless barrel.

Don't know if you remember when we had the Campfire Get Together in Texas at Ed Too Many Letters place, we had a long distance shoot. you won that one, until they found one target that I hadn't put my name on.. my group was the smallest. I was shooting that 22.250 with the 1 in 7 Twist Pac Nor barrel on a Ruger 77 Mk 2 action, and my load was the one above... 33.5 grains of IMR 4064 with a 75 grain BTHP....

So that should attest to its accuracy potential.

I'll look and see if i have any 4064. I have mostly slower powders

Great accuracy with 75 A-max and H4350 in my '250

Same here. Great combo all the way around.

What kind of velocity y’all getting with H4350?

3025, but I'm shooting from an 18" Barrett Fieldcraft.

I was just reading about this in another thread and posted about filling the case full of 4350 and knocking the excess off the top and running a 75 Hornady on top of. Shot great. Lots of dead fur too. I think you can get like 41 or so grains in that case. Should run around 3000.

my post in November, once again... doing a lot of testing the fastest MV achieved and with darn good accuracy to boot...

33.5 grains of 4064....3350 fps with 75 and 80 grain bullets, out of a 24 inch Pac Nor Stainless barrel, in a heavy magnum contour, with a 1 in 7 twist...

and at the time, I thought I'd find that with H 4350 or IMR 4350.. but I didn't...

4064 and followed by RL 15 for the velocity and accuracy champs.. IMR 4895 NOT that far behind either of those powders...

Yea, 4350 won't get you there velocity wise. 4064 and varget will do it. Wish they wouldn't have stopped making 4320. It's a good powder. H380 ain't bad either. Buddy locked his bolt up and welded a case head to his boltface one summer. Load was good in the winter. One 90 degree day he shot a few shells that had stiff bolt lifts then boom, locked her down. Stuff is hot.

Lots of good options here.

Varget is the preferred powder in my two faster twist 22-250s.

My 22-250 had a 24” 1:8 twist Criterion barrel. With 75gr Amaxes, I got tiny groups and decent velocity (3167 IIRC) from R15. 5 shot groups at 700 yards were 3-4”. I tried H4350 but never got near the precision that R15 gave me.

Currently shooting 88gr ELDs from a 7” twist .22GT. Pretty much identical case capacity to the 22-250. This combo likes H4350, giving me a 10 shot group in the .4s.

So, I’d recommend something in the R15 burn rate with 75s and something in the H4350 burn rate with 88s.

So at what point as for bullet weight is it best to jump ship and move on to a 6 mm?

why limit yourself?

I shoot a lot of 22 cal and 6mm both...

waiting on my first 6 x 45 barrel...that an a 6 ARC is next....

I admit, I spend more time at the rifle range, testing stuff...
and second most activity is shooting a zillion sage rats each spring and summer

I shoot 6 to 8,000 rounds a year down range in some activity....most being 22 and 6mm... but last few years added 17 Fireball to that list...

In Oregon, I can shoot one deer a year... and I don't go elk hunting, because I've been shot at too many times by other elk hunters, that will shoot at any noise they hear...and have been fairly close to where other elk hunters were shot and killed by a fellow elk hunter, once they were two guys in the same party of like 10 in number...

I have a Savage with the 1-9 twist. I could never get the 75s to group good enough to make up for the accuracy of the 69 smk bullet. They shoot around and inch at 100 but the Sierra is better. Edk

I just bought a Ruger American Predator in 22-250. It's my understanding it has a 1/10 twist. I bought some RCBS dies from a friend and he threw in a pound of RL15. I will be loading some 63 grain Sierra SMP's. Does anyone have a pet load with a similar weight bullet and RL15 ??

63 grainer, ( Sierra SMP)... 23 to 26.5 of Reloader 15...this is for the 223.

I can tell ya from experience in my bolt action 223s, if you want the max punch with that bullet, there is no problem upping the charge up to 28 grains in my rifles...brass or rifle never noticed the difference...

If it is NOT hot weather or high temps...take a look at the charge for W 748 down below that...I've used that for both the Sierra 63 SMP and the Speer SMP 70 grain...give the candidate a real hard punch....

for the 22.250:

https://stevespages.com/224_7_63.html

also look at W 748 here also... both bullets will stabilize in a one in 14 twist, so 1 in 12 or 1 in 10 will present NO problems stabilizing... with any powder..
