Does anyone have any pet loads for this? Hoping to use h4350 and bullets in the 80 gr range. Could likely start with 22 250 data but getting some already tried loads would be good.
Thanks
 
38 gr of H4350 under an 88gr ELD-M in Winchester 22-250 brass (fireforming load with max pressure for a CCI 200 primer). It ran just over 3200 fps in a 25" barrel. At 2.70" COL it's just off the lands in my chamber. I haven't gotten around to loading the fireformed brass or neck-turning my 6mm Creedmoor brass.
 
I have worked up a lot of loads for a couple 22cm rifles. Here's a few of the loads that have worked best for me

Reduced loads :
Hornady 50gr SP, 15.3grs Trail Boss ~ 2300 fps
Barnes 50gr Varminator HP, 32.5grs H4895 ~ 3300 fps
Nosler 55gr Varmageddon Tipped, 42.3grs H4350 ~ 3610 fps

69gr Sierra Tipped Matchking, 42.3grs H4350 ~ 3560 fps

70gr Nosler Accubond, 41.5grs RL23 ~ 3530 fps

75gr Hornady Amax, 45.0grs RL26 ~ 3400 fps

75gr Swift Scirocco, 43.9grs H4831sc ~ 3420 fps

77gr Barnes LRX, 36.6grs RL16 ~ 3200 fps
77gr Barnes LRX, 43.4grs RL26 ~ 3440 fps

77gr Sierra Tipped Matchking, 42.7grs RL23 ~ 3450 fps

80gr Hornady Amax, 38.0grs RL16 ~ 3240 fps

80.5grs Berger, 43.2grs RL22 ~ 3200 fps

88gr Hornady ELD, 39.5grs RL22 ~ 3190 fps
88gr Hornady ELD, 43.6grs Retumbo ~ 3200 fps
 
I've also used 50gr Speer bullets #1029. I shoot them at about 223 speeds with the following fireforming load.

Winchester 22-250 brass, CCI 200 primer, 2.40" COL, light crimp with Lee factory crimp die, 27.5gr IMR 4198 (actually Canada Ammo's D4198 non-canister grade). The velocities are about 3350 fps and a 0.836" 5-shot group at 100y. Pressure is low and the shoulder isn't fully formed - it's a bit round.

I also shot the 62gr Gold Dot at 3640 fps with 37gr of H4895 but they sprayed over a 2" group. I have a 1:7 twist so the rpm would be pretty fast!

The loads you have listed are they near max pressure in your gun. See you use a lot of reloader powders. Thanks everyone for the information
 
Rifle build specs in 22cm
-ks arms 3 lug action
-ks arms 22" 1:8 twist
-ag composite chalk branch stalk

I've got really constant results with
-seirra 69gr smk
-2.160" col using a comparator
-41 grains of h4350
-sitting .020" off lands
-cci small rifle primers
-alpha munitions brass ***once fired
-running 3500fps using magneto speed chrono
-shooting off a bag and bipod i am getting 1/2 moa groups. Depending how i shoot that day it will spread to 3/4.
-***note with this, I did a ladder test, started at 41gr and went up to 43.5gr h4350, best group was 41gr and opened up as i used more powder charge. I want to revisit this load. With more powder.

I use this gun for coyotes, the 69gr does great things to dogs with minimal damage. Drops them in their tracks
and i have never had to shoot a dog twice.

I made some loads with 80.5gr berger fullbores
they grouped really well but i was popping primers. So they were a tad hot and ran 3500fps aswell with 43gr h4350. I don't reccomend using this load
-alpha brass
-cci primers

Hornady 75gr eldm
-43gr h4350
-cci srp
-alpha brass
-2.115" col using comparator
-sitting .020" off lands
-3480 fps
-alpha brass
-grouped 1/2 moa, was a good group but scrapped the idea of eldm's as i want to keep fur and have had carnage with eldm's on fur in the past


I want to revisit a bunch of my loads i have with other projectiles now that my barrel has spead up after break in. Maybe thinking the accuracy node with powder weights will be better.
