22GT load data
- Thread starter Krob95

Anyone have any data for monos, specifically cutting edge 78gr mth or pva 77 cayugas?
I just ordered a 22gt barrel for coyote and ground squirrel hunting, but being in CA I have to use non lead bullets for hunting, even varmint hunting. Makes components rather expensive just to blow up a squirrel, lol
I need to run some numbers in quick load this weekend for powder ideas. I have plenty of varget and RL16 on hand, and I'm guessing either should work with the 77/78s.

I just ran some numbers in Quickload using a Cutting Edge 78 MTH with the driving band seated to right above the case neck, and RL16 looks like a winner for that combo. QL says 36gr is probably going to be way too hot though, I'll probably start around 33.5gr which it says should be around 51.5ksi because of the higher shot start pressure with the monos. 3300-3350fps looks attainable with pressures in the 55ksi range. Won't know for sure until the brass gets here and I can measure case capacity and also see how the barrel acts.
QL says RL26 should be the fastest power with the 77/78 monos, but QL currently doesn't have an option to "skip unobtainable powders" in their powder suggestion chart, LOL

I just looked it was 38.2 gr of rl16 with a 75 eldm at 3324fps out of a 20” barrel. No pressure spikes in 90 degree weather shooting Praire dogs. I’ve since switched the load to 40gr of n555 (very full case) and it’s pretty much the same velocity. Both loads shot great
Vit N555 should be right there with RL16, but will need +1-2gr.
These aren't necessarily top loads, just what I used on virgin Alpha brass on a new barrel. All below in first 100 rounds. It'll probably speed up 80-100.
The data below might help you to see how quick load is lining up.
New 24" 7T Rock barrel on Tika, virgin brass, & Fed 205 primer
90 SMK all loaded same length 2.522 / 1.993
6.5 Staball 38.0gr = 3047
RL16 36.1gr = 3022
H4350 36.1gr = 3052
Vit N555 37.7gr = 3097
My 22GT Alpha brass 1 x has 45.08 gr h2o filled to top.
Dry weight with spent primer = 145.38
Wet weight = 190.46
I still have some of those 78 MTH & might load a few for the GT.
Tried them in a Valkyrie & they shot like ass.
Good info, thanks.
I still have some cutting edge 78 mth as well from testing in my 2x 223AIs and a friend's 22BR... They also shot like crap for me in all 3. The Lehigh 72 CCs on the other hand were extremely accurate in both my 223AIs and the 22BR, but as of now the Lehigh 72s are not available.
I hope the 77 cayugas or 78 mth shoot good in the 22GT.

I appreciate the heads up. I ordered a few boxes. Although, I have to say that I've had fantastic results with the hornady brass.Alpha Munitions 22 GT SRP Brass (Box of 100) | 1776 Ammo

My brass arrived today. While I wait for my barrel and action I am thinking about reloading 100x so I can immediately shoot once it arrives.

I am thinking 34.0 H4350 should be a nice mild load. Thoughts?

34 will be mild indeed. I ran 35gr H4350 breakin load with 88eldm right around 2990-3000fps. Shot pretty well. Powder lot can swing that number +-30fps tho. 34gr with the short bearing but lighter weight will probably be in that same velocity area with a 26" barrel.
Wonder if that has anything to do with assuring the bullet makes it all the way to the target
I've ran 90 atips at 3270 from a 7tw 219 bore, and alls well at 400y on paper. That was early in barrel life. Over 600 now and never lost a bullet at 3100-3120, 90s or 88s.Wonder if that has anything to do with assuring the bullet makes it all the way to the target
Yeah I haven't lost any yet either. So far just fire formed and barrel brake in first 200 Alpha brass. 3100 with the 88's is the highest I've gone.
24" 7T
Reading through the 22 Creedmoor thread scared me a little with all the 88's coming apart in 7T above 3150.
36.1 H4350 with 90smk was looking pretty good @3050
Also going to play around with RL15.5 some more with the 88's 34.6-35.4gr

Just picked up a few k of those same bullets from them, quick shipping and as described.
Are they in fact 9290's if anyone knows?
I have 7.2 twist, fast enough to spin these up properly?

Sierra says 7tw needed at 223 velocity, I'm sure at 22gt velocity a 7.5 would suffice. They're factory pointed 90s. Can't expect them to be anything but the 9290s. @padom has been using them in a 22br from a 7tw and they've shot very well for him, more consistent than 88 eldm.
I have a PVA 7 twist coming and I’m a little afraid it may be troublesome. I’m hoping I can send them fast enough without them blowing apart and I don’t want to run solids. I wish PVA had more Osprey twist rates available.
I had zero issues with my pva obw 22GT 1-7 and blowing up bullets. Shot 88 ELD's lights out...
How fast were you sending the 88s? Had? Did you shoot out the barrel, if so how many rounds did you get out of it?
I have 88s and 85.5s. I may pick up some 90s as well. I was hoping to find 95s, but I think I have more bullets than barrel life at this point.

I didn't have great luck with 95's in 2 barrels...90smk, 88 ELD and 85.5's all shot great.
I just tested the PVA OBW for a few hundred rounds for accuracy while I was waiting on my Bartlein...it's still in the safe..
I do not have the latest update, but I use the 6x47 lapua profile and just adjust everything to match the GT specs. Case length, H2O and AOL, then just adjust the burn rate to match velocity. Works for me just fine.
