anybody had experience with this little guy in a contender or anything over a 20 in barrel

 

[ROBSTER]

No , but the case capacity is about the same as the 22 hornet.

cool i'm in the process of having tc custom shop build one for me so I have another plinker. i already have a 22 k hornet and my daughter has taken that over and was just wanting to try something different

 

[ROBSTER]

Had the same idea I have a 22 hornet also and was thinking about the 5.7 x28 also

It will be interesting how the little bugger turns out. Now the waiting game begins 10 -12 week wait for that barrel. i guess the first week of june isn't to bad.

price of ammo is def. a little cheaper over a 22hornet and also with better factory loaded bullets. the v-max round would make a heck of a critter ridder. i was thinking about getting a 5.7x28 upper for my ar...but i jst can't really justify it since the .223 is cheaper for me to shoot since i reload. also since i'm varmint hunt alot the .223 also has a little more punch. 5.7x28 would def. be good plinker tho.

i just picked up a hornady reloading die set and 500 rds of brass from topbrass so i plan on reloading this caliber. Might be a waste, hopefully i can push the shoulders back enough after they have been fired in an automatic it kind of rounds the shoulders off. I guess they reload them for the autos so maybe it won't be that bad. Also picked up a primer pocket swager to take care of the primer pocket issue.

I have the ar57 upper and it does a number on pdogs from 30 to 150 yds. I found it is almost as quiet as the 17HMR but way more lethal.

I been think of doing the same. What sight's are you using?

 

[glbpmc]

Leupold 3-9x40 with warne ar rings, and with this set up you can load the clip without removing the scope. Also I cut the top 1/4 " off a 30 round clip and removed the spring and it has worked great for a brass catcher.

Thanks, so a 40mm obj and 1" high rings enables the mag to be changed. Thats what I needed to know. I better get kickin on an a 57 upper.

The warne AR rings are for specific use on an ar platform and appear to be slightly taller than tall rings.

The load data I found is not adequate so I will play with some other powders and keep looking.
Anyone found a honestly good load for the AR57 and 35 or 40 grain bullet?

I know this is an old post but i have finaly had a chance to play with my ar57 upper. i have found for mine that 5.8 grains of true blue, cci 400, berger 40 molly, seated to a oal of 1.530 seems to be the best for me so far. crono today was 2218. i need to shoot this at 100 since i only did 50 yards today shot four five shot 1/4" groups with this load. defentaly a touchy round to load for. I only wish i could get the 40 Vmax or SBK to shoot as well as or close to the Bergers but so far the best average I have got from them was in the low 4s at 50.
