So I have shot my 50 cal over the last 2 weekends with mr hollow point 300 grains and Neilsen 235 grains and accuracy his awful to say the least. Can’t even hit the 8” target at 50 yards I have the atn 4K pro attached with the one shot zero that works great with my other guns. I shoot off a bench and using a bipod. Just curious if anyone with the 50 cal go max has issues? The crown looks fine and I used a q tip around the crown there were no snags I also cleaned the barrel. It possibly could be me I will try to shoot off a bag instead of the bipod there is some kick to her.
From my research and talking to mr hollow point 498 is the max size to use. I’m gonna try shooting from a bag after watching my videos from the atn it looks to be kicking sideways I’m gonna try bags this or something different this weekend if I can get out.
I would try a conventional scope before giving up on it , I have the 4K pro on my .25 gauntlet and it gave my fits before I got it zeroed, just a thought, I would also slug the barrel to verify the bore size, my 45 challenger was .461 not 457 ,so it pays to check actual bore size.
I fill to 4500 I chornographed the Neilsen 235 grains, first shot was 759 and the last shot #( 603 and is identical to groups of the 300 grain mr hollow point. Unfortunately I did not chrony the 300’s but I suspect mid 600’s.
I shot my .45 AEA at lunch today. Fill to 3200 for 5 shots with my cast 350 gn slugs. 756, 793, 812, 796 and 754 fps. 3000 psi is the sweet spot on this rifle for 3 shots. Depending on what you want your rifle to do, you shouldn’t have a problem launching 300s with it. The trigger is the worst problem with my AEA. I forget about trying to do a nice smooth trigger pull with it. I shoot it like my carry gun. When I am happy with my hold, I pull the trigger. Might not be the correct way to shoot a rifle, but it takes a lot of the wiggle out of waiting for it to go off. By the way, 4 of the 5 are touching at 50 yards.
Well I went out today with bags and the atn 4K. The bags were better but she kicks a lot I used the 300 gr mr hollow points again 4500 fill. First shot was 707 on the chrony and the fifth was 601. Trying to upload a picture of target but it’s to big of a file. Any ways still aloo ver the place but I had two shots touching out of 5. 60 yards was the target.
So when I shot her this weekend the first shot was way off bullseye so I re sighted her in and the next shot was 4” low but under bulls eye shots 3 and 4 were touching each other (top and bottom touch) but 4” to the left of bullseye and shot 5 was using hold over to get close to bullseye.
