20-250 with 41gr Hammer HHT's???

I am considering building a 20" 20-250, looking to build about as flat and low recoiling gun as possible to 400 yards. I was wondering if anybody out there has messed with the 41gr Hammer HHT's in a fast .204 caliber. I ran the ballistics based on their .134 g7 bc at 4100 fps and no other combo I have came up with is even close. My guess is these will hold together and not create some of the splashing issues seen with most bullets in this weight class at 4000 fps plus. Would love to hear any feedback. Hoping to make a decision before all the black Friday sales start up. Thanks!
 
I've never messed with the Hammer bullets, so can't say anything about terminal performance. I think getting 4,100 fps from a 20", 9 twist barrel is probably going to be kind of spicy though.

Copy that! I was guessing based on other 40's load data I came across. 4000 possible then? I have read your write up several times and appreciate the available info.

I would also be interested in hearing if anybody has tried the 50gr black hole with the rebated boat tail.
 
I've been reloading for right around 60 years and things keep getting wilder and people seem to to have a lot of disposable cash burning a hole in their pockets.

I read this and can't see anything accomplished that a standard slow.twist.22-250 with 40gr NBTs won't do vs spending literally thousands of dollars to.build.a.wierd.wildcat.

Good luck on your project.

Hard to say. I'd guess "probably". But I've never worked with solids, and there are so many variables, hard to say. One of those things you won't really know until you try. I'm getting 4,100 with 38 gr. cup and core out of a 19", 12 twist. So, in the ball park.

But I'd be surprised if there isn't someone who has tried them. Especially after the 50 or 55 cup and cores started going "poof".

Got a wildcat 20mm GT AI running the 41HHT at 4200 FPS. I am hunting coyotes and hogs with it this winter. I’ve already run the 41gr tipped and non-tipped versions through coons. All DRT, I would leave the tip in. Also shot the 40gr V-Max around 3350 FPS. Definitely explosive on critters. I pushed the 40gr VMax to disintegrating velocities around 3800FPS with my fast twist 1-7TR.
