Anyone have any experience on deer sized game with a .243 cal hammer bullet? Setting up a first deer rifle(243win) for BIL and thinking I should make it a hammer to maximize trauma and penetration.

Anyway, I don't see him taking a shot over 250 for a few years so I'm gravitating to the sledgehammer line. Rifle is a weatherby vanguard and from all research must have a 1-10 twist. Only sledge that lists being able to spin with a 10 twist is the 71 grain.

Any experience with that bullet or any other 6mm hammer on game on here? (long shot in LRH I know)... I'm thinking I can get that up to 3200 or so without leaning on it.

thanks for any help

Ask Steve, I'm sure he has some powder/bullet combos. You ~might be able to get away with the heavier 88 sledge depending on speed and altitude. I have pushed bullets in the 100 grain+ class near 3,400 fps with Reloader 26 so you should be at least 3,300 with 80 grain pills.

I will likely call him tomorrow, just didn't know if anyone had used them.

I have a feeling the 88 will be accurate I just know Steve prefers a high stability factor

I am at about 3 hundred feet elevation

I took a mule deer this year with the 102 gr Hammer Hunter in .243 caliber (6 Creedmoor). I realize that doesn't help you much re. the 71 or 88 gr Sledge Hammers, though I would have no qualms using those bullets. My shot was less than 100 and did everything expected.

I imagine you will easily surpass 3,200 fps with the 71 gr Sledge Hammer in 243 Win. Likely easily surpass 3,400. You'd probably be in the 3,200 fps range shooting the 88 gr Sledge Hammer.

By my estimate, you'd need to be at about 3,500' elevation to get a stability factor of 1.5 with the 88 gr Sledge Hammer from a 243 Win.

In a .243 Win? With the 71gr., you should be WAY over 3200.
I run a 101 Hammer Hunter in my 6CM, and get 3180fps.

Cool! I am not chasing speed, only chasing an accurate hunting load that will perform on game

Added points if I can do it with H4895 since I use that already
 
We tend to split hairs-I'd run with the 73 grain and not stress. Within the parameters you mention it will be fine.

The 6mm I've used over the years, has mostly been 100 grains. Stepping down to 73 seems like a whole bunch. It's really a different style bullet though, and a change in thinking is needed.

I've never shot coppers before so I agree on the weird feeling. You're also right on the splitting hairs, I should just buy some and shoot stuff lol
 
While I can't run it in this rifle I'd love and welcome any info about 6mm hammers. Let's hear it!
