Home Forums Lever Action Central Lever Actions - General .360 Buckhammer

I didn't take a picture of the group I shot with ammo using the Federal magnum primers. It was embarrassing. I believe the slower speeds and poorer accuracy is due to too low of a powder charge being used in fireformed brass. I'll load a ladder and work my way up shooting them over a chrono.

I used Fed 215 LR magnum primers with these loads today. I'm going back to LR standard primers. Although my SD was only 13 for the one load I chrono'd today, accuracy was abysmal.









These bullets were chrono'd at 2372fps. They were used soley for fireforming as I didn't expect them to be very accurate in this barrel.

I would think these would be the ticket in the Buckhammer.

My thoughts exactly. They kill well in the 357 Maximum too.

You are probably a pioneer of sorts with your work on the loading of the 360. That's some good velocity for the amount of powder. That's in the 358 Win camp right ?

Slower than 358 Win but maybe a little bit faster than most 35 Rem loads. Sorta depends on the 35 Rem barrel length and load.

I loaded another ladder last night using the Speer 180gr SPFN, A1680, and WLR primers. With a little luck I'll be able to test them later today. I will also try to fire one of those Speers into a box filled with water-soaked papers and magazines. Wish me luck in getting a kitchen pass from the defacto head of household.

Sometimes you have to wonder if the ammo/firearms industry is involved with state game/wildlife commissions. This would be useful to them in the state creating absurd regulations so as they can boost new products for forced state compliance to utilize new inferior chambers/cartridges. All in all, these new chambers are much less desirable than ones used over the last 120 years. Just a thought. What’s the threat range and critical ballistic differences in utilizing the 30-30 Win or 35 Rem in lieu of these new chambers? I’ll tell you, not a damn thing.

PGC has a magazine type rule book you get with your license, they sell ads in it.
For 30 years we had a muzzle loader season after Christmas, flintlock only.
The only such season.

Around 2003 there were ads in the book for in-lines.
Odd, considering they weren't legal for anything but rifle season.
The next year we got a one week, does only, any muzzle loader season.

Our archery rules never allowed crossbows.
When I saw crossbow ads in the rule book....😉😉😉🤣🤣🤣🤣🤣🤣🤣🤣🤣
If you ever want to bow hunt PA, crossbows are legal!

Speeds:
38gr: 2369fps (two recovered bullets were fired at this speed)

37gr: 2302fps

36gr 2222fps

Have you tried anything else besides 1680 yet,
I just got a tracking # from MGM for my Encore barrel so hopefully will be doing some load testing in the next week or two.

There's two Henry 360 X models on gunbroker, maybe the blued & Walnut version will show up soon at some gun shops

No other powders tested yet. I wish I had some data or more experience with Rl7. I think it would work well.

RL7 might be a good one. I've been using 748 Win. and has worked well for a few cartridges. Using it for 35 Remington for awhile with success. Getting over 2200 fps out of 20" barrel pushing 212 gr. RCBS FNGC's.

I reconfigured data in QL using 35/30-30 Win as a base reference. 1.8" case length, 2.360" COAL, 41gr of H2O, etc.

A5744 shows more promise than any other powder I looked at.

QL says my 38gr loads of A1680 are over 114Kpsi so I don't exactly trust that my data is correct or QL is computing it correctly.

I have a 360 buckhammer G2 contender 18” barrel from SSK. I stated to load this cartridge with way slow burning powders. H4895 was first and then benchmark velocity was too low with a full case of powder with these two. Next was H4198 and looked like a good fit but wanted to get a little more velocity so tried H4227 which gave more velocity but started to have high pressure signs.

Went back to H4198 using the Speer 180 grain bullet seated to the cannelure got a little over 2100FPS using 30 grains of powder in formed PPU 30-30 brass. Fired case looks fine no real pressure signs at all. I feel this load is safe in my barrel I worked up this load starting at 26 grains, so if you want to try it for yourself start there and work up for your rifle.

For now this gets me close enough, and will wait for load data from Hodgdon. I am interested in which powders Hodgdon specs for this cartridge.

I wanted to add this about forming 30-30 brass. I am using RCBS dies and replaced the decapping rod with a .338 decapping rod with expander to do the first pass neck up. I rough trim the brass first to 1.810” then do the first pass with the sizing die, next I use the .358” expander die then resize again to get everything in spec then trim to 1.800”. Run the .358” expander again, brass is now ready to prime and load.

I used to load the 180gr Speer FN in my 356 win & increased pressure loads in my 35 Rem .. what game I shot .. I never recovered a bullet .. but expansion was diffidently noticed … .. its a good bullet .. stout bullet

It’s my understanding that 30-30 brass isn’t built for the pressures some of the cartridges such as the 375 Win and the 360 B. will generate. In my 375 Win, I only use reformed 30-30 brass for cast loads.

For the sake of conversation, wouldn't it be easier to form cases by starting with 38-55 brass?

Yes if you have them or .375 winchester I've formed 360 BH from both but I have a good supply of each and 30-30 brass is much easier to find
