Re: .50 peacemaker Vs .338 Lapua

FiftyDriver,

Please tell me what the Kahn is. I am intrigued by any 2000 yard rifle.

I wouldn't recommend the 50 as its case is too small for the heavy bullets at reasonable velocities and this is what seperates the 50bmg from the rest of the pack.The 6.5-284 is a ballistic twin to the 50bmg shooting military ball ammo in everything except energy.I would opt for the 300 or 338 RUM and a 34 inch barrel and use readily available dies and heavy bullets.The 50 peacekeeper is a novelty cartridge without much use.

Re: .50 peacemaker Vs .338 Lapua

Randy in PA,

IT is built off the 338-378 Wby case except that the shoulder is a conventional 35 degree shoulder that has been moved forward slightly to allow the firing of 338-378 factory brass for fireforming.

It has a slight capacity advantage over the parent case, about 5-8 grains which in a case this size is relatively slight.

I will initially be testing the 300 gr Sierra Mk but will also try some of Richard Graves 300 gr and 350 gr ULD rebated boattail bullets when they arrive and I get my rifle finished.

The 350 gr ULD's are said to have a B.C. crowding the .900 level. I expect to be able to drive these to at least 2900 fps and the 300 gr pills to 3200 fps or so out of the 34" Lilja barrel.

With these B.C. numbers and this velocity, it places this round at least even with the 50 BMG top end match loads as far as drop and drift are concerned and far better then any military style 50 BMG round.

With half the recoil to boot.

Only thing it lacks compared to the 50 BMG will be terminal performance but it will have enough for anything I need.

When driven to full level, these bullets should stay super-sonic to a bit past 2000 yards. We will see.

Good Shooting!!

Well, I decided to go with the 300RUM, its enough for my purposes and the action can be had easily. 240's behind a max charge will be ample to down boars at ranges past 600yds.

Thanks guys.

1. Recommend you reconsider your decision as it is based on the Sierra 240s which is no longer being made.

Not smart to build a gun for a bullet not being made and dwindling limited supply in field.

Several guys in PA were talking about trying to get up a 30,000 bullet order and see if Sierra would run them. Right now would not count on it.

2. Brass is the cheapest component of the system. Always buy the best brass that you can find IF you expect to use it LR or in competition. My last 338 Lapua brass cost $100 for 100. Quality is tops and have never seen any Rem come close. Now if time is nothing to you and you like sorting 200-300 pieces to get 50 then use Remington brass.

3. Time and money that goes into setting up a Rem action and bedding block, you can buy a 10" BAT action and hang any barrel on it you want. It will retain its value and it is made to handle the cartridge and pressures you want. The Rem is not designed for those pressures, even though some people stretch that limit and have not had anything happen to them yet.

338 Lapua Ack Improved will push 300 gr Sierra at 3100 fps with 34" barrel. No hog walking will stand up to that.

No one builds a repeating rifle for LR hunting with bullets seated into the lands and 30 lb stocks so that is not even an issue.

Re: .50 peacemaker Vs .338 Lapua

I dont know, but I think the .338 Kahn sounded much like the .338 Excalibur.
Am I wrong??

I just read your post about Sierra dropping the 240's.Are they planning a different bullet at a similar weight like the old 250 or just getting out completely? The reason i ask is i was going to have Mike Bryant set me up a fast twist barrel for my 300 Ackley heavy gun.
