    Well my rifle a.d.d. bug has bit me hard and i decieded i am going to try a barrel burning screaming banshee. I have both a trg 22 (308 bf) and 42 with magnum bolt face so i can do either easily. I am looking at wind cheaters obviously so i am open to other suggestions also.

    Mag lengths i have available

    trg 22 2.95 10rd mag
    trg 42 3.75 7rd mag

    as far as i can tell the basic ballistics are

    6mm crusader 115dtac 3200fps
    264 win mag 139 scenar 3200fps
    7 rem mag 180 berger 3100fps

    all of these would have between 26-28" barrel

    The other calibers i am seriously considering are 243 and 7/300 win mag. I am open to any ideas or experiences with any of these calibers.

    If you had one or two of these choices which would you make and why? The 42 doesn't currently have a barrel so it will get a magnum of some sort and the trg 22 currently is a 7mm08 (love it) just like to be able to play with different calibers and can't afford a third trg.

    7 Rem Mag or a 243 with Dtac's. The 264WM will defintely eat the barrel up under match conditions. Wore my first one out just trying to find a load for it. I was pushing things a little hard though....

    7mag will get 180's to 3050-3100 in a 27-28" barrel and will cheat the wind the most. A 243 with a Dtac at 3150 will come close to the 7RM, but less recoil, no muzzle brake, less barrel heat...etc.

    Just build both Scott!

    For a tactical match rifle or just shooting steel?

    On the 42 I say go for the 7/300WM.Thinking about doing one for my Surgeon XL next barrel for the fun of it.I've had a bunch of misses a hair off to the side of the steel at one of the local AZ matches and can't help thinking the extra wind advantage would of made my final scores different.The particular match I'm referring to does not have a velocity restriction.Currently the XL is in a 30-375R.I found out the hard way that with 240's going 2900 fps I couldn't recover the site picture fast enough on certain stages within the time limit.180's going 3150-3200 fps might be about right.Possibly being a good combination of fantastic ballistics and reasonable recoil impulse???

    Seems like all the tactical matches have a velocity restriction at 3100 fps so I didn't see any use going with the 6mm Crusader.Looks like 243 is the cartridge of choice these days.

    6mm Crusader at 3200 is steel safe at about 100 yards. Ask me how I know this

    Not the crusader. I believer the Danger zone for 115 dtacs is around 3350 and above.

    Re: 6mm crusader, 264 win mag or 7 rem mag???

    I didn't have any come apart at just over 3350, but they didn't shoot all that hot at all. Seems like 3200-3275 is a sweet zone and then the 2950-3150 range as well. I run them now at 3247 in one rifle and 3150 in another.

    I guess it wouldn't be the greatest idea to do the 7-300WM for a tactical match rifle because of the recoil and short barrel life but I ran the numbers at JBM out of curiosity and found out that with both the 115 and 180 going 3200fps the 180 has the 115 beat by 1/2 a mil at 1000Y in a 10 mph full value wind.That's pretty substantial!

    Re: 6mm crusader, 264 win mag or 7 rem mag???

    the magnum action would only be for a match or two a year and not any of the high speed, high round count matches. we just have a couple local matches where it would be fun. great for ukd's and cross canyon stuff.

    so what is this magic load for the 243 to get the 115s going 3150 so easily.

    Maybe, like me, he prefers moa/moa over mil/mil...?

    Knowing where the pressures are at for the 6mm Crusader with all of the powders listed above, I have a lot of trouble believing that there is any 243 load that will do that without the pressures going into the 65kpsi range.

    Have a look at MontanaMarine's primer test in his 30-06. Reading the brass and primers can be deceiving...

    Actually, about everyone that has had GAP build them a 243 (at least 6-8 people I can readily name) get that velocity with zero pressure signs. And that's with real world, rapid fire, hot weather comp conditions. I NEVER blew a primer in my 243 shooting that load. With multiple loads on the brass I might add.


    47.5gns RL-25
    Win brass
    210M primers
    115 DTACs

    6.5 mils to 1K

    Also, in a twist of irony I have had loads not even close to what MM loads in different calibers and it shows severe pressure and yet it's well below where he has seen pressure signs.

    what length barrel and what twist? coated bullets? reamer just for the 115's?

    Mike i believe you i just want to be able to replicate it. GAP builds one hell of a rifle but i struggle to go without my rifle for 2-3 months while waiting and I have an arrangement with benchmark barrels since they are local.

    Re: 6mm crusader, 264 win mag or 7 rem mag???

    You aren't going to blow primers at 65kpsi, that's within the SAAMI spec. for several cartridges (6mm Rem. for example). Primers are designed to withstand it. I have no doubt you can get that velocity, but it is a hot load.

    Re: 6mm crusader, 264 win mag or 7 rem mag???

    well guys after alot of debating, i went ahead and ordered my two barrels.

    same contour 1.150 for 4" then straight taper to .800" @ 28", 8 flutes with matching muzzle brakes threaded 5/8x24.

    1. 243 8twist 6 groove, throated for dtacs
    2. 7/300 wm 9 twist, 5r, throated for 180 berger vld's seated out to 3.60"

    I am shooting for velocity around 3100-3150 out of both and hopefully at least 1500rds out of each one. If for some reason i can't get it out of the 243 i will just order the crusader reamer and rechamber it.

    smokem if you gottem----barrels that is!!

    I got an LTR at a great price so rather than turn that one into a 243 (which still isn't out of the question) I thought the TRG should go that route, especially since it's my comp gun.

    Re: 6mm crusader, 264 win mag or 7 rem mag???

    scott, you'll love that 243, I have an AI and shoot the 115 berger cause the Dtac are always sold out where I look but, after shooting a 1000 yds match last weekend and watching the bullet trace in the rifle's scope, i have zero complaints, it shoots fast, bucks wind and is really flat to 1000 with barelly any recoil
    good choice brother.
