If you want it to group at 2 miles, it first has to group at 1 mile. As far as cheytac based cases are concerned, are they even capable of1/4 moa at any range?

The Cheytac parent case is more then capable of 1/4 moa. I use this case in my 338 and 375 AM and both have shot a load of 1/4 moa groups. This is my personal best three shot group at 1800 yards fired with one of my XHS repeaters in 375 Allen Magnum.



The three shot cluster measured just a hair under 4" ctc so well under 1/4 moa. The impact at the bottom of the gong was made from 4 hours earlier when I was trying to hit the gong in severe mirage and out of 5 shots, that's the only one that hit. Later in the evening, clouds came over, cooled off for no mirage and no wind, perfect shooting conditions and it showed with a great group as a result.

The Cheytac case is very capable of fine accuracy.

I would agree that I have a preference for lead core bullets for best accuracy over a wide range of different rifles. Solids can be very finicky depending on bore diameter but if the match is right, they can be amazing. Still, the lead core bullets ARE more forgiving over all.

Glad to hear the gun is almost complete. Some great mornings to shoot this time of year.

Re: 3650 yards target nailed !!!

Hmmm Maybe we need cut the BS. Then get a group of the good ole boys together kind a shoot off at 3500 yards. So find a place to set it up , make a video pound a bunch of bullets at 8 foot by 8 foot chunk of steel. or 6x6 piece

Sort of a come one come all shoot. Take the gloves off ! !

Also this would put aside any doubts about what works. Test some good equipment

Would make for a good thread to read.

Kirby has been at this for may a year. My money is on the guy who has spent a life long dream on making guns for long range. What ever that is to some.


Great read so far.

God Bless everyone.

Jeff

Love to shoot flatter, faster and above all farther

Thanks, that answers that. My only limited experience around one of those things was not nearly as impressive. Of course we made him, as the rules dictate, shoot 10.... wasn't pretty lol.

Yes, about 2650 with the Terminator +P. But we have shot the Bergers in many slower 338's and found good results even after the sonic transition. Most of this testing was above 3500 feet.

Re: 3650 yards target nailed !!!

Here are som pics form when I tested 300 grs Bergers at 2200 yards at sea level.
MV was 2736 fps out of my 338LM. It was a very mild load, but it held tight groups at 1000 yards.

The 5 shot group measures 40 inches, including the coldbore shot.
The bullet has no problems going through the transonic range and into subsonic speed. It was a bit windy, and I struggled with the terrain where I was shooting from, it was a wet spot, and I sunk deeper down into it for every shot I made.

Will try again when my new barrel in 338LM Imp is ready.

Load development starts this morning, will keep you posted. Looking to drive the 300 gr Berger to 3350-3400 fps in your 32" barrel length with good brass life. Do not think that will be a problem. Will keep you posted with results.

Also going to go out tonight and look for some 3K places to shoot. I think I have a couple possible places to go but have to check them out first. May be running cattle on them right now.
