great news today

[mr.big]

my gunsmith messaged me today that he had a 6mm Creedmoor reamer on order and should be ready for a bbl in a few weeks,,my 243 barrels will need replacing by then and I cant wait to try the 6 Creedmoor,,I think it will be a more accurate design and hopefully barrels will last longer and I wont lose maybe 75-100 fps,,

the 243 is hard to beat ballistically but keeping the brass in shape is a job and bbl life for match type accuracy is pretty short,,but for banging steel the 243 is a heck pf a round,,I will give up a little velocity for longer match accuracy bbl life,,

first bbl is gonna be a Brux 7.5 twist HV .236 bore finished at 30 inches,,should run the 107-110 match bullets in the 3175 =3200 fps range and shoot very small,,

I cant wait,, :super:

not that you can shoot much smaller groups, based on your great shooting skills already but you should see some accuracy improvement.

It would be a toss up for me between 6 creedmoor and 6x47 Lapua. Can't go wrong either way!

hey mr. big how many rounds to you consider " pretty short" for match grade accuracy in the 243. Just wondering.

 

[mr.big]

1000 for match grade accuracy which I consider 2 .25 inch 5 shot groups at 600 yards ,,but I am still hitting 10 inch steel plate at 1025 at about 3,000 rounds,,

which makes for pretty good use from a bbl,,put a 1,000 rounds on it on the bench rifle and then have it set back and rechambered for my prone rifle,,

pushing a 6mm 105 gr bullet at 3200+ fps is gonna be hard on bbls no matter the case it comes out of,,
