Range Report .243 And a Twenty Inch Barrel

[hillbillybear]

Just came into a nice semi-custom .243 with a 20 inch barrel and am curious if anyone has chronographed 95/100/105 grain bullets out of a tube that length.

If so, what sort of speeds were you getting?

I shoot at 22 inch with 105 Amax and it avgs 2925 with h4350

Tag. Thinking of building a shorty barreled 243 for the 87s

I only shoot 80-95g loads in my 22" bbl. 80s are at 3300 fps, 95g Nosler HBT is at 2947 w/h414 & 3015 w/blc2.
My pal has the 20" bbl but he only shoots 58/65g vmax as its strictly a coyote rig.

Taking a newly built .243 out in the morning before church. Winchester S.A., 20" Douglas SS air gauged, 1-0 twist. I loaded up 105 Hornady HPBT Match bullets with H4350 and some 90g Nobler BTs with same. I have not bought Lapua brass in years, but hear great things about its durability. Am wondering if annealing the brass will make the 100 pieces last the life of the barrel.

Just finished the 1st range trip with above rifle. Even though bullet seating depth was way too long and barrel was not broken in (lots of copper), managed .75moa to 200 yds with the 105s. Looking forward to improving groups with load development.
