Just picked up a Rem 742 in 308 for S&G's. Always wanted to play with one.
First day was with some Win factory 150gr SP. Went bang but groups at 100yds showed a nice pattern of around 2 to 3" for 3 shots. About what I expected. Lots of vertical stringing.
At the loading bench, I decided to treat it like the M305's but FL sizing was necessary to chamber properly.
Started with 41gr of Benchmark in Win brass lit by a CCI BR2 primer pushing a 155gr Amax and went up in 1/2 gr increments to 42.5g. Not expecting much but at least would get an idea how to proceed.
Today was very calm, warm and a bit muggy. Was able to set up at the 200yd backstop.
Three rds later, I had a nice 1" triangle
This while shooting with a 4.5X scope. The reticle covers about 1", maybe more at 200yds.
That's weird but in a very nice way. Tried the 41.5gr. First shot was on a target that fell off the backstop - oops. Next two on another target were again 1 1/4" apart. Hey, now we are on to something.
Going to 42gr showed immediate vertical stringing (still a very respectable 3" group) and 42.5gr, well let's just say it went bang three times.
I have always known semis to be fussy and many don't like running hard. However, I am really surprised at how well this rifle can shoot. 1" at 200yds. That is certainly worth trying again and with a target scope.
Hodgdon max is 43gr with a 150gr bullet so this is right up there in pressures. Brass is just a bit sooty around the shoulder. I bet I am running 7.62NATO pressures.
Will certainly retest but for all the Rem semis out there, it might just be worth working up some moderate pressures loads with match bullets to see what your rifle can do.
Gotta like it...
