Some of you may remember early this year when I was going on and on about that Remington 788 I put together with a Boyd's stock and a Wilson barrel. My enthusiasm turned to disappointment when I was not able to achieve the kind of accuracy I had hoped for. Many folks here offered advice, some on the forum and some via private messaging.
I put the rifle away out of frustration in the early summer and spent my summer with a 700 in 223.
Lately I've been thinking of that 788 and what I might do with it. I was not happy with my decision to go with the .246” neck, given the extra work required prepping brass and considering the lack luster performance. I thought about reaming it for a no-turn neck, or even changing it to a 223. Maybe Ackley Improved.
But I thought I'd give it another try before making any changes. I remembered someone here told me crank up the velocity. So I looked up on Nosler's website the max load of H322, which I was loading for another rifle. I loaded 10 222's with the 40 grain tipped Varmageddon. Shooting at 200 yards that 788 gave me one .6 MOA group and one .5 MOA group. Hey now this is looking promising! ES and SD were quite large, though.
Yesterday I loaded a dozen more after figuring out how to solve a neck tension issue I was dealing with earlier in the year. Used 5 to sight in with and fired five for record. 100 yards this time. The result is the group pictured below. The first four made that perfect four-leafed clover that measures .199 inch (.19 MOA). I was like oh man, shot number five, the pressure's on
I just knew it was going to open up the group. Maybe I tried too hard. Or maybe I'll call it a “flier.” It was probably me...but there was a variable wind coming from about 10 o'clock so...anyway number five makes it a .35 MOA 5 shot group. I'll take that.
Average velocity 3,532. ES 32, SD 11
