Home Forums Hunting & Shooting Hunting Rifles DIY bedding M77 (pic heavy)

I shot my bet groups to date with this rifle today.

Not bad for a first attempt at handloading.

My 60 gr of IMR 7828 under the 130 gr TSX was typical for what I'd seen from factory loads thus far accuracy wise.

When I jumped up to 62.5 gr of powder things started to tighten up.



3/4"

Then the 65 gr of IMR 7828, 3/4" group here too. This was after a scope adjustment to bring things down as the point of impact climbed with powder increases.



Accuracy wise the 62.5 and 65 gr seemed well matched.

But I was worried about the 65 gr being a little too hot. I had one piece of brass (mu first 65 gr load) stick a little on me, hard to extract.

I put a light film of oil on the rest of my 65 gr loads and they extracted effortless.

But I'm still thinking I'll back down to 64 gr and give it another go.
