Nothing major but I figured someone might be interested.
Went out this morning and shot R17 through two 300 WSM's.
Looks like a solid 50fps gain in velocity compared to H4350.
Both rifles topped out at 3000fps shooting 180 PT's and AB's. 64.5 grains for the A7. 65 grains for the 85. W/W brass/CCI250.
Shooting in a brisk wind at 400 yards, accuracy averaged about 1.5MOA for the Sako A7 but was simply phenomenal in the Sako 85. Very low ES and the rifle went .5MOA for one group and 1MOA for the other. Vertical spread for 7 shots was about 1.5-2". I couldn't believe it as I've been trying to get AB's to shoot in that rifle off and on for over a year.
Look out yotes!

Thanks for the update - I've used R-17 in my 7wsm but will be trying it in a 300 wsm after Christmas.

Alliants load data is too warm for my rifles(they list a max of 66grs for 180's).
It looks like a guy can safely sub H4350 data without any worries(R17 appears to run about a grain 'slower'). Good luck and let us know it goes.

Yeah, maybe a little.
You should do a 17WSSM.

Question for the gurus.
I wonder if any noticable decrease in barrel life will occur using this powder? A 50-100fps gain can't be that harmful(or can it?).

Sam,
Why the worry about barrel life with rl 17? Is it harder on barrels than other powders?

I'm not really worried just wondering given it is a set-up speed wise. I guess there is a different pressure curve so who knows....This crap and the Beam boggle my mind....(grin)
Somebody claimed that certain 'quick' VV powders were hard on throats.
No doubt R17 will be just fine.

I doubt that speed will make much difference in barrel life. I had the exact same experience as you. My 7.82 patriot picked up 50-75 fps over H4350 and was more accurate as well. I shot one animal with a 150 TTSX at 3350 out of mine and it was a DRT Muley buck. Pics in the deer forum.

I've been reading the various post on the powder and finally tried some as my H4350 stash(for Bob) is down to a few pounds and it's hard to find locally.
It didn't do much in the one rifle accuracy wise but flat amazed me in the other.

My 300 Saum picked up over 150 fps over any of the 4350 powders, hunter and H414 with no visible pressure signs. But the best accuracy was at 1.5 grains under Alliants listed max with a gain of 85 fps over the other powders.

150 fps is a major gain.
I think Brad and some other guys have got about 100fps more.
50fps is about it for me but accuracy appears to be there.
I plan on trying some 200 grain AB's with R17 and the A7. That combo shot like crap in the 85 but who knows.
And Dober, 'nice' day at the range. Had the place to myself, imagine that....(grin)

My 7MM Saum did not get not get the velocity increase that the 300 did but with the 160 grain nosler pt I was able to use 10 grains less powder than my previous load of 66 grains oh H1000 to get the same velocity with less muzzle blast and accuracy was about the same.
