The best way to ruin a hard hitting kill every rifle that has been doing the job for decades is to chronograph it.

Or punch paper with it.

Sierra 150 grain spritzer and 80 grains IMR7977


Nosler ballistic tip 180 grain and 74 grains H4831

Weighing 12 of the Winchester cases came up with:

233.8
235.6
235.7
235.8
235.9
236.3
237.5

242.1

Speer 200 grain spitzer and 72 grains R23 in the Win cases that weighed 237.5 and up.


Speer 200 grain spitzer and 73 grains R23 in Win cases that weighed 235.6-236.3

try some RL 22 or 19...

I have been trying Reloder 23. Its only $22 a can here compared to $28 for R22.

This is the Holy Grail 74 grains of H4831 with a Sierra 180 flat base that was recommended earlier. The second target was definitely good. 4 shots each.

I see a clear winner here though with R23 and the 180 Sierra, also 4 shots each.

This is two shots of 250 Barnes originals and 71 grains Retumbo. Only about 5/8" apart.

Ive always used 75 to 76 grs. of RL-22 for velocity and accuracy in my 300 Winchesters with the 180 gr. bullets. its a tad below max in some books.

With 200 gr. bullets, Accubonds and partitions, I used 74 grs. and that was max in some guns, others would shoot best with 75. Work up this load with caution. it can be warm in some guns.

I used WW brass and Fed. 215s.....

Before & After photos.

Rifle: Win post 64. 300 Win Mag. Pac Nor barrel. Barrel bedded tight for first 2 inches (chamber area), action bedded tight. Remainder of barrel free floated.

Three shot groups were horrible:



After a little investigation I found the front action screw was too long by about 0.004" and was contacting the right bolt lug when the bolt was in battery. Prussian blue tells the tale.

Ground about 1/32" off the screw and headed to the range. Shot at 100 yards.




The load:




A week later, 180 grain Nosler Ballistic Tip, RL22, 75.0 grains, CCI250. Hmmm. Looks like Ray's load!

Shot at 200 yards:



There was not a chronograph in sight!

I still don't understand the chronograph remarks. I just like to know when to back off a load and a chrony does help in that department.

I am consistently getting 1 1/2 inches with this 300 and R23. It will have to do and I expect it will do just fine. That's better than many hunting rifles I have had in the past.

It is my youngest sons first hunting rifle. My first rifle was a Ruger 338 Win that I am sure I never shot under 2" with but still shot moose, Dalls sheep and deer with.

Also Reloder 23 is in stock and $23 a pound so I bought 4 cans of it and also use it in a 270. R22 is $29 a pound and rarely in stock.

Groups 2,3 and 4 all had scope adjustments between shots. The last shot was me saying to myself the upper white of the paper is a deers lungs which hit center.

I shot the first group then moved the scope 4 click up. Somehow the group barely went up but moved left as well. So I moved it 4 clicks right and got group three which I tried coming back a click or two. Group four a couple more clicks left so by this time I pretty much went right 4 and back left 6 and up a couple.

Last shot tells me to go hunting or rather have my son shoot it more to verify his POI then go hunting.
