If I seat 300 grain Nosler Partitiions so the crimp lands at least halfway in the bullet's crimp groove, the overall length of the cartridge is 2.520". I'm using new Starline brass trimmed to 2.095" and a Lee Factory Crimp die.

I seated some rounds at 2.550". The end of the case just reached into the crimping groove. After crimping the lengths varied from 2.550" to 2.530". Some of the rounds were quite hard to crimp, others were easier. This ammo averaged 2151 fps. SD=17.32.

The ammo loaded to 2.520" averaged 2190 fps. SD=18.86.

When loading once fired Remington brass trimmed to 2.095" the length after crimping remains 2.550". These loads averaged 2088 fps with an SD of 31.52.

Oddly enough all of these combinations group 5 rounds at 1.75". I tried new Starline brass in hopes of improving accuracy; no such luck.

All of the above loads used 55 grains of H4198. The barrel is 16" long. I'm wondering what kind of accuracy others are getting and what your thoughts are on the safety of this load with the new brass.

I could also use some tips on benchresting a light rifle that exhibits a fair amount of muzzle rise. I have considered that the loads may be more accurate and my shooting stinks. I'm also wondering how to time shots over a chronograph for consistent results. It seems that a cold bore shoots slower. How long do you wait between shots?

Thanks for any input.

The barrel is 16" long. benchresting a 16 inch barreled Ok fair enough if its been scoped then try
25 lb's sacks of shot over the top of the barrel to hold it down.. could i ask a dumb question Why is the barrel so short you cant hunt with it legally
at least not in Oregon must be atleast an 18 incher.
Just wanted to know .. anyway back to the question
Man i think porting its going to be the answer .
or your going to be stuck shooting low to mild rounds through it FOREVER :(
just my thoughts on it

Mr. Potts,

I'll give the shot bags a try, thanks.

The barrel is actually 16-3/8" in length; its what you get when you cut a Guide Gun right behind the ports. I thought the ports pushed around a little too much debris. I hunt mostly in close cover so I decided to cut the barrel. Georgia imposes no restriction on barrel length. Can you hunt with handguns in Oregon?

The loads meet my hunting requirements so I probably won't change the rifle. The gun is quite manageable offhand or from field positions. I guess I'm looking for more accuracy just for the fun of it. One of the places that I hunt requires a 200 yard shot or a 150 yard crawl. After the crawl I decided to try higher velocity ammo.

Ok i see
It's a shame you cut the barrel off :(
As far as hand gun hunting the answer is yes theres a season for it and theres been one since 1974 in Oregon
For Deer and Elk then thay added prong horn
and goat and bear. I tryed it the first year with
my old 357 Ruger i d a r n ner got run over by the Elk whole herd came down the high running i had to hide behind a snag i hit a forked horned bull right in the ...................
Ya thats right you know were sec shot went wild
number 3 went ? god knows more then likly some poor guys cow fell over dead in the next field.
Forth round hit right in the back of the head and it hit the ground it was about 75 yards away and
running at a good clip when i hit it..

direwolf would you mind sending me a PM
i would like to talk to you about somthing off the form.
Thanks
Pottsy

direwolf, I've been told that Starline brass needs to be fired once, and then it will start to shine for accuracy.....
