Recent reloading findings and data

I've been concentrating as of late on my new 30-06, my 7mm Mag, and most recently my 243. Just having fan really and looking to find combos for the first two for possibly big game and or coyotes and specifically with the 243 for coyotes. Some of you might remember from my post on my 30-06 it is a Rem 700 ADL which was wearing a Nichols 3x9 scope and had about a six pound trigger pull. Even with that horrid trigger I was getting tight groups with Federal power shok ammo. Well, I recently took it in to my gunsmith who gave it a nice trigger job (just under three pounds which I like for hunting) and he also lapped and trued up the scope mounts and boresighted a Luepold Riflemen 3x9 power for me on it. Took it to the range and found with that trigger I was constantly hitting 1 to 1/2 inch three shot groups with that Federal 150 gr power shok ammo at a 100. Next it was time to try some reloads. I'll spare you the data on the recipe that didn't impress me (2 to 3 inch groups at a 100) and give you the data on the one that shined.

The bullet was a 165 gr Nosler Ballistic Tip using Win virgin necksized brass. This was being pushed by H 4350 and CCI BR2 bench rest primers. My Max COL was the standard 3.34 for the -06. As I didn't have a Nosler manual I followed the data from a Hornady book for their 165 gr bullets and went from the lowest to their max load and looking for signs of high pressures as I shot each load up to max. The hornady book used a Model 70 with 23 inch barrel for their testing so my 22 inch barrel should be close to it's listed velocities but as I don't have a chronograph so don't know exactly.

The loads were as follows:
1st 52.3 grs listed as 2500 fps
2nd 54.5 grs listed as 2600 fps
3rd 56.7 grs listed as 2800 fps
4th 58.9 grs listed as 2900 fps

Re: Recent reloading findings and data

I made five rounds for each loading and used the first one to shoot the gun without aiming or having my face down near the action as a test load. This is too ensure pressures for whatever reason aren't high and avoid blowing my face up. Each round extracted out of the chamber easily and the primers showed no signs of undo pressure until the hottest load which did show slight flattening (slight) of the primer, but still extracted easily. Each loading gave anywhere from one inch to 3/4 inch four shot groups at 100 yards. This made me very happy and I would feel very confident using the Nosler Ballistic Tip on Antelope and possibly Mule deer (would like to hear comments on what others think of this bullet for Mulies).

This pic is from the 56.7 load (not the five taped shots above but rather the four shots touching)

Re: Recent reloading findings and data

The next rifle up is my 243 which I'm very happy to say I've found my coyote killing recipe for. Up until recently I was very mistaken in thinking that 1 in 10 barrel twist rate was not good for stabilizing lighter bullets in the 243. Partly because in my own experience with my rifle, which is a Winchester Model 70 Classic Featherweight, it shot most 100 gr factory ammo very well from 1 1/2 inch to one inch groups. But, when I tried lighter factory ammo 85 and 80 grain bullets the groups opened up wide to two inches which I don't like at all and won't hunt with. I attributed this to the twist rate and I think I also read that somewhere on the Internets and took it as gospel. Well, luckily I ran into a couple of of people who corrected this erroneous thinking on my part and assured me a 1 in 10 twist will stabilize the lighter bullets and I just needed to find the right recipe to likely get good accuracy with them.

I purchased two boxes of Nosler Ballistic Tips one in 70 gr and one in 55 gr. With the 70 grainer I candle smoked the bullet to see the lans mark and ran it just off the lans at a Max COL of 2.75. My recipe for both the 55 and 70 gr used Win fireformed neck sized brass with CCI Large rifle primers and Varget powder. I used the Nosler data which for the 70 grainer was 38, then 40, and finally 42 grains.

The lowest load, 38 grains, gave me the best accuracy with consistent 3/4 to 1/2 inch groups at one hundred yards. Their data was derived from a 24 inch barrel listing the velocity at 3,338 fps. I reckon my gun with it's 22 inch barrel should be around 3,100 to 3,200 fps which I can live with. The highest load, 42 grains listed a velocity of 3,616, which is cooking, but I think 3200 is still smoking enough and won't be as hard on the barrel. Heck that's 223 velocities with a heavier 70 gr bullet.

Here's one of the best groups with that load.

Re: Recent reloading findings and data

I also had cooked up some 120 Nosler Ballistic Tips for the 7mm Mag as a possible flat shooting long range coyote smacker and maybe even for antelope. I used Federal Premium neck sized brass, CCI Large Rifle primers, and IMR 4831, using the Nosler loads and each one consistently gave me 1 and 1/2 inch accuracy. I'd use that accuracy for antelope on up but not for coyotes. The gun is a Howa which I had a Boyds thumbhole stock put on it and glass bedded and free floated with Luepold MKII 3X9 on it.

Re: Recent reloading findings and data

And finally the coyote killing shotgun, my Mossberg 500 sporting a 20 inch barrel and a Carlsons Dead Coyote choke. I used Federal 3 inch lead BB loads and Remington #4 3 inch buckshot with 41 pellets. I found that how I aim using the bead my shot goes high. In order to compensate I have to aim anywhere from six to ten inches low from where I want to hit (on the targets the orange dot). I figure when aiming at a dog to hold on his feet and the pattern should catch him pretty good.
