Been loading 7 mag with IMR 4831. Got some Reloader 22 last week and noticed it's listed in Nosler book for low grains up to 140. Skips 150 and starts again. Picked up 50 Nosler Silvertips in 150 grain. Has IMR data but no Alliant. Anyone got a load they use with this combo. I laddered up one box with IMR. Would like to do the same with the Reloader 22. Remington rifle gives me best accuracy with 61-63 grains of the IMR 4831. Federal Brass. Reminton 9.5 magnum primers or cci magnum 250 primers. Can't tell a difference. 26 inch barrel. 1-91/4 twist.
Reloader 22 and Nosler bullets
- Thread starter Wendyj
- Start date
When I have data for the one above, and the one below, I use a linear approximation method for max and min charges. This method is pretty safe as long as the bullets are of the same construction type so that barrel resistance to bullet isn't way off. Can't safely do this with a flat base on one side and a boat tail on the other.
160gr Max 63gr, 140 Max is 67.5gr. Halfway between the two is 65.25gr estimated Max for 150gr bullets.
160gr 59gr starting, 140gr 63gr starting. Halfway between the two is 61gr for a 150gr bullet starting charge.
So using a linear estimation a starting charge would be 61gr RL22 with a max of 65.2gr.
Hope this is helpful.

Jimro X2. Done it quite a few times in numerous calibers.
Not real sure you are going to get the best ballistics or accuracy from R22 and any bullet that light. It's a slow powder that MAY not burn efficiently with the lighter bullets. Post your results please. Like I said, I'm not sure and have little knowledge of the 7MM. So, I may possibly learn something. God Bless

I have used it with some Hornady 139's and 162's. It shot pretty good but I got better results with both weight bullets using RL-19.
The final load with the 162's was grouping around an inch at 300yds from my Sendero. I used them to take some nice long range hogs and one very nice 20" inside spread 8 point whitetail.

Load for the bullet weight. Who made 'em doesn't matter.
Real Winchester Silvertips had an Al cap over exposed lead. Really a capped SP. They were extremely effective bullets.
The Nosler has a polymer insert that only prevents point damage(that doesn't matter either) in the mag.

My Nosler manual calls for N160 as the most accurate powder tested with 150 Btips, Combined Technology Silver tip, and Partitions....
T. Oheir, I believe all bullets in same weight cannot be loaded the same, it can be tested, however certain shaped bullets have different powders and charges that make them shine...been there done that, what works for some bullets doesnt work for others.

Wendy, that is some fine shooting. God Bless
I have a theory about why starting loads and max/compressed loads shoot better than midrange loads.
Low density starting loads with more than 80% case fill allow the powder to "puff" around the primer flame when it goes off, allowing for a sharper initial pressure spike that ensures a good solid "ringing" of the rifle harmonics. The low fill allows very positive ignition. As case fill goes up, the amount of room for powder to move around out of the way of the primer flame goes down, making ignition more dependent on the consistency of the primer. Then you get to 100% or Compressed loads, where there is so much powder mass that the primer flame is "muffled" and the powder burns more consistently because it an only burn one way.
That's my theory on why starting charges often show good accuracy, it all seems to fall into the "primer/powder" interface.

I agree Jimro. God Bless
My #2 son took me to the range yesterday and we tested 150grn Ballistic Tips from Nosler, featuring N160. A three charge test of 5 rounds found 62 and 64 grains being good while the 63 grn performance wasnt bad, the other two were better. Rifle is Savage 111 7mm rem mag, with bushnell 3-9xr0 that came with package.
Even with max load, no signs of pressure were noticed and it shot right at moa. Now he can tweak his CBTO and closevthe group hopefully..
