1940 Model 70 30/06 with 20 inch barrel. 1935 winchester model 61 22LR first year made. 1947 model 94 32 Special, and a 1939 I think High Standard Model D target from New York City. All great shooters.
Yesterday I shot some ladder tests using Superformance with 140gr NoslerBt 215M primer and Win case OAL was 2.760 stepps were 2844 FPS,
2875 FPS, 2871 FPS, 2918 FPS, 2940 FPS, 2988 FPS with no sticky boly. I,m going to load more at the 2918 FPS and 2940 FPS. Also loaded 3 loads using PP4000mr...
Shot some 160gr Nosler Partitions today, I got 2770FPS SD 9.4. Also shot some PP4000mr using 145gr Speer BT bullets. First load was 2900 FPS and .5 gr more was 2917 FPS
I was using 215M primers and Starline cases. PP2000Mr with TTSX 120gr did 3145 FPS With WLRM primers Win cases.2.740 OAL...
First if I was going to shoot 160gr Accubonds I would use RL17, PP4000mr or RL26. Personnely I only shoot 160gr Nosler Partitions in my 7mm-08.
Because they are shorter and take up less space in the case. I only use Winchester cases, they hold more powder. I use Federal 215M or Win WLRM...
RL23, RL22, MRP and RL26 All worked good in my 257 Roberts with 115gr Nosler Partitions. MRP and RL23 were most accurate. RL26 gave highest velocity, but slightly less accurate. I got over 3100 FPS with all of them except RL26 It gave close to 3200FPS.
In my 270 win if I,m using RL23 I get 3087 FPS with 140gr bullets. With 150gr Nosler Partitions and MRP I get 3084 FPS. Mostly I use the RL23 because it is temperature stable, MRP not so much, but very accurate. I have killed Elk with both.
I do not have a 280 anything but I do have other rifles and I have tryed RL23 in most of them. Heaviest bullet I shoot in my 270 Win is 150gr, But I only use MRP for that. It was fast and very accurate. With 140gr Bullets 58.5gr. was as hot as I could go with the RL23 I got 3094 FPS in my new...
I have both MRP and RL22. I have shot the same loads on the same day. If loads are equal RL22 will get you a littlemore speed. the MRP will also drive a heavier bullet faster.
But if you start increasing the loads the RL22 will get to high a pressure. The MRP will take about 1 to 1.5 more...
The RL26 loads are compressed, but seem to work. Like I said I only use flat based bullets. Actually I have had loads even more compressed, like MRP with 160gr bullets. I tryed RL23 but you are right about that one it needs a bigger case. I got 2868 FPS using RL26 with 150gr Speer BT S.D. was...
My brother had a model 70 in 7/57 he only shot 139 gr hornady bullets in it because we were only hunting deer. I loaded the
Handloads for him, I used IMR 4320 for the loads. He thought he was getting 2900 FPS. Not sure if that was right. I,m going to get some 154gr Hornady SST flat based. I...
H4831 is great if you already have it but the three I mentioned all have there advantages. I,m using the RL23
with 140gr Trophy Bonded Tipped or Accubonds for deer. For Elk sometimes I use MRP as it is extremely accurate and
very fast. Also it is able to be used in many other calibers. Like...
Shot off a few rounds yesterday, from my Tikka Superlite with 22.4" barrel. RL26 using 160gr Nosler partitions 215M primers
and Win cases 2.760 OAL gave 2760FPS. For some reason accuracy was not to good. I,ll add another .5gr and see what happens.
I loaded Superformance with 140gr Ballistic...
