I am curious if anyone has tried this powder wit the 230gr bergers in 300rum? Alsi wondering how it compares to the RL-33. I can't seem to find any RL33 but I found a small stash of the norma powder. thanks

Here's my experience with Norma 217 albeit w/30-378 Wtby.

[FONT="]You can reduce powder not more than 3 grain, but how long is free bore with bullet? You need at least 3mm or more. How strong is bullet sitting in.[/FONT]
[FONT="]Is barrel clean? How is velocity. Check this thing. [/FONT]

[FONT="]I shot 180gr Nosler Partition with 110gr Norma 217, in Weatherby cases and Fed 215. I encountered sticky bolt lift with extractor cut mark on case head. Bolt lift and extraction normal after bolt lift cleared extractor cut -- maybe 1/32".
Same thing with 113.5gr Norma 217 and 168gr Barnes TTSX.
This does not happen with 168gr barnes TTSX and Hodgdon 50BMG (119.0gr) at 3,427 fps.
Can I reduce powder charge with Norma 217 -- if so, how much?
Thanks,
Paul

[FONT="]Hi Paul[/FONT]
[FONT="]Yes we have same loads. if we go down on powder what is normal, barrel time be longer and pressure went up.[/FONT]
[FONT="]So it is for safety. Don't load different than manual is saying. [/FONT]
Kenneth,
Update and Recap on .30-378 Weatherby Maygnum
Weatherby specs list freebore is .361" for the .30-378 Wtby Mag. Best I can tell freebore on the rifle I have is at least .361 and maybe a bit more.
Rifle is clean.
Fired cases allow bullet to slide in and out freely (necks not too thick).
Barrel Length: 26"
Action: Dakota 97
Loaded with Norma 217 (Lot Number 0603 135067)
1x factory fired Weatherby cases
Federal 215 magnum primers
168gr Barnes Tipped TSX
Seated at 3.645" OAL
Chronograh set 20' (about 6 meters) from muzzle.
Per your instructions, I started with one round at 113.5gr as listed in manual for 165gr oryx – sticky bolt uplift (for about the width of the extractor cut), extractor cut mark on case head, extraction normal and velocity didn't register on chronograph. Temp – 65-70 Deg F
After your email (saying drop charge no more than 3 grains) I tried 111.5gr – velocity average 3,609 fps at 70 Deg F. Bolt lift not completely normal with resistance on initial uplift and some resistance midway thru bolt uplift (each case was a bit different) – extractor cut marks on several case heads, and extraction was normal.
Dropped charge to 110.5gr – velocity 3,567 fps. Bolt lift and case head marks less noticeable than 111.5gr but still evident to some degree. Temp 65 Deg F
Dropped charge to 109.5gr – velocity 3,520 fps. Bolt lift normal, case head normal. Temp 60 Deg F.
It looks like I should stop at 109.5gr – does this sound reasonable and 3,520 fps.
..

Paul
