Many here have been interested in Rel17 and to hear of its performance in various cartridges. So I just thought I'd share my results with it today in my 350WSM - even though no one else here on this board actually shoots that wildcat - that I know of anyway.

Today I used ReL17 in my 350WSM for the first time. I chronyed these loads using;

225 Partitions, WLR primers, necked up nickel plated WW 300WSM, no crimp, and a COAL of 2.850".

70/ReL 17 - 2709 (all instrumental 12' from muzzle)
72/ReL 17 - 2785
74/ReL 17 - 2845
74.5/ReL 17 - 2871
75/ReL 17 - 2892


The top load did not have any measureable case head expansion or any other indicators to suggest an overload. Pretty pleased but must test for accuracy next. That top load is 4206 ft.lbs at the muzzle and the Taylor KO is 33. With a 22" barrel I'm pretty happy about getting 2900MV.

I know of another 350WSM Basner built rifle in the states using this same 75gr load but with 225gr TBBCs. It's clocking 2950MV but with a 24" tube using Federal magnum Match primers. I've got those primers too and may give them a whirl too - might be better for accuracy - but ???.

Whelen, what was your thinking behind this build?
I also like 35's and have a small collection to hunt with but I haven't thought about the WSM cases as a parent case although it is obviously from your results a very effective otpion. Give some rifle specifics, like action, barrel,reamer specs.
Thanks

The link blargon gave above tells the story pretty much in full.

In conclusion, a very successful, practical and fairly powerful project rifle IMO. It's the best of the WSM series I think.:D Too bad Winchester went brain dead after their "315" WSM was spawned.
 
...Have you tried the Accubond? Or is the Ogive incompatable?
With ReL17 have only tried the 225Partition in my 350WSM so far.

However I have tried the 225 B-Tips (now discontinued) in the 350WSM with good range results using other powders. So the 225 accubond which is the same bullet I think with a bonded core - should be compatible. Last Christmas I acquired a box of 225 accubonds to try. Not sure when I'll get around to shooting some.
