Default 17 WSM ammo spec's

What would you do with these spec's as COMPARED to measured ammo spec's?

I don't shoot any RF except for the 22LR, (when I can get ammo),
as I perfer to use the 17 cals for the safety end/aspect etc.
So I decided to get the 17WSM rifle for some hay field ADC work.
I have been researching this case,
mainly at Rim Fire Central site and found that this case/ammo is very hit and miss for results.

This post is dealing with JUST the ammo and chamber spec's,
(as I have my own Ideas on building the rifle I want),
and what I have found in measuring almost 1300+ rds of ammo and fired case spec's.

I have posted the SAAMI spec's for this case,
and will post the results found so far from the measurements of fired cases/ammo etc.

The measured spec's are, for all brands being made,

AMMO,
The datum case lengths, SAAMI spec's = 1.010" min and 1.020" max
.236" datum hole,
1000 + rds measured,
ALL ammo would fit inside .995",
.985" = min,
.994" = max,

Ammo
For the Lead measurements, = Saami = 1.274"
I had the following,
1.214" = min,
1.226" = max,
1 rd = 1.232" (longest one ever measured)
Even the longest lead measurement would fit into the tapered throat measurement, with room to spare.
I used a 17 cal RF bbl and throated it with the 1'30" throater/reamer,
for checking of the spec's etc.

Comparing to the SAAMI spec's for the chamber and you can see what I am talking about.

The VERY liberal spec's seem to be excessive IMHO,
I know that with the RF case you can only play around with reamer/chamber spec's to get the best results.

Take a good look and the throating spec's, (as compared to the ammo measurements) and it is no wonder the poor results being reported.

What are your thoughts or Ideas?

Tia,
Don

That is why they grind custom reamers. Have a reamer ground to your minimums and then chamber a short piece of barrel and fit check the ammo before you use it in your rifle. Larry
