There is a lot of mis-information at that site. Anytime you want to use loading data remember to check the loads against a manual or two. There are more overloads there than any other site I have ever visited. |
I used to think that Steve had some overloads as well. That is until I did a lot of double checking in many manuals.
For example, Hodgdon lists 54gr of H4895 as max in 300WSM 165gr. Steve lists 57.8gr as max for 165gr bullet. That would seem to indicate that he has listed an overload. Until you dig deeper and find that Sierra #5 lists 57.8gr of H4895 as max for 165gr bullet. Every max load that I have found on Steve's site can be found published in a reloading manual

Although I agree with you to some degree, steve4102. I have to admit that some of his (stevespages) load data is somewhat hard to find in other manuals. I do keep his site on my favorite list and use his site as a reference for some load data, I am hard pressed to use his higher loads as I find that 36.5 grains of W-748 to be a bit steep for a .30 WCF (.30-30 Win) using a 170 grain bullet. The highest that I have used is 33.0 grains and that exceeded factory by about 100 fps. I can just amagin what 36.5 grains would do. I would MORE THEN CAUTION anyone planning to use his higher charge levels.

Be aware that around 2000/2001 Hodgdon reduced their loads dramatically in their manuals. I have manuals before that time that are all consistant with their 7STW data but then suddenly all loads got reduced by around 7-10%. Some people felt it was due to them wanting a tad more breathing room for legal reasons. I emailed and asked them and they only said "we retested the data and the current data is what we found"

Powder changes from lot to lot and I suppose it could change a lot from year to year. I try to keep current data all the time but those manuals are expensive and I own a bunch - I could no more replace them all each time a new one came out - Thats why I keep the manufacturer's websites and phone numbers close by. I have been calling Sierra so much I know who to ask for and he recognizes me. I figure if a powder company is reducing its loads because it migh be high enough to be considered marginal in a gun manufactured for it then I will use the lower charge. A few extra fps has never been worth much to me without accuracy. Most of my loads are well below maximum - they are where it gives me the best and most consistant accuracy.

Yup, we have to be careful with his and all load data. Same old, same old, Starting low and working up is the only safe way to do it.
BTW, I did find Hornady data that lists 36.5gr of W-748 as max for the .30 WCF with 170gr bullet. It has it listed at 2100fps out of a 20in M94.

I'm getting 2100fps using 33.0 grains of W-748 and a 170 grain Speer FN now from a Mod 94 20" barrel...

Some of my Hornady data lists 36.5 gr as Max with a velocity of 2200 fps using a 170 gr bullet and 20" bbl and another Hornady manual lists 35.2 gr as Max with 2100 fps velocity. As always work up slowly and watch for high pressure signs.

Hi Sniper
Yes I got it right now I think I did use the Lee crimper too.
The test report is here
www.huntingnut.com/ind...amp;t=2323
Apparently, I got two fold problem. First of all, I got a very tight chamber. And second, I have different BRAND of cases.
The ones that works are PMC cases and the ones that don't are Norinco cases. The norinco are a tad thicker on the wall. This made the neck much thicker than the chamber could handle.
I will trim the neck wall later
Anyhow, htanks for your help.
Gelan
PS. Can't look at the keyboard? is it the gut? too much cookie over Christmas?
