Received some new special order molds from Lee yesterday!!! I have had such good performance with my TLC432-285-RF, I decided to get TLC (Tumble Lube, gas checked bullet) molds for all of my Marlin's.

The TLC359-180-RF is on the left and I designed it for my 35 Remingtons and 356 Win. It is a 180-grain bore rider design that takes the short throat and short case neck of the 35 Rem into consideration.

The TLC379-210-RF is for my Marlin chambered in 375 Win. I haven't been happy with all the bullets I've tried in this caliber. They have all been too heavy, which means too long and robs this cartridge of it's potential. I spent a lot of time in ballistics testing and it seems to me that a 205 to 215 grain bullet had the best potential.

I was going to finish my shooting with my 450 Marlin yesterday afternoon, but had to do some casting after the molds arrived! Both sets of molds cast to my dimension specs and where dropping beautiful bullets from the get go!

Ranch Dog,

Tell me more about your .35. Is it a pre-microgroove 336? What is the bore and groove diameter? I've got a 336A "H" gun that I'll probably take to the range this week for the first time. It has very wide dimensions and I suspect all SAECO 352 and RCBS 35-200FN will do is provide resistance for fire forming. SAECO 352 "mikes" about .3575" to .3585" (sans check which fits very loose on the shank) and my Marlin looks like it measures from just over .360" near the chamber to just under .360" at the muzzle. I've been meaning to call SAECO about their undersized mould. I'm using BHN 16 metal and the bullets are dropping from 352's cavities at just over 240 grains.

Anyway, I like the looks of your mould and am anxious to find out how it shoots... it looks heavier than 180 though.

MC...

I've got 336SC "K" and the 336D. The "SC" slugs out at .3583 and the "D" .3585". The problem I've had with cast bullets is that with WFN bullets they engage the rifling at a cartridge OAL of about 2.18". Both rifles are the same. Here is a drawing of the bullet.

Cast with 1/10, tin/lead, the bullet hits the scales at 181-grains with the gas check. The Speer 180-grain FP shoots so well out of both my rifles, I thought I would give a lead bullet in this weight a try.

Ranch Dog,

Good luck at the range. Wow, what a difference a couple years can make in terms of internal dimensions. I wish my "H" gun was as tight. I'll probably end up having Mountain Molds cut an oversize mould for said .35 which looks to be approaching the bore size of those 9.3mm Mauser rounds; i.e., a .363" as-cast bullet probably won't be too fat!
