Why Not:

What powder are you using to get 2200 fps from a 220 grain bullet?

My maximum velocity with the 200's was 2250fps.

I have chatted with Ted about this and I believe he was pushing them with BL-C2, but I think you can also get that velocity by using LVR as well.

Yes, and Accurate 2520 will get you there easily, too. This from Quickload.

Green highlighting is mine.

The thing we need to remember is that the factory 35 Rem loads are purposely kept low. Just checked, and SAAMI published maximum is 33,500 psi. This is, of course, for use in the older Remington 14 series pump and series 8 semi-auto rifles which are weaker actions.

If the Marlin 336 is capable of handling the 30-30, which is a tad over 42,000 psi in the factory load, then it can certainly handle the same pressure in a 35 Rem.

Thankyou dave!
I have lots of the h4895. Thats what I use for my 200's. I will have to find some 220's to give it a try!

I cannot see getting 2200 from a 220'grain bullet in this cartridge. Not enough case capacity.

Does anyone have load data to this effect?

Thanks guys! I will be doing some load development as soon as I can locate some 220's!

This would definitely change the overall level of performance of this cartridge!

You are welcome.

Especially when you consider the velocities are out of a 20" barrel, it really is a fine performer.

Don't forget to check back in with your results.

Best,
Ted
 
I had a Guide Gun and the XLR (both in .45-70). The XLR, due to the longer barrel is a much better handling gun. Far nicer recoil characteristic.

I'd never consider bobbing the barrel on an XLR, in fact I sold the Guide Gun, and kept the XLR.

To each his own, I guess...
